Answer: m<1 refers to the measure of an angle in a plane. The symbol < indicates that it is a smaller angle than a right angle which has a measure of 90 degrees. The value of m<1 is the measure of that angle in degrees.

36°, 70 degree and 1 degree are all measures of angles, but they are not necessarily the measure of m<1. Without any further context or information, it is not possible to say what m<1 is equal to.

The range of scores that Steve needs to get an average of 70 to 79 is 66 to 87 Points.

To find the range of scores that Steve needs to have to stay in the 70 to 79 range we first need to define the variables that we need to find.

Let x = Score that Steve needs

Since the exam is worth 3 exams, we will then use 3x to denote the weight of the final exam.

Now we need to add all the other exams and divide it by the number of exams.

[tex]\frac{3x + 70+77+71+71}{7} = 70[/tex]

3x + 292 = 7 *70

3x = 490 -292

3x = 198

[tex]\frac{3x}{3} =\frac{198}{3}[/tex]

x = 66

Now let's look for the score that Steve needs to get to a 79 average.

[tex]\frac{3x + 70+77+71+71}{7} = 79[/tex]

3x + 292 = 7 * 79

3x + 292 = 553

3x = 553 - 292

3x = 261

x = 87

So the range of scores is 66 to 87 Points.

The probability of rolling a one on the first die and a four on the second die is 1/36.

This is because there are six possible outcomes for each die (1, 2, 3, 4, 5, and 6) and the probability of rolling a specific number on one die is 1/6. To find the probability of rolling a specific number on two dice, you would multiply the individual probabilities of each die (1/6 x 1/6 = 1/36). Since there is only one combination of rolling a one on the first die and a four on the second die, the probability is 1/36.

Note that the rule that describes the transformation shown is: (x,y) → (x+7,-y)(Number 2)

A transformation is a broad phrase covering four distinct methods of changing the shape and/or location of a point, line, or geometric figure. The Pre-Image is the original shape of the item, and the Image is the final shape and location of the object after the transformation.

Thus, with regard to the transformation above,

At Point A: The original coordinate of point A was (-6,-6).

The coordinate after the transformation is A'(1,6), which eliminates option 3.

At Point B:

The original coordinate of point B was (-2,4).

After the transformation, we have B'(5,-4), which eliminates option 1 and option 4. It is therefore right to state that (x,y) → (x+7,-y) is the correct representation of the transformation.

The formula for the cost, C, of hiring a DJ for n hours is C = hn + e

a. The formula for the cost, C, of hiring a DJ for n hours is C = hn + e, where h is the hourly fee and e is the equipment setup fee.

b. To find the inverse of the formula, we can solve for n in terms of C and h:

n = (C - e) / h

The new formula represents the number of hours the DJ was hired for given the cost, C, and the hourly fee, h.

c. If the DJ charged $550, we can use the inverse formula to find the number of hours she was hired for.

n = (550 - e) / h

where e is equipment setup fee.

Since we are not given the equipment setup fee, we can't calculate the number of hours she was hired for.

The mass of the wine can be found by multiplying the density of the wine (0.8 kg/litre) by the volume of the wine (20 litres). The mass of the wine is 16 kg.

Its density is how much "stuff" can fit into a certain quantity of space. For instance, a block of the more resilient, lighter element gold (Au) will have a higher density than a block of the more substantial element lead (Pb) (Au). Styrofoam blocks are not as dense as bricks. Mass per unit volume serves as its definition.

We use the word "density" to indicate how much space (or "volume") an object or substance occupies in relation to the amount of matter contained therein (its mass). Density can also be defined as the quantity of mass per unit of volume.

mass = density x volume

mass = 0.8 kg/litre x 20 litres

mass = 16 kg

The solution of the trigonometric function in the interval is x = 0

A trigonometric function is an equation that contains the trigonometric ratios.

Given the trigonometric function secx + tanx = 1, we proceed to solve it as  follows.

secx + tanx = 1

Using the trigonometric identity tan²x + 1 = sec²x

⇒ secx = √(1 + tan²x)

So, substituting this into the equation, we have that

secx + tanx = 1

√(1 + tan²x) + tanx = 1

√(1 + tan²x) = 1 - tanx

Squaring both sides of the equation, we have that

√(1 + tan²x) = 1 - tanx

√(1 + tan²x)² = (1 - tanx)²

1 + tan²x = 1 - 2tanx + tan²x

Substracting 1 from both sides, we have that

1 - 1 + tan²x = 1 - 1 - 2tanx + tan²x

0 + tan²x = 0 - 2tanx + tan²x

tan²x = - 2tanx + tan²x

Substracting tan²x from both sides, we have that

tan²x - tan²x= - 2tanx + tan²x - tan²x

0 = -2tanx + 0

0 = -2tanx

tanx = 0/-2

tanx = 0

taking inverse tan, we have that

x = tan⁻¹0

x = 0

So, the solution is x = 0

The factored form of 26x^5 - 13x is 13x(2x^4 - 1).

What is the greatest common factor?

The greatest common factor (GCF), also known as the greatest common divisor (GCD) or highest common factor (HCF), is a concept in mathematics that refers to the largest positive integer that divides two or more integers without a remainder.

To factor 26x^5 - 13x using the greatest common factor, we need to find the greatest common factor of the two terms.

26x^5 = 213x^5

13x = 13*x

The greatest common factor of the two terms is 13x.

So we can factor it out:

26x^5 - 13x = (13x) (2x^4 - 1)

Hence, the factored form of 26x^5 - 13x is 13x(2x^4 - 1).

A) x²  - 2x - 13 in the form of (x + c)²  + d is (x - 1)²  - 15, and the value of

c = -1, d = -15

B) The solutions of the equation are 1+ √15 and 1- √15.

A quadratic equation is a type of polynomial equation that has the general form of ax² + bx + c = 0, where x is the variable, a, b, and c are constants, and a is not equal to zero.

a) To write x²  - 2x - 13 in the form (x + c)²  + d, we can complete the square.

First, we add and subtract (2/2)²  = 1 to get:

x²  - 2x - 13 = x²  - 2x - 13 + 1 - 1

Next, we group the terms:

(x²  - 2x) - 14 = (x²  - 2x + 1) - 15

Now, we can see that the left side of the equation is a perfect square trinomial. To complete the square, we add the square of half of the coefficient of the x term, which is (1)² = 1 to both sides:

(x - 1)²  - 15 = 0

So, x² - 2x - 13 = (x - 1)²  - 15

c = -1, d = -15

b) Using the answer from part a, we know that x² - 2x - 13 = (x - 1)² - 15

=0

so (x-1)² = 15

x-1 = ± √15

x = 1 ± √15

The speed travelled by mars in miles per minutes is 900. As Given that the mars revolves around the sun at a rate of approximately 15 miles per second.

We know that , Speed = distance / time

Hence we have speed of the mars as  15 miles/sec.

To convert the rate from miles/sec to miles/ minute we have to multiply the given with minute i.e 60 sec.

                    miles x min    =   miles x 60 sec          

                     sec x min              sec x min

           since , 1 minute = 60 sec

 hence, new speed = 15 x 60 miles/ minute.

Therefore , the speed travelled by mars in miles per minutes is 900.

Answer:

$20239.6

Step-by-step explanation:

The amount financed for the car is $25,800 - $8,000 = $17,800.

To find the monthly payment, you can use the formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

where M is the monthly payment, P is the amount financed, i is the monthly interest rate (3.99%/12), and n is the number of payments (60 months).

So,

i = 3.99%/12 = 0.00399

n = 60

M = $17,800 [ 0.00399(1 + 0.00399)^60 ] / [ (1 + 0.00399)^60 – 1]

M ≈ $337.31

So, Michelle will make monthly payments of $337.31 for 60 months.

To find the total amount that Michelle will pay for the car, you can multiply the monthly payment by the number of payments:

$337.31 x 60 = $20239.6

So, the total amount that Michelle will pay for the car is $20239.6

Answer:

Target (option b/second option)

Step-by-step explanation:

We have to first convert the fraction rates into percentage rates. To change a fraction to a percentage, you can divide the numerator by the denominator then multiply the result by 100. Alternatively, you can multiply the numerator by 100 first then divide the result by the denominator of the fraction.

1/2 = 50%

1/3 = 33.33%

Now reviewing this data, we see that a 50% decrease of a price is more than a 33.33% decrease.

Explanation:

We'll use the pythagorean theorem converse.

Consider a triangle with sides a,b,c where c is the longest side.

There are 3 scenarios possible:

The middle or second scenario is probably what you're most familiar with. That's the famous pythagorean theorem without the term "converse" attached to it.

--------------

The two given sides are 8 inches and 10 inches.

Let's say the third side was 5 inches (choice F)

This means we have a triangle with sides a = 5, b = 8, c = 10

Then compute the following:

Since 89 < 100, we see that a^2+b^2 < c^2 is the case. Therefore the triangle with sides 5,8,10 is obtuse.

This will allow us to rule out choice F since we're looking for an acute triangle.

--------------

Now onto choice G.

This time the sides are: a = 6, b = 8, c = 10

Both results (a^2+b^2 and c^2) are the same at 100; so we see that a^2+b^2 = c^2.

Therefore we have a right triangle. We can rule out choice G.

--------------

Now onto choice H.

The triangle now has sides: a = 8, b = 10, c = 12

Since 164 > 144, we see that a^2+b^2 > c^2 is the case. Therefore the triangle with side lengths 8,10,12 is acute.

--------------

For the sake of completeness, let's go over choice J.

We find 164 < 169 which leads to the scenario a^2+b^2 < c^2. The triangle for choice J is obtuse. We can rule out choice J.

You can use something like GeoGebra to help visually verify these results.
