Answer:

2.5 miles west and 1 mile north

Step-by-step explanation:

Step-by-step explanation:

For first triangle,

sin 45 = 3 / d

1 / root 2 = 3 / d

d = 3 root 2

For second triangle,

tan 60 = 7 / a

root 3 = 7 / a

a = 7 / root 3

Answer:

log(144) or 2.158

Step-by-step explanation:

Answer:

log(144)

Step-by-step explanation:

When you evaluate and multiply it out, this is what it turns out to be. Hope this helps!!!:)

Answer:

One reason, is because it clearer and easier to read.

Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.

3 is the number being multiplied, and 5 tells you how many times.

Janice is currently 4.

In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.

I hope this helps!

Answer:

4v

Step-by-step explanation:

The value of x is already known (x=4v) so if it is a trick question then just know its already there. If it was 4=xv then x would be 4/v but obviously it's not asking that... If you were looking for the value of v it would be x/4...

Answer:

1 1/6

Step-by-step explanation:

You can convert 7/6 into a mixed number by subtracting 1 from the improper fraction, because 1= 6/6

7/6 -6/6= 1 1/6

Answer:

7/6 would be 1 1/6

Step-by-step explanation:

To make it a number in general turn into a decimal.

Answer:

A=4

Step-by-step explanation:

you use the Pythagorean Theorem,

 a triangle having a Leg b length of 3 and a Hypotenuse c length of 5 would have a Leg a length of 4.

Here is how I solved for Leg a using the Pythagorean Theorem.

Leg a = sqrt[ (Hypotenuse c)2 - (Leg b)2 ]

Leg a = sqrt[ (5)2 - (3)2 ]

Leg a = sqrt[ 25 - 9 ]

Leg a = sqrt[ 16 ]

Leg a = 4

Answer:

7/8 + 4/8 = 1 3/8.

Step-by-step explanation:

In words the answer is 1 and 3/8.

Answer:

x = 2

Step-by-step explanation:

Distribute

3 (−4) = 2 (−2+1)

3 − 12 = 2 (-2x +1)

Distrubute again

3x - 12 = -4x + 2

Add twelve to both sides of the equation

Simpfly

3x = -4x + 14

Add 4x to both sides of the equation

simpfly

7x = 14

Divide both sides of the equation by the same term

Simpfly

x = 2

Answer:

  obtuse

Step-by-step explanation:

You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.

The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.

The triangle is obtuse.

__

Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).

In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:

  hypotenuse = √(6² +8²) = √100 = 10

Your long side is longer, so your largest angle is larger than 90°.

Law of Cosines:

  angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°

Answer:

[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]

Step-by-step explanation:

To convert from vertex form to standard form, we can simply expand.

So, we have:

[tex]\displaystyle f(x)=\frac{1}{2}(x-2)^2-4[/tex]

Expand the square:

[tex]\displaystyle f(x)=\frac{1}{2}(x^2-4x+4)-4[/tex]

Distribute:

[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x+2-4[/tex]

Simplify:

[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]

Answer:

-38

Step-by-step explanation:

Let's say that x= 1st number and y=2nd number.

In order to find the first number,  you have to find out the 2nd number which it says, "5 less than a second number", it would be y-5. then it says the "5 times the first is 8 more than 6 times the second". then there should be an equal sign because there is the word "is". The expression would be: 5(y-5)=6y+8. then solve the y. which is -33, then plug in the y to the y-5 and there you go!

Answer:

its 34

Step-by-step explanation: i

Answer:

In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.

then if we have the points (a, b) and (c, d)

The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.

Then the vertical change between the points (2.5 , 1) and (5, 2) is:

2 - 1 = 1 unit.

The horizontal change between the points (2.5, 1) and (5, 2) is:

5 - 2.5 = 2.5 units.
