Answer:

  False

Step-by-step explanation:

The terms of a geometric series would have a common ratio. The terms of this series do not. (The differences increase by 1 each time, so it is a quadratic series.)

False, the series is not geometric.

Answer:

Solution :-

We are given with the series

6 + 8 + 11 + 15 + 20 + 26

Since

the series is increasing by +1. So, it will be not a geometric series

14. What is the length of a diagonal of rectangle EFGH? Show your work

Answers

Answer:

The length of the diagonal of the rectangle is of [tex]\sqrt{58}[/tex] units.

Step-by-step explanation:

Pythagorean theorem:

The square of the hypothenuse h is equal to the sum of the squares of sides a and b, that is:

[tex]h^2 = a^2 + b^2[/tex]

Diagonal of a rectangle:

The diagonal is the hypothenuse, while the sides are a and b.

In this question:

The height has coordinates are y = 9 and y = 12, so the height is [tex]a = 12 - 9 = 3[/tex]

The length has coordinates at [tex]x = -6, x = -13[/tex], so the length is [tex]b = -6 - (-13) = 7[/tex]

Diagonal:

[tex]d^2 = a^2 + b^2[/tex]

[tex]d^2 = 3^2 + 7^2[/tex]

[tex]d^2 = 9 + 49[/tex]

[tex]d^2 = 58[/tex]

[tex]d = \sqrt{58}[/tex]

The length of the diagonal of the rectangle is of [tex]\sqrt{58}[/tex] units.

Which is the best approximation to a solution of the equation ln x = x - 2

- 2
1
2
3

Answers

Answer:

Here we can not see the graph, so I will upload a new graph for this case.

To solve the equation:

Ln(x) = x - 2

We can first graph the equations:

y = Ln(x)

y = x - 2

And find the point where these graphs intersect.

In the graph we can see two intersects.

One (the first one) is near the point ( 0.15, -1.85)

And the other intersection is near the point (3.14, 1.14)

Then two possible values of x that are solutions of:

ln(x) = x - 2

are:

x = 0.15

x = 3.14

In ΔPQR, the measure of ∠R=90°, QP = 85, RQ = 13, and PR = 84. What ratio represents the cosecant of ∠P?

Answers

Given:

In ΔPQR, the measure of ∠R=90°, QP = 85, RQ = 13, and PR = 84.

To find:

The cosecant of ∠P.

Solution:

In a right angle triangle,

[tex]\text{cosec}\theta =\dfrac{Hypotenuse}{Perpendicular}[/tex]

It is also written as:

[tex]\text{cosec}\theta =\dfrac{Hypotenuse}{Opposite}[/tex]

In triangle PQR, QP is the hypotenuse because ∠R=90°.

[tex]\text{cosec}P =\dfrac{QP}{RQ}[/tex]

[tex]\text{cosec}P =\dfrac{85}{13}[/tex]

Therefore, the required trigonometric ratio is [tex]\text{cosec}P =\dfrac{85}{13}[/tex].

Kyle is buying a $220 bicycle if the bicycle is on sale for 35% off how much will he save

Answers

Answer:

$77

Step-by-step explanation:

Okay so first, we know that the bicycle is 220 dollars. So we got to  multiply that to the percent. We can't muiltiply it into the percent yet so we turn that percent into 0.35

220 * 0.35

This equals to 77. That's the answer but it's not that simple, cause we aren't finished!

So we know that 35 percent of 220 is 77 dollars. So subtract that to 220!

220 - 77

This is equal to 143. Now how much will he save? He will save 220 - 143, which is 77! That's how we know the answer! I'm sure this is correct, if itsn't please comment! Have a great day!

Answer:

$143

Step-by-step explanation you wanna see how much 35% is out of 220

35% = 0.35

220 * 0.35 = 77 = discount

Now you want to see how much it will be when the discount is applied

220-77 = 143

The bicycle is $143 when discount is applied, you save $77

If event A is certain to occur, what is P(A)?

Answers

Answer:

Unless I'm misunderstanding it should be 100% or 1/1  because something that is 100% likely to happen will always happen.

Step-by-step explanation:

If there is anything else that may change my understanding of this please send it otherwise I hope this helps.

The value of P(A) is 1 where A is the event that is certain to occur because the probability of any event is 1 which means that event is certain to occur.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that:

If event A is certain to occur.

As we know,

From the definition of probability, the ratio of the number of favorable outcomes to the total number of outcomes

The value of the probability lies between 0 to 1 or [0, 1]

If the probability of any event is 0 that means that event cannot happen.

If the probability of any event is 1 that means that event is certain to occur.

Event A is certain to occure.

P(A) = 1

Thus, the value of P(A) is 1 where A is the event that is certain to occur because the probability of any event is 1 which means that event is certain to occur.

What is the value of x in the equation −x = 3 − 4x + 6?

−9
−3

Answers

Answer:

The answer is 3

Answer:

x = 3

Step-by-step explanation:

-x = 3 - 4x +6

make the -4x positive and then add it to the -x

-x = 3 +6

+4x

3x = 3 +6

then add the 3 +6 together

3x = 3 + 6

         9

3x = 9

we want to get X alone so we are going to divide 3 by both sides

3x/3 = 9/3

1x = 3

and if you did not know we usually don't show the "1" if it is in front of a exponent (you just have to remember that there is a one there)

the sum of the interior angles of a triangle is 180°

Thus our equation is

simplify addition:

[tex] \displaystyle \angle1 + {107}^{ \circ} = {180}^{ \circ} [/tex]

cancel 107° from both sides:
