Answer 1

Answer: b+95+34=180, b+129=180, 51

Step-by-step explanation:

b+95+34=180 works because the angles add to form a straight angle.

From this, we can obtain b+129=180 by adding the two constants.

Subtracting 129 from both sides, we get b=51.

Find (f•g) (x) if f(x)=3x^2 and g(x)=5-x

Answers

Answer:

f(g(x))=3x^2-30x+75

Step-by-step explanation:

We want to find the value of f(x) when x is equal to g(x)

So we can substitute the value of g(x) into the f(x) equation

f(g(x))= 3(5-x)^2

f(g(x))= 3(25-10x+x^2)

f(g(x))=3x^2-30x+75

1. Which of the following shows the value of (4.3 x 10-7)(1.5 x 10-3) in scientific notation? a. 6.45 x 10-10 b. 64.5 x 10-9 C. 0.645 x 10-11 d. 645 x 10-8

Answers

The product of the expression in scientific notation is expressed as 6.45 * 10^-9

Scientific notations

The standard scientific notation is expressed as:

A * 10^n

A is any value between 1 and 10

n is any integer

Given the product

(4.3 x 10-7)(1.5 x 10-3)

= (4.3 * 1.5)(10^-7 * 10^-3)
= 64.5 * 10^-10
= 6.45 * 10^-9

Hence the product of the expression in scientific notation is expressed as 6.45 * 10^-9

A series contains 18 numbers and has a sum of 4,185. the last number of the series is 275. what is the first number? 42.5 190.0 465.0 740.0

Answers

The first term of the series if the series contains 18 numbers and has a sum of 4,185 is 190

Sequence and series

Series are sum of sequences

The formula for calculating the last term of a sequence is expressed as:

Sn = n/2(a+l)

Given the following

Sn = 4185

n = 18

l = 275

Required

first term "a"

Substitute

4185 = 18/2(a + 275)

4185 = 9(a + 275)

465 = a+ 275
a = 465 - 275
a = 190

Hence the first term of the series if the series contains 18 numbers and has a sum of 4,185 is 190

Answers

The factor of the polynomial 3x³ – 5x² – 12x + 20 is (x – 2), (x + 2), and (3x – 5). Then the correct option is D.

What is a factorization?

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The polynomial is given below.

f(x) = 3x³ – 5x² – 12x + 20

Then the factor of the polynomial will be

Bruno will spin the arrow on the spinner 2 times. what is the probability that the arrow will stop on c at least once? 19 29 13 59

Answers

The probability that the spinner will land on c at least once is 5/9

How to determine the probability?

From the complete question, the probability that the spinner will not land on c when spun twice is:

P = 4/9

Using the complement rule, the probability that the spinner will land on c at least once is:

P' = 1 - P

This gives

P' = 1 - 4/9

Evaluate

P' = 5/9

Hence, the probability that the spinner will land on c at least once is 5/9

Answers

Answer:

x=10, z=106

Step-by-step explanation:

vertical angles: 10x-26=74

10x=100

x=10

supplementary angles: 74+z=180

z=106

x=10
z=106
EXPLAINED:
To get x you would need to set the equation like this (10x-26)=74 (since 74 and the equation with the variable are parallel), then solve normally for x.

To get z you would have to know that the straight line through it equals 180 degrees so you would simply subtract 74 for 180 and there you have it you have the value of z.

The average rate of change for the interval from x = 5 to x = 6 is - 22.

What is quadratic function?

A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.

Since, the quadratic function has a vertex at (1, 2),

Hence, the equation for the function can be written in vertex form as:

⇒ y = a(x - 1)² + 2

Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola.

Let's use the point (2, 1):

1 = a(2 - 1)² + 3

1 = a + 3

a = - 2

So, the equation for the quadratic function is:

y = -2x² + 2

Now we can use this equation to find the average rate of change between x = 5 and x = 6. The value of the function at x = 5 is:

y = - 2 x 25 + 2 = - 48

The value of the function at x = 6 is:

y = -2 x 36 + 2 = - 70

The average rate of change between x = 5 and x = 6 is:

(y₂ - y₁) / (x₂ - x₁) = (- 70 - (-48)) / (6 - 1) = - 22

Therefore, the average rate of change for the interval from x = 5 to x = 6 is - 22
