(F*g)(x) means to multiply the two equations.

Multiply each term by each term:

2x-1 * 3x+5 =

2x * 3x + 2x*5 + (-1)*3x + (-1)*5 =

6x^2 + 10x -3x -5 =

6x^2+7x-5

Answer:

y =  ( x − 2 ) ^ 2 + 3

y =   x^2 − 4x + 7

Step-by-step explanation:

y = a ( x − h ) ^ 2 + k

where vertex is (h,k) = (4,-1)

h=4, k=-1

y = a ( x − 4 ) ^ 2 - 1

sub ( 2,3 )

3 = a (2 - 4)^2 - 1

a=1

y = 1 ( x − 2 ) ^ 2 + 3

y =  ( x^2 − 4x + 4 )  + 3

y =   x^2 − 4x + 7

Answer:

i am not to sure but i thinks it D and can you help me with mine i really need help i will give brainlest too

Step-by-step explanation:

Answer:

D) 9.8

Step-by-step explanation:

Because you use h^2 = a^2 + b^2

and yiu rearranged the equation for one of the sides to get x = square root of h^2 and b^2 and get 9.79... which rounds to 9.8

Step-by-step explanation:

I got it right

The $6.76 and $6.94 is the interval Julie can be 95% certain that the sample means will fall within option (A) is correct.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]

σ is the standard deviation

xi is each value from the data set

X is the mean of the data set

n is the number of observations in the data set.

From the central limit theorem:

σ(x) = σ/√n

The standard deviation σ = $1.25

The sample n = 180

σ(x) = 1.25/√180

σ(x) = 1.25/√1801

σ(x) = 0.0931

The lower limit = 6.85 - 0.0931 = 6.756 = 6.76

The upper limit = 6.85 - 0.0931 = 6.943 = 6.94

Thus, the $6.76 and $6.94 is the interval Julie can be 95% certain that the sample means will fall within option (A) is correct.

Step-by-step explanation:

How do you find the sum of the first 10 terms?

To sum up the terms of this arithmetic sequence: a + (a+d) + (a+2d) + (a+3d) +

Example: Add up the first 10 terms of the arithmetic sequence:

a = 1 (the first term)

d = 3 (the "common difference" between terms)

n = 10 (how many terms to add up)

What is the sum of the first 10?

The number series 1, 2, 3, 4 , 9, 10. Therefore, 55 is the sum of positive integers upto 10.

Answer:

G. 12

Step-by-step explanation:

5/10=(x+5)/(3x+3)

1/2=(x+5)/(3x+3)

Cross multiply

3x+3=2x+10

x=7

Answer:

3.9 in^2

Step-by-step explanation:

Split it up into a top rectangle and a bottom rectangle. Find the area of the top rectangle and subtract the combined area of the two quarter circles.

The area of the rectangle is 6  * 3 = 18. The area of the two quarter circles is the same as the area of one semicircle, and since the radius is 3 you can do:

3^2 * pi / 2 = 9pi/2. As a decimal this would be: 14.14.

Then, you can do rectangle - circle = 18 - 14.14 = 3.86. Rounded to the nearest tenth, this is 3.9

Answer:

x = 18.64

Step-by-step explanation:

use tan:

⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]

⇒ tan 46 = [tex]\frac{18}{x}[/tex]

tan of 46 is 1.0355

⇒ 1.0356 = [tex]\frac{18}{x}[/tex]

multiply 18 on both sides

⇒ 1.0355 x 18 = [tex]\frac{18}{x}[/tex] x 18

⇒ 18.64 = x

Step-by-step explanation:

Answer/Step-by-step explanation:

Based on the inscribed angle theorem, any inscribed angle = ½ of its intercepted arc

Thus:

✔️Inscribed angle = 57°

Intercepted arc would be: 2*57 = 114°

✔️Intercepted arc would be: 123°

Inscribed angle = ½(123) = 61.5°

✔️Intercepted arc would be: 46°

Inscribed angle = ½(46) = 23°

✔️Inscribed angle = 69°

Intercepted arc would be: 2*69 = 138°

✔️Intercepted arc would be: 155°

Inscribed angle = ½(155) = 77.5°

Answer:

Step-by-step explanation:

y = 4x + 11, and y = -2x - 1, so

4x + 11 = -2x - 1

6x + 11  = -1

6x = -12

x = -2

y = 4x+11 = 3

y = 4x + 11

y = -2x - 1

4x + 11 = -2x - 1

4x + 2x = -1 - 11

6x = -12

x = -12/6

x = -2

y = 4x + 11

y = 4(-2) + 11

y = -8 + 11

y=3
