f(x) = -2(x − 4^)2+ 2

The vertex is (4,2)

so the axis of symmetry is is x=4

g(x) = 5x^2− 10x + 7

h= -b/2a = 10/2(5) = 10/10 =1

The axis of symmetry is at x=1

h(x) the axis of symmetry is at x=-2

Determine the coordinator of the point<br>of intersection of lines<br>3x-2y=13 and 2y+x+1=0

finlep [7]

Answer:

(3,-2)

Step-by-step explanation:

Given equations of line

3x-2y=13

2y+x+1=0

=> x = -1 -2y

Point of intersection will coordinates where both equation have same value of (x,y)

top get that we have to solve the both equations by using method of substitution of simultaneous equation.

using this value of x in 3x-2y=13, we have

3(-1-2y) -2y = 13

=> -3 -6y-2y = 13

=> -8y = 13+3 = 16

=> y = 16/-8 = -2

x = -1 - 2y = -1 -2(-2) = -1+4= 3

Thus, point of intersection of line is (3,-2)

A section in a stained glass window is shaped like a trapezoid. The top base is 2 centimeters and the bottom base is 4.5 centime

Elza [17]

Answer:

2.8 cm

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

$A=\frac{(B+b)h}{2}$

where

B is the length of the major base

b is the length of the minor base

h is the height of the trapezoid

In this problem, the glass window has the shape of a trapezoid. We know that:

B = 2 cm is the length of the top base

b = 4.5 cm is the length of the bottom base

$A=9.1 cm^2$ is the area of the trapezoid

Solving for h, we can find the height of the stained glass window:

$h=\frac{2A}{B+b}=\frac{2(9.1)}{2+4.5}=2.8 cm$

A person filing her federal income tax return with the Single filing status had a taxable income of $79,950. According to the ta

Tom [10]

Answer:

The income that she will have left over after paying his

federal income tax = $63,775.

Step-by-step explanation:

The amount of taxable income = $79,950

So, the taxable income will be in the range from $33,950 to $82,250.

It means, there will be $4675 fixed tax and additional 25% tax on the amount over $33,950.

The amount over $33,950 = $79,950 - $33,950 = $46,000

The additional tax = 46000 × 0.25 = $11,500 ∵25% = 0.25

So, the total federal income tax will be: $11500 + $4675 = $16,175

Therefore, the income that she will have left over after paying his federal income tax = $79,950 - $16,175 = $63,775.
