If g(x) = -2x+7, what is the new function defined by h(x) = g(2x^2 +1)

hammer [34]

Answer:

h(x) = - 4x² + 5

Step-by-step explanation:

To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)

h(x) = - 2(2x² + 1) + 7

= - 4x² - 2 + 7

= - 4x² + 5

Patty is 50 mi. due north of Todd. Emma is due east of Todd. Ifa line were drawn from Emma

zubka84 [21]

Answer:

Correct choice is D

Step-by-step explanation:

Consider right triangle PTE (Patty, Todd, Emma). In thistriangle PT=50 mi - the distanse between Patty and Todd, the distance between Patty and Emma PE and the distance between Emma and Todd ET are unknown. The angle PET has the measure of 40°. Then

$\sin 40^{\circ}=\dfrac{PT}{PE}\Rightarrow PE=\dfrac{PT}{\sin 40^{\circ}}=\dfrac{50}{\sin 40^{\circ}}\approx 78\ mi.$
$\tan 40^{\circ}=\dfrac{PT}{ET}\Rightarrow ET=\dfrac{PT}{\tan 40^{\circ}}=\dfrac{50}{\tan 40^{\circ}}\approx 60\ mi.$

Find the equation of a line parallel to y = 3x - 4 that passes through (-2,2).

Grace [21]

Answer:

Slope: 3.

Equation: y = 3x + 8.

Step-by-step explanation:

Lines that are parallel to each other will have the same slopes.

So, the slope of the new line will be 3.

Since we have the slope, and a set of coordinates the line passes through, we can find the equation. So far, we have y = 3x + b. x = -2, y = 2.

2 = 3(-2) + b

3(-2) + b = 2

-6 + b = 2

b = 8

So, the equation of the line will be y = 3x + 8.

Hope this helps!
