The base of a triangle prism shown is an isosceles triangle having a height of H cm, and an area of 36cm squared

Alika [10]

Answer:

the value of h on the diagram is 9cm

Step-by-step explanation:

area = 1/2 * base * height

a = 1/2*b*h

36=1/2*8*h

36=4h

since the 1/2 will multiply the 8

36=4h

multiply both sides by 4

h=9cm.

To the nearest degree, what is m_A? Explain

noname [10]

Answer:

$A= 53$

Step-by-step explanation:

Given

$BC = 9,6$

$AC = 7.2$

Required: Angle A

This is calculated using:

$tan\ A = \frac{Opposite}{Hypotenuse}$

From the attachment;

$Opposite = 9.6$

$Adjacent = 7.2$

So:

$tan A =\frac{9.6}{7.2}$

$tan A =1.333$

Take arctan of both sides

$A= tan^{-1}(1.333$

$A= 53$ ----- approximated

For the function f(x)=−x^2+x−7, find f(1)

tino4ka555 [31]

Answer:

f(1) = -7

Step-by-step explanation:

Step 1: Define

f(x) = -x² + x - 7

f(1) = x = 1

Step 2: Substitute and Evaluate

f(1) = -(1)² + 1 - 7

f(1) = -1 + 1 - 7

f(1) = -7
