1.) <1=25°, <2=155°, <4=155°
slope intercept form is: y = mx + b
m = slope
b = y-intercept
In the equation y = 1/4x + 8
m = 1/4 = slope
b = 8 = y-intercept
Answer: a
Step-by-step explanation:
did the test
Answer: D.The domain and range of the function are the same.
Step-by-step explanation: Given function f(x)=-√-x.
The given function is a square root function and we have minus sign in front of x inside square root.
A square root always defined for positive values or 0.
In order to get a positive number or 0 inside square root, let us solve the inequality:

On dividing both sides by -1, the inequality sign would get flip and we get
<h3>Domain:

</h3>
We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.
<h3>Therefore, range would also be :

.</h3><h3>Therefore, correct option is D option.</h3>
Total surface area of the triangular prism is 81.6 square m.
Step-by-step explanation:
= 3 × 2.6 + 8.2 ×9
= 7.8 + 73.8
= 81.6
- Total surface area of the triangular prism is 81.6 square m.
