Answer:
(-1.25, 0) or (-5/4, 0)
Step-by-step explanation:
The x-intercept is when y = 0, so let's plug 0 into the equation:
3(0) - 8x = 10
Now we use basic algebra to solve for x:
0 - 8x = 10
-8x = 10
x = -5/4 or -1.25
So the answer is (-1.25, 0) or (-5/4, 0).

Range of is [4,∞).
<u>Step-by-step explanation:</u>
Here we have , function , We need to find range of this function . Let's find out:
In the function , Let's focus on : It's a perfect square whose value will be always positive and greater then equal to zero i.e.
⇒ , So minimum value of is 0 at x=-3 . ∴
⇒
⇒
⇒
Minimum value of is 4 , And maximum value of can be ∞ as value of x can be increased . Therefore , Range of is [4,∞).
Answer:
<em>The porch is 7.35 feet off the ground</em>
Step-by-step explanation:
<u>Trigonometric Ratios</u>
The ramp, the height of the porch, and the distance from the base of both form a right triangle where trigonometric ratios can be applied.
The angle of 20° has the height of the porch H as the opposite side, and the hypotenuse is the length of the ramp.
The sine is defined as:
For our problem:
Solving for H:
Find the sine of 20° by using a calculator:
H=7.35 feet
The porch is 7.35 feet off the ground
I believe 8.23 is greater because 8.2 can be 8.20 so that’s why my answer is 8.23
