Answer:
g(-3) = -27
Step-by-step explanation:
g(x) = -2x² + 3x ---> g(-3)
g(-3) = -2<u>(-3)²</u> + 3(-3)
g(-3) = <u>-2(9)</u> + <u>3(-3)</u>
g(-3) = <u>-18 - 9</u>
g(-3) = -27
Hope this helps, thank you :) !!
<span>The equation that represents the product of 15 and the is 12 more than a number would be (x+12)15=y. !</span>
"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that
a = kb
We're given that a = 18 and b = 3, so that
18 = 3k ⇒ k = 6
Then when b = 5, we would have
a = 6 × 5 = 30
Answer:
x=6
Step-by-step explanation:
In a square, its angles are all 90 degrees. So, cutting a square in half into two triangles from corner to corner produces 45 degree angles on both sides. Since the triangles are now 45-45-90 triangles, we can use the rule where the hypotenuse of the triangle is equal to the square root of 2 times the length of either side. So, the side length is 6.
The mean is 73.44<span>
</span>You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!
66+81+60+72+79+83+60+92+68 = 661
661 ÷ 9 = 73.44
