80% = 80/100 = 0,8
0,8 x 11 = 8,8
I not sure whatu mean by x is less than -7 on a graph.... but if u are wondering if x is less than -7 on a graph then yeah
Answer:
you can find a radius through its volume and height. Multiply the volume by 3. For example, the volume is 20. Multiplying 20 by 3 equals 60

Answer:
a. attached graph; zero real: 2
b. p(x) = (x - 2)(x + 3 + 3i)(x + 3 - 3i)
c. the solutions are 2, -3-3i and -3+3i
Step-by-step explanation:
p(x) = x³ + 4x² + 6x - 36
a. Through the graph, we can see that 2 is a real zero of the polynomial p. We can also use the Rational Roots Test.
p(2) = 2³ + 4.2² + 6.2 - 36 = 8 + 16 + 12 - 36 = 0
b. Now, we can use Briott-Ruffini to find the other roots and write p as a product of linear factors.
2 | 1 4 6 -36
1 6 18 0
x² + 6x + 18 = 0
Δ = 6² - 4.1.18 = 36 - 72 = -36 = 36i²
√Δ = 6i
x = -6±6i/2 = 2(-3±3i)/2
x' = -3-3i
x" = -3+3i
p(x) = (x - 2)(x + 3 + 3i)(x + 3 - 3i)
c. the solutions are 2, -3-3i and -3+3i
It takes 7.5 cups of milk to make 1 stick of butter.
Step-by-step explanation:
Given,
Cups of milk used = 30 cups
Sticks of butter made = 4
Unit rate describes how many units of one quantity corresponds to 1 unit of other quantity.
We will find unit rate per butter stick.
Unit rate per butter stick =
Unit rate per butter stick =
