Answer: 3cm
Explanation:
We can use Pythagorean’s theorem to find that other side:
a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3
Therefore, the other side is 3cm
C. Plug in 0 into the equation
y = (0)^2 + 10
y = 10
It would be (0,10)
Answer:
The total ticket sale value is 2500 because 5% is 1/20 of the total amount, so to find the total value of ticaket sales you multiply by 20 to get the total value of 2500.
Step-by-step explanation:
Answer:
y = 3.584
Step-by-step explanation:
Given
Variation = Inverse Proportional
When y = 7, x = 4
Required
Find y when x = 5
First, we need to represent the variation.
y varies inversely proportional to x³
This implies that
y ~ 1/x³
Convert variation to equation
y = k/x³
Make k the subject
k = x³y
When y = 7, x = 4
This gives:
k = 4³ * 7
k = 64 * 7
k = 448
To determine the value of y when x = 5;
We make use of y = k/x³
Substitute 5 for x and 448 for k
y = 448/5³
y = 448/125
y = 3.584
