Answer:
The price elasticity of demand is calculated as the percentage change in quantity divided by the percentage change in price.
X=8
Explanation:
f(x)=x^2-16x+64+(x-8)^2
You see there is a double x- intercept by the 8. So the parabola is tangent to the x axis. So x=8 f(x)=0

Answer:
5
Step-by-step explanation:
sum the parts of the ratio, 3 + 4 = 7 parts
Divide the number of students by 7 to find the value of one part of the ratio
35 ÷ 7 = 5 ← value of 1 part of the ratio, then
3 parts 3 × 5 = 15 ← number of boys
4 parts = 4 × 5 = 20 ← number of girls
20 - 15 = 5
There are 5 more girls than boys
Answer:
55.2° ≤ c ≤ 55.8°
Step-by-step explanation:
We know a + b + c = 180
Let's take the smallest value of a and b and find largest value of c:
51.3 + 72.9 + c = 180
c = 55.8
Now,
Let's take the largest value of a and b and find smallest value of c:
51.5 + 73.3 + c = 180
c = 55.2
Thus, we can say, range of c is:
55.2° ≤ c ≤ 55.8°
