Mr. Vernon's class (21 is divisible by 7 and three and thus is composite).
Fifty-five, 23+22, 50 + 5? IDK if that helps.
Answer:
B. 1/25
Step-by-step explanation:
This question asks us to find (-2), or f(x) when x is equal to -2.
We know that f(x)=5^x. We also know that we are trying to find f(-2). Therefore, we must substitute -2 in for x.
f(x)=5^x
x= -2
f(-2)= 5^-2
Negative exponents follow the rule:
x^-b= 1/x^b
Rewrite the exponent according to this rule.
5^-2=1/5^2
f(-2)= 1/5^2
Evaluate the exponent in the denominator.
5^2=5*5=25
f(-2)=1/25
f(-2) is equal to 1/25, therefore B is the correct answer.
Answer:
Area= 247 feet²
Volume= 1235 feet³
Step-by-step explanation:
A storage pod has a rectangular floor that measures 19 feet by 13 feet and a flat ceiling that is 5 feet above the floor.
Area of the floor= length*width
Length= 19 feet
Width= 13 feet
Area= 19*13
Area= 247 feet²
Volume of the pod= area*height
Height of the pod= 5 feet
Area= 247 feet²
volume= 247*5
Volume= 1235 feet³
