Answer:
Which Question?
Step-by-step explanation:
Answer:
2) 360 square inches
Step-by-step explanation:
First of all we have to verify that the base triangle is a right triangle
For this we use Pythagoras
h² = l1² + l2²
13² = 12² + 5²
169 = 144 + 25
169 = 169
Equality is fulfilled by what is a right triangle
Now we need to calculate the area of the triangle
a = (12 in * 5 in) / 2
a = 60in² / 2
a = 30in²
Now we have to calculate the 3 areas of the rectangles
a1 = 10in * 13 in
a1 = 130in²
a2 = 10 in * 12 in
a2 = 120in²
a3 = 10 in * 5 in
a3 = 50in²
Now we must add all the calculated areas and the triangle 2 times
a1 + a2 + a3 + 2a =
130in² + 120in² + 50in² + 2 * 30in²
360in²
The surface area of the prism is 360in²
The point (a,b) is (5,7) . Therefore, the equation of the line is y=7
Answer:
1)
At Bombinoes, if he delivers 10 pizzas, he will make $81. y = 2.50x + 56
At Little Squeezers, if he delivers 10 pizzas, he will make $78. y = 3x + 48
At Pizza Tent, if he delivers 10 pizzas, he will make $79.50. y = 2.75x + 52
2)
Little Squeezers would pay him the most if he delivered 20 pizzas. They would pay him a total of $108.
Step-by-step explanation:
Answer:
The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.
Thus, domain of f(x): x∈R = range of f¯¹(x)
and range of f(x): x∈R =domain of f¯¹(x)
