Mathematics

Rasek [7]3 years ago
4 0

Answer:

y= -11/7x+8

move variables to the right hand side and change its sign

-7y=-56+11x

change the signs on both sides of the equation

7y=56-11x

divide both sides by 7

y=8-11/7 x

reorder the terms and get y= -11/7x+8

The dimensions of a triangular prism are shown.
Serhud [2]

9514 1404 393

Answer:

  B.  32 square inches

Step-by-step explanation:

Each of the two triangular faces has an area of ...

  A = (1/2)bh = (1//2)(6 in)(4 in) = 12 in²

The lateral surface area is the product of the prism height (0.5 in) and the perimeter of the base.

  LA = (0.5 in)(5 in +5 in + 6 in) = 8 in²

So, the total area is the area of the two base and the lateral area:

  SA = 2A +LA

  SA = 2(12 in²) +8 in² = 32 in²

The surface area of the prism is 32 square inches.

The function f(x)=501170(0.98)x gives the population of a Texas City x years after 1995. What was the population in 1995?
galina1969 [7]

Answer:

The population of a Texas City in 1,995 was 501,170\ people

Step-by-step explanation:

we have

f(x)=501,170(0.98^{x})

we know that

The population in 1,995 is for x=0

so

substitute the value of x=0 in the function f(x)

f(0)=501,170(0.98^{0})=501,170\ people
