Hey there!

b^2 + 5b - 5

= -6^2 + 5(-6) - 5

= -36 + (-30) - 5

= -66 - 5

= -71

Therefore, your answer is: -71

Good luck on your assignment and enjoy your day!

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height above ocean measured in f
lbvjy [14]

Answer:

480 feet.

Step-by-step explanation:

We are told that the function h(t)=-16t^2+16t+480 models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.

To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.

Upon substituting t=0 in our function we will get,

h(0)=-16(0)^2+16*0+480

h(0)=-0+0+480

h(0)=480

Since, the function gives Jason's height above ocean in feet, therefore, the cliff was 480 feet high.

If the dimensions of a pentagonal prism are quadrupled, then the surface area of the prism is multiplied by eight.
Lubov Fominskaja [6]

Answer:

false

Step-by-step explanation:

the relationship between lengths/dimensions and areas is that areas are created by multiplying 2 dimensions.

when you quadruple (×4) the dimensions, then the areas are growing with the square of the factor (×4×4 = ×16), because the factor goes twice into the multiplication : one time for every dimension involved.

so, quadrupling the dimensions would multiply the areas by 16.

Steve bought a new graduated cylinder for his chemistry class.It holds 1,058.75 of liquid. If the cylinder has a radius of 5.5 c
patriot [66]

Answer:

35 cm

Step-by-step explanation:

volume of cylinder = πr²h

πr²h = 1058.75π

Divide both sides by π.

r²h = 1058.75 cm³

r = 5.5 cm

Substitute r² with (5.5 cm)².

(5.5 cm)²h = 1058.75 cm³

h = 1058.75/30.25 cm

h = 35 cm
