Answer:

t = 1.94 seconds

Step-by-step explanation:

we have to solve the following polynomial equation:

-16t² + 60 = 0

16t² = 60

t² = 60/16 = 3.75

t = √3.75 = 1.936491673 seconds

the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option

the area of a rectangle is (y^2-8y+15) square inches. which expression represents a possible length? A. (y+5) B. (y-15) C. (y-2)
Pani-rosa [81]
D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.

Which is the equation of the graphed line written in standard form? y = x x – y = 0 x – y = 0 y = x
Serhud [2]

Answer:

The equation of the graphed line written in standard form is:x-y=0

Step-by-step explanation:

we know that for graphing lines the equation of a line must be in standard form.

the standard form of a line is given by ax+by=c where a,b,c are some real numbers.

hence, in the given question for graphing our line we must use the equation x-y=0 because on comparing it to the general equation of the line ax+by=c we have here a=1, b=-1 and c=0.

therefore the standard form is: x-y=0

Answer:

Volume of triangular prism = 216 in³

Step-by-step explanation:

Given:

Length of prism = 9 in

Height of prism = 6 in

Base of prism = 8 in

Find:

Volume of triangular prism = ?

Computation:

⇒ Volume of triangular prism = 1/2[lbh]

⇒ Volume of triangular prism = 1/2[9 in × 8 in × 6 in]

⇒ Volume of triangular prism = 1/2[432 in³]

⇒ Volume of triangular prism = 216 in³
