The amount of wrapping paper he use is 62.4 square inches

<h3>How to calculate the surface area of a prism</h3>

The formula for calculating the total surface area is expressed as:

Area = 4(area of triangle)

Find the area of the triangle

A = 0.5(6)(5.2)

A =3(5.2)

A = 15.6 square inches

TSA = 4(15.6)
TSA = 62.4 square inches

Hence the amount of wrapping paper he uses is 62.4 square inches

Use the graph to estimate the height of a jugglers ball that has been in the air for 1.5 seconds

strojnjashka [21]

Answer:

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Step-by-step explanation:

we are given height equation as

$h=-16t^2+25t+5$

where

h is the height in feet of a Juggler's ball after t seconds

now, we can plug t=1.5

$h=-16(1.5)^2+25(1.5)+5$

we can solve for h

$h=42.5-16\cdot \:1.5^2$

$h=42.5-36$

$h=6.5$

So,

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Determine which of the following ordered pairs satisfies the given system of equations.

alekssr [168]

Answer:

(-3,2)

Step-by-step explanation:

1) -2x+y=8

you need to leave the Y alone on one side. Then, the term -2x goes to the other side with its opposite sign which is +.

y=8+2x

2) y=2x/(5-8)

3) 8+2x=2x/(5-8)

now, you need the x value. for that, you need to leave x alone on one side.

8+2x=2x/(-3)

8+2x=-(2/3)x

8=-(2/3)x-2x

8=-(8/3)x

8/-(8/3)=x

-3=x

4) you now have the x value. you need the y value. for that, replace the x in one of the given equations. let´s use the 1st equation.

-2x+y=8

y=8+2x

y=8+2*(-3)

y=2

result:

x= -3

y=2

A rectangular field has an area of 1764 square meters. The width of the field is 13 meters more than the length. What is the per

sveticcg [70]

Answer:

170m

Step-by-step explanation:

The answer to the above question is letter d which is 170 m. To get the 170 m, kindly check the below solution:

x^2 + 13x = 1764 so x = -49 and 36, we take 36 as its the positive value. And the other side is 49. Now use 2(l+b) to find perimeter. You get (36+49)*2 = 170

Answer:

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

$x_{vertex}= -b/2a$

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

$f(-13/4)= -9/8$

Then your expression for this quadratic should be:

$f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})$

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one
