Answer:

117 cm³

Step-by-step explanation:

To calculate the volume of a Rectangular Prism, we must use the formula:

l×w×h=V.

In this case, l= 13, w= 3, and h= 3.

When these values are substituted in, we get:

13×3×3= 117 cm³

A missile is launched from the ground. Its
Softa [21]

Answer:

The height of the missile in the air after 11 seconds is 330 feet.

Step-by-step explanation:

The standard form for the quadratic function f(x)= , which is the function of the parabola model.

We are given two points.

(1, 130) and (2, 240)

Here the first coordinate represents the x (time) and the second coordinate represents h(x), which is height.

Now plug these two coordinates and find the two equations.

(1, 130), the equation is

130 = a.(1)^2 + b(1) + c, where "c" is the initial height. Which is equal to zero.

Therefore, we get

130 = a + b + 0

a + b = 130 -------(1)

Now let's form the second equation using the coordinate (2, 240)

240 =

240 = 4a + 2b -------------(2)

Now let's solve the equations (1) and (2) and find the value of "a" and "b"

a + b = 130 can be written as a = 130 - b

Here we can use the substitution method.

Now plug in a = 130 - b in the second equation, we get

240 = 4(130 - b) + 2b

240 = 520 - 4b + 2b

240 = 520 - 2b

2b = 520 - 240

2b = 280

Dividing both sides by 2, we get

b = 140

Now plug in b = 140 in a = 130 -b and find the value of a

a = 130 - 140

a = -10

Now we got a = -10 and b = 140.

We plug in a = -10 and b = 140 in the general form, we gety

h(x) =

Where c is the initial height, which is equal to 0.

h(x) =

Now plug in x = 11 seconds and find the height.

h(11) = -10(11)^2 + 140 (11)

= -10 (121) + 1540

= - 1210 + 1540

h(11) = 330 feet,

Therefore, the height of the missile in the air after 11 seconds is 330 feet

A circular cake is 360 degrees if you eat a piece that is 40 degrees of the cake, how many degrees are left in the cake?
ololo11 [35]

Step-by-step explanation:

a whole circle is 360°.

if you take away 40°, how many are left ?

that is absolutely the same as the question, when I have 15 apples and 6 are eaten, how many are left ?

well, 15-6 = 9 apples are left.

and so, 360-40 = 320° are left.

What is the length of a rectangle with a width of 10 cm and area of 120 cm???
melamori03 [73]

Answer:

12cm

Step-by-step explanation:

Width = 10 cm

Area = 120 cm²

Length = ?

Area = Length(L) × Width(W)

120cm²  = L × 10cm

L = 120cm² ÷ 10 cm = 12cm

Interpret the slope for the situation: The number of people who worked for the railroads in the United States each year from 198
marysya [2.9K]

Answer:

-6.61

Step-by-step explanation:

Unless there is more included in this problem then -6.61 is the slope. Slope is represented as m in y=mx+b. Simply substituting in the slop and y-intercept shows that m=-6.61 or the slope is -6.61.
