jim wants to put carpet in 4 identical rooms. Each room is 14ft by 20.5. ft. A roll of carpet will cover 2oo ft. how many rolls
Lyrx [107]
Find the total square footage of each room. The room will be a rectangle and finding the area of a rectangle is just the length times the width

area of rectangle = lw

area of each room = 14 x 20.5 = 287 ft^2

The 4 rooms each have the same square footage.

Total square footage of all rooms = 287 x 4  = 1148 ft^2

To find how many roles of carpet are needed, divide the footage needed to be covered by the footage per carpet

1148/200 = 5.74

You can't buy 5.74 of a carpet roll, so you will need 6 rolls :)

Hope I helped

graph the function f (x) = x^2 + 4x -5. on the coordinate plane. (a) What are the x-intercepts? (b) What are the y-intercepts? (
Butoxors [25]

Answer:

a) (-5,0) and (1,0)

b) (0,-5)

c) minimum

See attached graph.

Step-by-step explanation:

To graph the function, find the vertex of the function find (-b/2a, f(-b/2a)). Substitute b = 4 and a = 1.

-4/2(1) = -4/2 = -2

f(-2) = (-2)^2 + 4(-2) - 5 = 4 - 8 - 5 = -4 - 5 = -9

Plot the point (-2,-9). Then two points two points on either side like x = -1 and x = -3. Substitute x = -1 and x = -3

f(-1) = (-1)^2 + 4 (-1) - 5 = 1 - 4 - 5 = -8

Plot the point (-1,-8).

f(-3) = (-3)^2 + 4(-3)  - 5 = 9 - 12 - 5 = -8

Plot the point (-3,-8).

See the attached graph.

The features of the graph are:

a) (-5,0) and (1,0)

b) (0,-5)

c) minimum

Find the vertex, focus, and directrix. y = 1/24(x+1)² - 3. 
Vedmedyk [2.9K]
y = \frac{1}{24}(x+1)^2 - 3\\\\y+3 =\frac{1}{24}(x+1)^2\ \ / *24\\\\ (x+1)^2 = 24(y+3)

This   is  an  equation  of  a  parabola  that  opens  upwards.

Its \ standard \ form: \\(x-h)^2=4p(y-k)\\ (h,k)=(x,y) \ coordinates \ of \ the \ vertex\\\ (h,k)=(-1,-3) \\\\axis \ of \ symmetry: \ x= -1\\ \\4p=24\ \ /:4\\p=6

focus:(h,k+p)=(-1,-3+6)=(-1,3) \\ \\directrix: \ y=k-p=-3-6=-9

what is the missing side in a right triangle if one leg measures 5 cm and the longest side measures 13 cm
Alika [10]

Answer:

<u>The missing side is 12 cm length</u>

Step-by-step explanation:

1. Let's review the information given to us to solve the case correctly:

Length of the longest side= 13 cm

Length of one leg = 5 cm

2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:

2nd leg² = Length of the longest side ² - Length of one leg²

2nd leg² = 13 ²  - 5 ²

2nd leg² = 169  -25

2nd leg² = 144

2nd leg = √144

2nd leg = 12 cm

<u>The missing side is 12 cm length</u>
