Which of the following functions is not a linear function?

1 answer:

6 0

The graph of a linear function is a line

A)f(x) = -2 line

B)f(x) = x - 2 line

C)f(x) = 2x line

D)f(x) = x² parabola

So, D)f(x) = x² is not a linear function

on a blueprint, the area of a tennis court is 16.25cm². a) if the scale on the blueprint is 1cm: 4m, what is the actual area of

Mars2501 [29]

Step-by-step explanation:

so,

1cm : 4m

that means the factor is 1/400 (as 1 m = 100 cm).

also to remember : 1 m² = 100cm×100cm = 10,000 cm²

the area of a rectangle is

length × width

if both dimensions are shortened by a factor (1/400) in our case :

length×1/400 × width×1/400 =

= length × width × 1/400² = length × width × 1/160,000

that means the area of the actual tennis court is

160,000 times the area of the blueprint picture :

160,000 × 16.25 = 2,600,000 cm² = 260 m²

we now know that the actual length of the tennis court is 400 times the length of the blueprint length :

400 × 6.25 = 2,500 cm = 25 m

Help please worth 30

Rasek [7]

Answer:

A) AA postulate; 18

Step-by-step explanation:

Due to the similar triangles, we can set up the proportion and solve for x

8/(8+4) = 12/x

8/12 = 12/x

8*x = 12*12 ... cross multiply

8x = 144

x = 144/8

x = 18

Find MO and PR ............................................................

ddd [48]

MO = 12 and PR = 3

Solution:

Given $\triangle M N O \sim \Delta P Q R$ .

Perimeter of ΔMNO = 48

Perimeter of ΔPQR = 12

MO = 12x and PR = x + 2

If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of perimeter of the triangles.

$$\Rightarrow \frac{\text{Perimeter of }\triangle MNO}{\text{Perimeter of }\triangle PQR} =\frac{MO}{PR}$

$$\Rightarrow \frac{48}{12} =\frac{12x}{x+2}$

Do cross multiplication.

$$\Rightarrow 48({x+2})= 12(12x)$

$$\Rightarrow 48x+96= 144x$

Subtract 48x from both sides.

$$\Rightarrow 48x+96-48x= 144x-48x$

$$\Rightarrow 96= 96x$

Divide by 96 on both sides, we get

⇒ 1 = x

⇒ x = 1

Substitute x = 1 in MO an PR.

MO = 12(1) = 12

PR = 1 + 2 = 3

Therefore MO = 12 and PR = 3.

You are running a concession stand at a basketball game. You are selling hot dogs and sodas. Each hot dog costs $1.50 and each s

nikklg [1K]

Answer:

35 hotdogs and 52 sodas sold.

Step-by-step explanation:

x = the number of hotdogs sold, x>0

y = the number of sodas sold, y>0

At the end of the night you made a total of $78.50:

1.50x + 0.50y = 78.50

You sold a total of 87 hotdogs and sodas combined:

x + y = 87

We have the following system of equations:

1.50x + 0.50y = 78.50

x + y = 87
