Multiply tvs sold by cost of the warranty:

17 x 20 = $340

Subtract the total warranty from total made and divide by number of TVs.

1360 - 340 = 1020

1020/17 = 60

He earns $60 per tv

Help quick! i can't figure it out! <br> +6p - 3q + z - 3p + 2q - z - p + 00q
ki77a [65]

Answer:

2p + 99q

Step-by-step explanation:

To simplify the expression, combine the like terms. Like terms are terms which have the same variable. Assume 00q is 100q.

6p - 3q + z - 3p + 2q - z - p + 100q

6p - 3p - p = 2p

- 3q + 2q + 100q = 99q

z - z = 0

So the expression is 2p + 99q

How many x-intercepts would the function shown below have?<br> f(x) = -5x (2x + 1)? (x² – 6)(x² + 9)
BabaBlast [244]

Step-by-step explanation:

Here we have

f

(

x

)

=

2

x

2

(

x

−

9

)

, which can be factorized as

f

(

x

)

=

2

x

2

(

x

+

3

)

(

x

−

3

)

As there is no common factor between numerator and denominator, there s no hole.

Further vertical asymptotes are

x

=

−

3

and

x

=

3

and as

f

(

x

)

=

2

x

2

(

x

)

=

1

−

x

2

, as

x

→

∞

,

f

(

x

)

→

2

, hence horizontal asymptote is

y

=

2

.

Observe that

f

(

−

x

)

=

f

(

x

)

and hence graph is symmetric w.r.t.

y

-axis. Further as

x

=

0

,

f

(

x

)

=

0

. Using calculas we can find that at

(

0

,

0

)

there is a local maxima as

d

y

d

x

=

−

36

x

(

x

−

9

)

2

and at

x

=

0

it is

0

. Further while for

x

<

−

3

and

x

>

3

, function is positive, for

−

3

<

x

<

3

function is negative.

Now take a few values of

x

say

{

,

−

,

−

and corresponding values of

GEOMETRY 10TH GRADE NEED HELP ASAP
Maru [420]

\boxed{(6, -3)}

Step-by-step explanation:

Given the ratio 5:3

and Points A and B where A is located at (-6, 3), and B is located at (26, -13).

Let point A be (x_{1}, y_{1}), and let point B be (x_{2}, y_{2}).

(-6, 3) → (x_{1}, y_{1}).

(26, -13) → (x_{2}, y_{2}).

Let 5 be n, and 3 be m.

5:3 → n:m

(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}).

To solve, just substitute these variables into the expressions of these coordinates to get the answer.

(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m}) →

(\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)}) →

(\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)}) →

(\frac{-30 + 78}{8}, \frac{15+ -39}{8}) →

(\frac{78 – 30}{8}, \frac{15 – 39}{8}) →

(\frac{48}{8}, \frac{-24}{8})

→

(\frac{6}{1}, \frac{-3}{1})

→

(6, -3).

Thus the coordinates of B are:

\boxed{(6, -3)}

A tent in the shape of a triangular prism is made using the following piece of fabric. Find the surface area of the fabric. Show
storchak [24]

Answer:

Surface area = 85.84 ft²

Step-by-step explanation:

Considering the fact that large rectangle  area = 6 x 12 = 72 ft²

Also, the two triangles area => 2(0.5 * base * height) = 2(4 x 3.46 x 0.5) = 13.84 ft²

Hence, the total surface area is

72 + 13.84 = 85.84 ft²

Therefore, the surface area of the fabric is 85.84ft²
