D^2 = (x2-x1)^2 + (y2-y1)^2

D =sqrt((10+5)^2 + (10-2)^2)

D P SQRT(15^2 + 8^2)

D = sqrt(225 +64)

D= sqrt(289)

D = 17

The distance is 17

At what point does the graph of y=9x(x is exponent) cross the y-axis?

uysha [10]

Answer:

-The graph crosses the y-axis at the point (0,0)

None of the given options is correct

A graph crosses the y-axis at the point (0,y).This means that the graph will cross the y-axis when x-=0

To find the point where the graph crosses the y-axis,substitute x=0 into the given equation y-9x

substitute x=0 into the equation y-9x to find the corresponding value of y

That is,

y=9(0)

y=0

therefore the graph crosses the y-axis at the point (0,0)

The drama club is selling short-sleeved shirts for $5 each, and long-sleeved shirts for $10 each. They hope to sell all of the s

blagie [28]

Answer:

150 short-sleeved shirts
100 long-sleeved shirts

Step-by-step explanation:

Let S and L represent the numbers of short- and long-sleeved shirts ordered.

The expected earnings were ...

5S +10L = 1750

The number sold was ...

(1/3)S + (1/2)L = 100

We can multiply the first equation by 1/5 and the second equation by 6 to put the equations into standard form:

S +2L = 350
2S +3L = 600

Subtracting the second equation from twice the first gives ...

2(S +2L) -(2S +3L) = 2(350) -(600)

L = 100 . . . . . . simplify

2S +3(100) = 600

S = 150

150 short-sleeved and 100 long-sleeved shirts were ordered.

Answer:

2.8¢, true

Step-by-step explanation:

The value of copper in a penny is reportedly about ...

(0.95 × 3.11 g)×(1 oz)/(28.35 g)×($0.27/oz) ≈ $0.028

Today, the value of the copper in a pre-1982 penny is about 2.8¢, more than double the value of the penny as legal tender.

The claim is true.
