Answer: 9.75 x 10^11

Step-by-step explanation:

Product means multiply so we're solving 2.5x10^-15 x 3.9x10^26.

Since multiplication can be done in any order, we can do this in two stages:

(2.5x3.9) x (10^-15x10^26)

First 2.5 x 3.9 = 9.75

Secondly we have 10^-15 x 10^26. The bases (10) are the same, so all we need to do is add the powers, -15 + 26 = 11. So 10^-15 x 10^26 = 10^11

Finally we put them back together, and have 9.75 x 10^11

What is (2,7) rotated 90% clockwise
ohaa [14]

Answer:

The required point is, (7, -2)

Step-by-step explanation:

The straight  line passing through (0,0) and (2,7) is,

y = (\frac {7 -0}{2-0}) \times x

⇒ y = 3.5x --------------(1)

Now, the straight line perpendicular to this line and passing through (0, 0) is

y = (\frac {-1}{3.5}) \times x

⇒ 7y + 2x = 0 -------------(2)

Let, (h,k) be the required point.

then, it is on the line 7y + 2x = 0

⇒7k + 2h = 0

⇒k = (\frac {-2}{7}) \times h ------------(3)

Again, distance from (0,0) of (h, k) is same as that of (2,7)

⇒ h^{2} + k^{2} = 4 + 49 = 53

⇒h^{2} \times (\frac {53}{49}) = 53 [putting the value of k from (3)]

⇒h^{2} = 49

⇒h = 7 [since, (h,k) is in 4th quadrant, so,h >0]

So, k = -2 [putting the value of h in (3)]

So, the required point is, (7, -2)

A doormat is 2 feet long. If you placed 2 doormats in a line, would they be longer than 1 yard? Explain your answer.
tangare [24]

Answer:

Yes

Step-by-step explanation:

A yard is equivalent to 3 feet. If a singular doormat is 2 feet long then two doormats placed in a line would be 4 feet long. 4 > 3 meaning they would be longer than a yard.

The remainder when p\left(x\right)=x^3-2x^2+8x+kp ( x ) = x 3 − 2 x 2 + 8 x + k by (x-2) is 19. What is the remainder when p(x)
Dafna11 [192]

Answer:

Remainder when p(x) is divided by (x+2) is -29

Step-by-step explanation:

p(x) = x^{3} - 2x^{2} + 8x + k

When p(x) is divided by (x-2), remainder is 19.

p(x - 2 = 0)  gives the remainder when p(x) is divided by (x-2)

x - 2 = 0

x = 2

p(x-2=0) = p(2) = 2^{3} - 2(2^{2}) + 8(2) + k = 19

8 - 8 + 16 + k = 19

k = 3

p(x) = x^{3} - 2x^{2} + 8x + 3

p(x + 2 = 0)  gives the remainder when p(x) is divided by (x+2)

x + 2 = 0

x = -2

p(x+2=0) = p(-2) = (-2)^{3} - 2((-2)^{2}) + 8(-2) + 3

p(-2) = - 8 - 8 - 16 + 3 = -29

Remainder when p(x) is divided by (x+2) is -29
