Answer:

Given that,

Slope of line A=2/5

We know that , slope of perpendicular line is product of slopes.

i.e. M1 • M2=-1

$m1 = \frac{2}{5} \: \:$

m2=?

Now,

$\frac{2}{5} \times m2 = - 1 \\ or \: m2 = - 1 \times \frac{5}{2} \\ \: m2 = - \frac{ 5}{2}$

Therefore, Slope of line B is -5/2.

Hope this helps..

Good luck on your assignment..

ludmilkaskok [199]

Answer: The total face value of Daniel's bonds= $3,000.

Step-by-step explanation:

Given: Daniel buys one bond each with a par value of $1,000 from Grath Oil, Ombor Medical Supplies, and Dwyn Horticulture.

Therefore, the face value for each bond = $1,000

The total number of bonds =3

Therefore, the total face value of Daniel's bonds $=3\times\$1,000=\$3,000$

Hence, the total face value of Daniel's bonds= $3,000

Given the function f(x) = -5x + 1 + 3, for what values of x is f(x) = -12?

irina1246 [14]

Answer:

$x=\frac{16}{5}$

Step-by-step explanation:

The given function is

$f(x) = -5x +1+3$

Which can be rewritten also as

$f(x) = -5x +4$

We want to find the values of x for which

$f(x) = -12$

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

$-12 = -5x + 4\\-16 = -5x\\x=\frac{-16}{-5}=\frac{16}{5}$

At the park there a pool shaped like a circle. A - shaped path goes around the pool. Its inner diameter is 18 yd and its outer d

Hoochie [10]

Answer:

46 gallons

Explanation:

First, we need to calculate the area of the path. This area can be calculated as the difference between the area of the outer circle and the area of the inner circle. The area of a circle is equal to

$A=\pi r^2$

Where r is the radius. For the outer circle, the diameter is 28 yd, so the radius is equal to

radius = diameter/2

radius = 28 yd/2

radius = 14 yd

Then, the area of the outer circle is

$\begin{gathered} A=(3.14)(14\text{ yd\rparen}^2 \\ \text{ A = \lparen3.14\rparen\lparen196 yd}^2) \\ A=615.44\text{ yd}^2 \end{gathered}$

In the same way, the radius of the inner circle is

radius = diameter/2

radius = 18 yd/2

radius = 9 yd

Then, the area is

$\begin{gathered} A=(3.14)(9\text{ yd\rparen}^2 \\ A=(3.14)(81\text{ yd}^2) \\ A=254.34\text{ yd}^2 \end{gathered}$

So, the area of the path is

Area path = 615.44 yd² - 254.34 yd²

Area path = 361.1 yd²

Now, we know that one gallon can cover 8 yd², so we can calculate the number of gallons as

$361.1\text{ yd}^2\times\frac{1\text{ gallon}}{8\text{ yd}^2}=45.14\text{ gallons}$

Therefore, the number of gallons is 46 because we need to round the result to a whole number.

Which equation can be used to find the area of the blue triangle on the left side of the trapezoid?

kondaur [170]

Answer:4.0148 rounded to the nearest thousand is 0, but if you meant rounded to the nearest thousandth, it would be 4.015 because the 8 in the ten thousandth column would cause the 4 in the thousandth column to round up to 5.
