If I am understanding this right, since the <em>c </em>is a variable, you'd have to solve the equation and have the variable in the and result.

the sqrt525^7 = 3359983566.19

So you'd have to simplify this and add the <em>c</em> to the end of it. Unless your work is fractions.

(I take Algebra II I should be more confident on this topic, this is just what makes the most sense)

Answer:

$5c^3\sqrt{21c}$

Step-by-step explanation:

525 = 3 * 7 * 5 * 5

$\sqrt{525c^7} =$

$= \sqrt{5^2 \times 21 \times c^6 \times c}$

$= 5c^3\sqrt{21c}$

X+1.5 (x-3)=5/2 solve pls help me it's an immediate thing I will give 20 p for it

Yuki888 [10]

X+ 1.5x - 4.5 = 5/2
2.5x - 4.5 = 5/2
2.5x = 5/2 + 4.5
2.5x = 7
x = 7/2.5

X = 2.8

Find a vector parametrization for the line with the given description. Perpendicular to the yz-plane, passes through (0, 0, 8)

Brilliant_brown [7]

Answer:

$\left\{\begin{array}{l}x=t\\ \\y=0\\ \\z=8\end{array}\right.$

$\overrightarrow{(t,0,8)}$

Step-by-step explanation:

yz-plane has the equation $x=a,$ where $a$ is a real constant. The normal vector of this plane (vector perpendicular to the plane) is

$\overrightarrow {n}=(1,0,0)$

If the line is perpendicular to this plane, then it is parallel to the normal vector, so the equation of this line is

$\dfrac{x-x_0}{1}=\dfrac{y-y_0}{0}=\dfrac{z-z_0}{0},$

where $(x_0,y_0,z_0)$ are coordinates of the point the line is passing through.

In your case, the line is passing through the point (0,0,8), so the canonical equation of the line is

$\dfrac{x-0}{1}=\dfrac{y-0}{0}=\dfrac{z-8}{0}$

Write a vector parametrization for this line

$\left\{\begin{array}{l}\dfrac{x-0}{1}=t\\ \\\dfrac{y-0}{0}=t\\ \\\dfrac{z-8}{0}=t\end{array}\right.\Rightarrow \left\{\begin{array}{l}x=t\\ \\y=0\\ \\z=8\end{array}\right.$

I’ll give brainliest to the person who answers this right. Please help!!

Charra [1.4K]

Answer:

3.43

Step-by-step explanation:

To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43

In any given week, salesman A earns $65 per sale, so his paycheck amounts to $p_A(s)=65s$ (where $0\le s\le20$ ).

Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns $p_B(s)=45s+300$ .

Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is $p_C(s)=900$ .
