Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow

and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow

how many more wore red.....(210 - 90) = 120 more students wore red then yellow

For a triangle the area is given as:
A=\frac{bh}{2}

Re-arrange / solve for 'h':
h=\frac{2A}{b}

Substitute known values:
h=\frac{2(60m^{2})}{15m}

Compute:
h=\frac{120m^{2}}{15m}
h=8m

Question 5 of 6Which exponential expression is equivalent to the one below?(22• (-7))40A. 40 • (22• (-7))O B. (22) • (-7)40C. (2
zmey [24]

Okay, here we have this:

Considering the provided expression, we are going to analize which exponential expression is equivalent, so we obtain the following:

As the property of the exponent of a multiplication says that it is equal to the product of each number raised to that power. We have this:

\begin{gathered} \mleft(22\cdot\mleft(-7\mright)\mright)^{40} \\ =(22)^{40}\cdot(-7)^{40} \end{gathered}

Finally we obtain that the correct answer is the option D.

An object has a potential energy of 14 J and a mass of 17 kg , how far above the ground is the object? An object moving with a s
victus00 [196]

1. Potential Energy = mgh

h = U_g / (mg) = 14 / (17 * 9.81) = <u>0.084 m above the ground.</u>

2. Kinetic Energy = 1/2 mv^2

m = 2K_e / (v^2) = <u>2.45 kg</u>

3. U_g = mgh = (1200)(9.81)(24) = <u>282528 J</u>

4. U_g = mgh = (478)(9.81)(150) = <u>703377 J</u>

5. U_g = mgh = (100)(9.81)(12.5) = <u>12262.5 J</u>

6. h = U_g / (mg) = 14 / (17 * 9.81) = <u>0.084 m above the ground.</u>

<u />

7. m = U_g / (gh) = 1500 /  (9.81 * 35) = <u>4.37 kg</u>

Can someone please help me find the domain, range, intercepts, and asymptotes pf this function?
marishachu [46]
1) given function

y = - 2 ^ ( -x + 2) + 1

2) domain: domain is the set of the x-values for which the function is defined.

The exponential function is defined for all the real numbers, so the domain of the given function is all the real numbers.

3) x-intercept => y = 0

=> y = - 2 ^ ( -x + 2) + 1 = 0 => 2^ ( -x + 2) = 1

=> - x + 2 = 0 => x = 2

The x-intercept is x = 0

4) y-intercept => x = 0

=> y = - 2 ^ ( -x + 2) + 1= - 2 ^ ( 0 + 2)  1 = - (2)^(2) + 1 =- 4 + 1 = - 3

=> The y-intercept is - 3

5) limit when x -> negative infinite

Lim f(x) when x -> ∞ = - ∞

6) limit when x -> infinite

Lim f(x) when x - > infinite = 1

=> asymptote = y = 1

7) range is the set of values of the fucntion: y

Given that the function is strictly decreasing from -∞ to ∞, the range is from - ∞ to less than 1

Range (-∞,1)
