The first equation has no solution



The picture shows all the work I did, the reason I took a pic is because it is a little hard to explain by text, but I hope this helped you!

a triangle flower bed has one angle of 64 degrees. the other two angles are congruent to one another. what are the measures of t
Irina18 [472]

Answer:

58 degrees

Step-by-step explanation:

well we know that every angle in a tringle adds up to 180 degrees.

so we know that 64 + angle 1 + angle 2 = 180

180-64=116

and since they are congruent (same value as one another) you just divide 116 by 2 and boom!

116/2=58

both are 58 degrees

What is the midpoint of the x-intercepts of f(x)=(x-2)(x-4
NARA [144]
Well, we know that the x-intercepts are (0,2) and (0,4).  That means that the midpoint is just (0,3)

You can also use the midpoint formula:

M=( \frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})

If you thought my answer helped and was correct, please label my answer the brainliest for others to see.

Colossus Added to six flags st. Louis in 1986, the Colossus is a giant Ferris wheel. Its diameter is 165 feet, it rotates at a r
NemiM [27]

Given:

D=165 feet and the frequency of the motion is 1.6 revolutions per minute.

Solution:

The radius is half of the diameter.

The radius of the wheel is 82.5 feet.

T=\frac{1}{1.6} \text{ minutes}

As we know: \omega=\frac{2\pi}{T}

Substitute the value of T in the above formula.

\omega=\frac{2\pi}{\frac{1}{1.6}}\\\omega=3.2\pi

If the center of the wheel is at the origin then for t=0 the rest position is -a.

This can be written as:

h(t)=-a\cos(\omega t)\\h(t)=-82.5cos(32.\pi t)

The actual height of the rider from the ground is:

h(t)=\text{ Initial height from bottom}+\text{ radius}-82.5\cos(3.2\pi t)\\h(t)=15+82.5-82.5\cos(3.2\pi t)\\h(t)=97.5-82.5\cos(3.2\pi t)

The required equation is h(t)=97.5-82.5\cos(3.2\pi t).
