If the measure of angle 4 is 132°, what is the measure of angle 7?

Angles 1, 3, 5, 7, 9 and 11 are corresponding while angles 2, 4, 6, 8, 10 and 12 are corresponding
angles 8 and 7 are supplementary
since 4 and 8 are corresponding, angle 4 is 132° so angle 8 would also be 132°
180-132=48
°
angle 7 would be 48

Given points A(4,5) and B(-4,11). Find the distance AB to the nearest tenth.

If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

Choice A. Work done below:
4x-1=5x-8 ( Set the opposite sides equal to each other).
4x-5x-1=-8 (Subtract 5x on both sides)
-x-1=-8 (Combine like terms)
-x=-8+1( Add 1 on both sides)
-x=-7 (Now since you have a negative sign on both sides you can cancel them)
x=7 ( Making that as your answer!!)

QUESTION POSTED AT 28/03/2020 - 12:29 PM

Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º. Scarlett's height is 1.65 meters, so the height of the dam is meters.

Answer:

Height of the dam is 45.45 meters.

Step-by-step explanation:

From the attached figure, AB is the height of dam NM is Scarlett's height. We have to find the height of the dam. NM = CB = 1.65 m

Using trigonometric equations as:

tan(26)=\dfrac{AC}{NC}

tan(26)=\dfrac{AC}{90}

AC=tan(26)\times 90

AC = 43.8 m

So, the height of the dam is AC + CB = 43.8 m + 1.65 m = 45.45 m

Hence, the height of the dam is 45.45 meter.

HELP ASAP Given s(x) = 3x - 6 and t(x) = 6 - 3x. find the simplified formula and domain for v(x)=(s/t) and w(x)=(t/s)(x)

v(x)=(s/t)
= (3x - 6) / (-3x+6)
= [3(x-2)] / [-3(x-2)] --> 3 is factored out
= 1/-1 
---> common terms are cancelled out. 
= -1 ---> This is the simplified formula.

To find the domain, we equate the denominator to 0.
-3x+6 = 0
3x = 6
x = 2
Domain: all values except 2.

w(x)=(t/s)(x)
= (-3x+6)x / (3x-6)
= [-3x(x-2)] / [3(x-2)] --> 3 is factored out
= -x --> The common terms are cancelled out. This is the simplified formula.

Solving for domain:
3x-6 = 0
3x = 6
x = 2
Domain: all values except 2.

Triangle ABD is similar to triangle ACD. AB = 10, BC = 12, BE = 4, and CD = y. Find y.

There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

Find the volume of the toy bus pictured below whose sides are 4.5 cm, 6.8 cm, and 8.2 cm (to the nearest hundredth)?

Answer:

V=250.92 cm ^3

Step-by-step explanation:

Given:  A toy bus  whose sides are 4.5 cm, 6.8 cm, and 8.2 cm.

To find: The volume of the toy bus.

solution: It is given that a toy bus has sides 4.5 cm, 6.8 cm, and 8.2 cm, then the volume of the toy bus is given as:

V=l{\times}b{\times}h

Substituting the given values in the above formula, we get

V=4.5{\times}6.8{\times}8.2

V=30.6{\times}8.2

V=250.92 cm ^3

Therefore, the volume of the toy bus is 250.92 cm ^3.

I NEED HELP PLEASE! Khalid wrote the sequence below. x-1, -2x+2, 4x-4, -8x+8 Which formula can be used to find the 10th term of the sequence? A. B. C. D.

The given sequence is x-1, -2x+2, 4x-4, -8x+8 .

Notice that this is a geometric sequence because here we have equal common ratio.

So, common ratio : r =  \frac{a_{2}}{a_{1}}

=  \frac{-2x+1}{x-1}

=   \frac{-2(x-1)}{(x-1)} Take out -2 as common factor

= -2 Cancel out x - 1.

The formula for general term of a geometric sequence is,

 a_{n} =a_{1} r^{n-1}

Where, first term:  a_{1} =x-1

We need to find the 10th term of this sequence. So, n = 10.

Next step is to plug in these values in the above formula to get the 10th term. Hence,

 a_{10} = (x -1)(-2)^{10-1}

So, A is the correct choice.
