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

Maria will spin the arrow on the spinner 2 times. What is the probability that the arrow will stop on the same letter twice? A. 1/9 B. 2/9 C. 1/3 D. 5/9

Answer:

probability that the arrow will stop on the same letter twice = \frac{1}{3} (c).

Step-by-step explanation:

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = \frac{number \ of \ favorable\ outcome}{Total \number\ of \possible \outcome}.

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6.  Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability =  \frac{2}{6}.

Probability =  \frac{1}{3}.

Therefore,  probability that the arrow will stop on the same letter twice = \frac{1}{3} (c).

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.
