Mathematics

Reil [10]4 years ago
3 0

Answer:

Each vehicle received \frac{3}{20} of the total capacity of the storage tank

Step-by-step explanation:

we know that

To find out what part of the total capacity of the storage tank that each vehicle received, divide three fourths by five

so

\frac{(3/4)}{5}=\frac{3}{20}

therefore

Each vehicle received \frac{3}{20} of the total capacity of the storage tank

Quotient of 1+i/3+4i?
NISA [10]

Answer:

\dfrac{7}{25} - \dfrac{1}{25}i

Step-by-step explanation:

I assume you are asking

\dfrac{1 + i}{3 + 4i}

although what you wrote means this

1 + \dfrac{i}{3} + 4i

Back to what I think is your problem:

\dfrac{1 + i}{3 + 4i} =

= \dfrac{1 + i}{3 + 4i} \times \dfrac{3 - 4i}{3 - 4i}

= \dfrac{(1 + i)(3 - 4i)}{(3 + 4i)(3 - 4i)}

= \dfrac{3 - 4i + 3i - 4i^2}{9 - 16i^2}

= \dfrac{3 - i + 4}{9 + 16}

= \dfrac{7 - i}{25}

= \dfrac{7}{25} - \dfrac{1}{25}i

A scalene triangle has the lengths 6, 11, and 12. Keyla uses the law of cosines to find the measure of the largest angle. Comple
ss7ja [257]

Answer:

Y\approx 84^\circ $(to the nearest angle)

Step-by-step explanation:

The lengths of the sides of the scalene triangle are 6, 11, and 12.

We want to use the law of cosines to find the largest angle.

Note that the largest angle is always opposite the largest side.

Therefore:

1. 12^2 = 11^2 + 6^2-2(11)(6)\cos(Y) \\\\2. 144 = 121 + 36-(132)\cos(Y) \\\\3. 144 = 157 - (132)\cos(Y) \\\\4. -13 = -(132)\cos(Y)\\\\\\5. \cos(Y) = \dfrac{-13}{-132} \\\\6. Y = \arccos \left ( \dfrac{13}{132}\right)\\\\7. Y=84.35^\circ\\\\8. Y\approx 84^\circ $(to the nearest angle)

The largest angle is 84 degrees to the nearest angle.

Someone help me please
vladimir1956 [14]

Step-by-step explanation:

Hi,

You will have to move the pre-image 15 units to the right. You're also going to have to flip the image horizontally (kind of like flipping it across the x-axis) and after that, you're going to have to flip it so that it's facing the left side.

1) 15 units right

2) Flip-up

3) Flip to the left

Hope this helps :)
