Answer:

0.44

Step-by-step explanation:

This is a right angled triangle, so it yields:

$\cos \angle V = \frac{adjacent}{hypotenuse}$

The value of <em>adjacent </em>is 39.

We will use the Pythagorean rule to obtain the length of hypotenuse:

$hypotenuse^2 = 39^2 + 80^2\\hypotenuse^2 = 1521 + 6400\\hypotenuse^2 = 7921\\hypotenuse = \sqrt{7921}\\hypotenuse = 89$

Now we can insert that into $\cos \angle V$ :

$\cos \angle V = \frac{39}{89} =0.44$

Find the coordinates of the midpoint HX. H (5 1/2, -4 3/4), X (2 1/4, 1 1/4)

Fiesta28 [93]

Answer:

(3 7/8, -1 3/4)

Step-by-step explanation:

The midpoint is the average of the end point coordinates:

((5 1/2, -4 3/4) +(2 1/4, 1 1/4))/2

= (7 3/4, -3 1/2)/2 = (3 7/8, -1 3/4)

Y = (x)^(1/9)*Find f(x) when x=(1/2)Round your answer to the nearest thousandth.

Verizon [17]

We are given a function f ( x ) defined as follows:

$y=f(x)=x^{\frac{1}{9}}$

We are to determine the value of f ( x ) when,

$\times\text{ = }\frac{1}{2}$

In such cases, we plug in/substitue the given value of x into the expressed function f ( x ) as follows:

$y\text{ = f ( }\frac{1}{2}\text{ ) = (}\frac{1}{2})^{\frac{1}{9}}$

We will apply the power on both numerator and denominator as follows:

$f(\frac{1}{2})=\frac{1^{\frac{1}{9}}}{2^{\frac{1}{9}}}\text{ = }\frac{1}{2^{\frac{1}{9}}}$

Now we evaluate ( 2 ) raised to the power of ( 1 / 9 ).

$f\text{ ( }\frac{1}{2}\text{ ) = }\frac{1}{1.08005}$

Next apply the division operation as follows:

$f\text{ ( }\frac{1}{2})\text{ = }0.92587$

Once, we have evaluated the answer in decimal form ( 5 decimal places ). We will round off the answer to nearest thousandths.

Rounding off to nearest thousandth means we consider the thousandth decimal place ( 3rd ). Then we have the choice of either truncating the decimal places ( 4th and onwards ). The truncation only occurs when (4th decimal place) is < 5.

However, since the (4th decimal place) = 8 > 5. Then we add ( 1 ) to the 3rd decimal place and truncate the rest of the decimal places i.e ( 4th and onwards ).

The answer to f ( 1 / 2 ) to the nearest thousandth would be:

$\textcolor{#FF7968}{f}\text{\textcolor{#FF7968}{ ( }}\textcolor{#FF7968}{\frac{1}{2})}\text{\textcolor{#FF7968}{ = 0.926}}$

What is the FDP of 0.3

exis [7]

Answer:

0.3 = 3/10 = 30%

Step-by-step explanation:

The reading of the number as "three tenths" tells you how to write the fraction:

0.3 = 3/10

You can also express the same value in hundredths. Of course /100 is just a long way to write %, so ...

0.3 = 0.30 = 30/100 = 30%

0.3 = 3/10 = 30%

Find the volume of a prism whose area of base is 44cmsquare and height is22cm

vovangra [49]

For this problem, you can use the volume of a prism equation:
V=Bh
Where B is the area of the base and h is the height.

So to solve this problem, all you have to do is mutiply 44 square cm by 22 cm.
44 square cm • 22 cm = 968 cubic cm
