Answer:

Step-by-step explanation:

f(x) = x²-2

g(x) = 4x-2

f.g(x)= x²-2(4x-2) = x²(4x-2)-2(4x-2) = 4x³-2x²-8x+4

f.g(x) = 4x³-2x²-8x+4

If U=pi(r+h),find r when U=16 1/2 and h=2<br> solve this question by take the value of pi 22/7

I am Lyosha [343]

$U=\pi (r+h) \\\\ 16 \frac{1}{2}= \frac{22}{7}\cdot (r+2) \\\\ \frac{33}{2} : \frac{22}{7}=r+2 \\\\ \frac{\not 33}{2}\cdot \frac{7}{\not 22}=r+2 \\\\ \frac{3}{2} \cdot \frac{7}{2}=r+2 \\\\ \frac{21}{4}=r^{(4}+2^{(4} \\\\ 21=4r+8 \\\\ 4r=21-8 \\\\ 4r=13 \\\\ \boxed{r=\frac{13}{4}}$

Answer:

Patel will require more orange juice = $\frac{371}{660}$ cups

Step-by-step explanation:

Patel needs the orange juice for his family = 3 cups

He needs more orange juice = 3 cups - Sum of juice squeezed from different oranges

$=3-(\frac{13}{15}+\frac{1}{5}+\frac{9}{20}+\frac{5}{11}+\frac{7}{15})$

L.C.M. of the denominators = 660

$=3-\frac{572+132+297+300+308}{660}$

$=3-\frac{1609}{660}$

= $\frac{1980-1609}{660}$

= $\frac{371}{660}$

Therefore, amount of orange juice required more = $\frac{371}{660}$ cups

HELLO. I NEED HELP ON A HANDFUL OF QUESTIONS. PLEASE HELP.

Question 7: $3945

78,900÷100×5= 3,945

or 789,00×0.05= $3,945

Question 8: I think it may be $675.46 ( but I'm not sure)

$1010 is her annual insurance premium so to find one month we need to divide $1010 by 12

$1010÷12= $84.20

also her annual real estate tax is $938 and to find one month we need to divide this by 12 as well.

$938÷12=$78.20

and in order to find out her combined monthly payment we need to add them all together

$513.12+$84.16+$78.16= $675.46

Question 9: is False

Question 10: I don't know

Hope this helps

What is the value of d? Assume that the line is a tangent to the circle.

motikmotik

We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to $118^{0}$ .

Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

$\measuredangle x=\frac{1}{2}m \widehat{ABC}$

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

$360^{0}-118^{0}=242^{0}$

Now we will plug given values in our formula,

$d^{0}=\frac{242}{2}=121$

Therefore, the measure of d is 121 degrees.
