I need help on this problem

Mathematics
1 answer:
dolphi86 [110]3 years ago
6 0

Answer:

B

Step-by-step explanation:

Where f(x) and g(x) intersect on the x- axis the value of y is zero

Equate either of the 2 functions to 0 and solve for x

Using f(x) = 8x² - 2, then

8x² - 2 = 0 ( add 2 to both sides )

8x² = 2 ( divide both sides by 8 )

x² = \frac{2}{8} = \frac{1}{4}

Take the square root of both sides

x = ± \sqrt{\frac{1}{4} } = ± \frac{1}{2}

Hence k = \frac{1}{2} → B

(1) C = 15x + 40000 ...............because it cost $15 to produce each CD with a one-time cost of $40,000

(2) R = 59x ......................because each CD will sell for $59

(3) P = R - C → P = 59x - (15x + 40000) → P = 44x - 40000

(4) 44x = 40000 → x = 909 ........ They must sell 909 in order to break even

58+28=86.
8+8=16
5+2=7
take the 1 from 16 and add it onto the 7
1+7=8: thats the tens place.
Now we only have 6. So thats the ones place. Combine the two numbers and you get 86.

Honeydew lemons sell in a market place for $24.95 per box. One box contains 9 melons. How much would you have to pay for 17 melo
Neporo4naja [7]

Answer:

47.13 for 17 melons

Step-by-step explanation:

We can use a ratio to solve

24.95               x dollars

---------------- = ----------------

9 melons          17 melons

Using cross products

24.95 * 17 = 9x

Divide by 9

24.95 * 17/9 = x

47.127777777 = x

Rounding to the nearest cent

47.13 for 17 melons

* Can someone please help me??? *<br> * 8th-grade math *<br> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
serg [7]

Answer:

B,C

Step-by-step explanation:

So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).

Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.

A) 5²+6²=9²

25+36=81

61≠81

B) 0.25+1.44=1.69

C)49+576=625

D) 100+256≠361

E)1+4≠9
