ANSWER: 18 blue ribbons and 12 red ribbons

Step-by-step explanation:

for every 3 blue ribbons there is 2 red ones

so if we add 3+2 that is 5 then divide 30 by 5 would be 6 and then separate back into basic numbers so there would be 6 threes and six twos so 18 and 12.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

Luden [163]

We are given this function:
$y=8700* (1.04)^{4}$

8700 is the initial amount.
1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.
1.04 * 100% = 104%
Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.
In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.
104% - 100% = 4%
This would be our solution if we don't have an exponent.

We have exponent so first step is to calculate the number and then we repeat the steps from above.
$1.04^{4} = 1,16985856$
1,16985856 * 100% ≈ 116,99%
116.99% - 100% = 16.99%
So, final solution is growth of 16.99%

Find the value of c so that (x+2) is a factor of the polynomial p(x). p(x)=4x^3+cx^2+x+2

Wittaler [7]

Answer:

c = 8

Step-by-step explanation:

Use synthetic division here; it's the fastest approach.

Given that (x + 2) is a factor, take -2 and use this as the divisor in synthetic division:

-2 4 c 1 2

-8 (-2c+ 16) (4c-34)

---------------------------------------------

4 (c - 8) (-2c + 17) 4c - 32

The remainder, 4c - 32, must equal zero if (x + 2) is a factor.

Then 4c - 32 = 0, and c = 8
