8 0

Answer:

x =28

Step-by-step explanation:

We have similar triangles, so we can use ratios

12           8

------    = ----------

12+30     x

Using cross products

12x = 8*(42)

12x = 336

Divide by 12

12x/12 = 336/12

x =28

Which binomial is not a devisor of x^3-11x^2+16x+84?
viktelen [127]
<span>dividend x3 - 11x2 + 16x + 84 - divisor * x2 x3 - 7x2 remainder - 4x2 + 16x + 84 - divisor * -4x1 - 4x2 + 28x remainder - 12x + 84 - divisor * -12x0 - 12x + 84 remainder 0 Quotient : x2-4x-12 Remainder: 0 Step-1 : Multiply the coefficient of the first term by the constant 1 • -12 = -12 Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -4 . -12 + 1 = -11 -6 + 2 = -4 That's it Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 2 x2 - 6x + 2x - 12 Step-4 : Add up the first 2 terms, pulling out like factors : x • (x-6) Add up the last 2 terms, pulling out common factors : 2 • (x-6) Step-5 : Add up the four terms of step 4 : (x+2) • (x-6) Which is the desired factorization Final result : (x + 2) • (x - 6) • (x - 7)</span>

Kristen gets home from work at 5:34 p.m. Kristen's dinner is ready at 5:51 p.m.
bazaltina [42]

Answer:

1,020 seconds

Step-by-step explanation:

we know that

To find out how many seconds after Kristen gets home is her dinner ready, subtract the time Kristen gets home from the time Kristen's dinner is ready

so

5:51 p.m-5:34 p.m=17 min

Remember that

1\ min=60\ sec

Convert minutes to seconds

17\ min=17(60)=1,020\ sec

There are currently 4,000 Rhinos left in the world and they are going extinct at a rate of 3.7% each year. How many Rhinos will
cupoosta [38]

Answer:

2744 Rhinos will be left after 10 years

Step-by-step explanation:

This question has to do with exponential decay rate. We solve this using the formula:

P(t) = Po(1 - r)^t

Where P(t) = Amount left after t years

Po = Initial amount

r = Decay rate = 3.7% = 0.037

t = time in years = 10 years

P(t) = 4000(1 - 0.037)¹⁰

P(t) = 4000 × 0.963¹⁰

P(t) = 4000 × 0.6859032667003232

P(t) = 2743.6130668

Approximately = 2744 Rhinos will be left after 10 years
