Answer: 122

Step-by-step explanation: Substitute the values of x and y into the expression.

$x^6+y^2 \\ \text{ is like } \\ ( )^6 + ( )^2$

"Fill in the blanks" with the numbers given for x and y.

$(1)^6+(11)^2 = 1+121=122$

Which function is equivalent to F(x)=-4(x+7)^2-6?

Gemiola [76]

$\huge\mathfrak\orange{answer}$

Simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.

$f(x) = \red{-4(x+7)^2 - 6}$

$f(x) = -4(x^2 + 14x + 49) - 6$

$f(x) = -4x² - 64x - 196 - 6$

$\underline{f(x) = -4x² - 64x - 202}$

(good luck :) and mark me brainliest if you're satisfied with my answer)

The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents t

AfilCa [17]

Answer:

Step-by-step explanation:instead, try making the subscripts and superscripts stand out:

n-1

a = a * r

n n-1

Believe me, it's worth the extra work to do this!!

Given the sequence -3, -6, -12, -24, you can easily see that the first term,

a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.

So, a = -3 and r=2.

So the formula for this geometric sequence is

n-1

a = -3*2

The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial

GREYUIT [131]

Answer:

P(0) = 7,917

Step-by-step explanation:

The population of the community is given by the following formula:

$P(t) = P(0)(1+r)^{t}$

In which P(0) is the initial population and r is the growth rate.

The initial population P0 has doubled in 5 years.

This means that

$P(5) = 2P(0)$

Which lets us find r.

$P(t) = P(0)(1+r)^{t}$

$2P(0) = P(0)(1+r)^{5}$

$(1+r)^{5} = 2$

Applying the 5th root to both sides

$1+r = 1.1487$

$r = 0.1487$

$P(t) = P(0)(1.1487)^{t}$

Suppose it is known that the population is 12,000 after 3 years.

With this, we find P(0)

$P(t) = P(0)(1.1487)^{t}$

$12000 = P(0)(1.1487)^{3}$

$1.5157P(0) = 12000$

$P(0) = \frac{12000}{1.5157}$

$P(0) = 7917$
