Answer:

D) -10

Step-by-step explanation:

We will assign g(x) to be equal to 25, and then solve for x:

25 = -3x-5

30 = -3x

10 = -x

-10 = x

So D is correct

Answer:

-10 is correct option

Step-by-step explanation:

g(x)=-3(x)-5

g(-10)=-3(-10)-5

=30-5

=25

Answer:

1. f(x)=-x^2+40x+120. Answer: it would be the same answer

2. f(x)=−x 2 +40x+120. Answer: look at the both picture

Step-by-step explanation: Hope this help :D

Both functions have the same concavity—they are both concave downward.

Let's start with the first function, f(x) = -x² + 40x + 120.

First Derivative:

f'(x) = -2x + 40

Second Derivative:

f''(x) = -2

Since the second derivative is a constant (-2), it is negative for all values of x. Therefore, the first function has a concave downward shape.

Now let's move on to the second function, f(x) = -x² + 40x + 120.

First Derivative:

f'(x) = -2x + 40

Second Derivative:

f''(x) = -2

Similar to the first function, the second function also has a constant second derivative (-2) that is negative for all values of x. Therefore, the second function also has a concave downward shape.

In conclusion, both functions have the same concavity—they are both concave downward.

Answer:

Step-by-step explanation:

This doesn't factor. Not only that, but it does not give real results. The discriminate is negative.

a = 2

b = 4

c = 10

You could divide this equation by 2

a = 1

b = 2

c = 5  

These three are smaller and easier to calculate. The answer will be the same.

x = (- b +/- sqrt(b^2 - 4*a*c ) / (2 a)

x = (-2 +/- sqrt(^2 - 4(1)*(5) ) / 2*1

x = (-2 +/- sqrt(4 - 20) ) / 2

X = (-2 +/- sqrt(-16) ) /2

x = (-2 +/- 4i ) / 2

x = ( - 1) +/- 2i

Answer: 1.39(1.006)^t

Step-by-step explanation:

The equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.

A statement that relates two unknown parameters such that one is dependent on the other is called a function.

It is given that

Initial population = 1.39 billion in 2013

Growth Rate = 0.6%

Let a represent the initial population

b is the growth rate

and 2 be the elapsed year from 2013

and let the population at any given year is P(t)

Then the equation formed is

P(t) = a * bⁿ

P(t) = 1.39 * ( 1.006)ⁿ

Therefore the equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.

Answer:

After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

Step-by-step explanation:

Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:

1/2 ^ 6 = X

0.015625 = X

1/64 = X

1/2 ^ 28 = X

0.0000000037252902984619140625 = X

1/268435456 = X

Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

45.99 yd²

Step-by-step explanation:

The square is 5 yd × 7 yd

35 yd²

The circle = 2 × pi × radius

2 × 3.14 × 3.5

21.99115 rounds to 21.98 yd²

Since it is have a circle,

21.98 yd² ÷ 2

10.99 yd²

35 yd² + 10.99 yd²

45.99 yd²

Answer:

5y - 2x = 8

Step-by-step explanation:

First off we have to find the y-intercept with : b = y-mx

[tex]b=2-(\frac{2}{5})(1)[/tex]

[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]

[tex]b=\frac{8}{5}[/tex]

now we have the point slope form

[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]

Multiply both sides by 5

[tex]5y=2x+8[/tex]

Subtract 2x from both sides

[tex]5y-2x=8[/tex]

Answer:

Step-by-step explanation:

u/4 + 9.9 = 16.9

Putting value of u = 24 in the equation

24/4 + 9.9 = 16.9

6 + 9.9 = 16.9

15.9 = 16.9

Bringing like terms on one

16.9 - 15.9 = 1

Step-by-step explanation:

u/4 + 9.9 = 16.9

Putting value of u = 24 in the equation

24/4 + 9.9 = 16.9

6 + 9.9 = 16.9

15.9 = 16.9

Bringing like terms on one

16.9 - 15.9 = 1

Answer:

113.1 cm²

Step-by-step explanation:

we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius

so first, we need to find the radius

the length of the radius is half the length of the diameter

so that means that r=d/2

r=d/2

r=12/2

r=6

therefore the length of the radius is 6

now square 6, which is the same as multiplying it by itself

6²=36

now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7  

so if we were to do 22/7 for instance,

36*22/7≈113.14

round that to 113.1

there's your answer :)
