step 3. t1 = (1/2)bh where b is the base and h is the height. definition of the area of a triangle.

step 4. t1 = (1/2)(3)(2) = 3ft^2.

step 5. t2 = (1/2)(3)(3) = 4.5ft^2.

step 6. r = bh where b is the base and h is the height. definition of the area of a rectangle.

step 7. r = bh = (8)(4) = 32ft^2.

POPULATION In 2000, the world population was calculated to be 6,071,675,206. The world population increases at a rate of about 1.2% annually.

Write a function that represents the world population y after x years.

A) y = 6,071,675,205(1.012)^x

B) y = 6,071,675,206(1.012)^x

C) y = 6,071,605,205(1.012)^x

D) y = 6,071,675,215(1.012)^x

PLEASE HELP!!

Answers

Answer:

B) y = 6,071,675,206(1.012)^x

Step-by-step explanation:

It appears that this question asks for an exponential model that represents the population growth. I believe you could view the equation in the form y = (initial population)(rate)^x

Since the initial population is 6,071,675,206, you could substitute that in to get y = 6,071,675,206(rate)^x

Since your rate is increasing by 1.2% (0.012 in decimal form), just convert that to decimal form (knowing that 100% = 1.0, add 0.012 to get 1.012). Substitute that in to get y = 6,071,675,206(1.012)^x

Hope that helps. Feel free to let me know if it made sense.

the graph of y = 4x^2 - 4x - 1 is shown use the graph to find estimates for the solutions of a and b

Answers

Answer:

a) -0.25 and 1.25

b) -0.5 and 1.5

Step-by-step explanation:

a) For 4x^2-4x -1 = 0

What we have to do here is to simply find he points on the x-axis in which the graph crosses it

we have this as;

approximately-0.5 and 1.5

what we are saying is that the plot crosses the x-axis at x = -0.25 and x = 1.25

ii) what we have to do here is to find the point at which y = 2

After finding this point, we trace it to the plot sideways, before we trace to the x-axis

By tracing, we have the crossing on the x-axis at these points at -0.5 and 1.5

The distance between point Q and point P is 6 1/2 units .Which number could represent point Q?please help me

Answers

Answer:

[tex]Q =2\frac{1}{2}[/tex] or [tex]Q =- 10\frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]P = -4[/tex] --- missing from the question

[tex]Distance = 6\frac{1}{2}[/tex]

Required

Determine the possible value of Q

The distance can be calculated using absolute function as:

[tex]Distance = |Q - P|[/tex]

Substitute values for distance and P

[tex]6\frac{1}{2} = |Q - (-4)|[/tex]

[tex]6\frac{1}{2} = |Q +4|[/tex]

The absolute function can then be split as:

[tex]6\frac{1}{2} = Q + 4[/tex] or [tex]-6\frac{1}{2} = Q + 4[/tex]

Make Q the subject in both cases:

[tex]Q = 6\frac{1}{2} - 4[/tex] or [tex]Q = -4 - 6\frac{1}{2}[/tex]

[tex]Q =2\frac{1}{2}[/tex] or [tex]Q =- 10\frac{1}{2}[/tex]

36 + b^2 = 144

b^2 = 108

b = 10.4

Let me know if this helps!

Answer

10.4

Step-by-step explanation:

pagathorium theorem, A^2 + B^2 = C^2. You have the C and one length, the other can be found. So 6^2 + B^2 = 12^2. Then you have 36 + B^2 = 144. You use simple algrebra to solve the rest. 144-36 is 108. Now it's B^2 = 108. The opposite of squared is sqare root. So now you can have B all along (Missing side) with the answer ebing B = 10.392 or rounded 10.4

Slope of a line is :-
