Answer:
[tex]y=8(5)^x[/tex]
Step-by-step explanation:
We want an exponential function that goes through the two points (0, 8) and (2, 200).
Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:
[tex]8=a(b)^0[/tex]
Simplify:
[tex]a=8[/tex]
So we now have:
[tex]y = 8( b )^x[/tex]
Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:
[tex]200=8(b)^2[/tex]
Solve for b. Dividing both sides by 8 yields:
[tex]b^2=25[/tex]
Thus:
[tex]b=5[/tex]
Hence, our exponential function is:
[tex]y=8(5)^x[/tex]
Answer:
[tex]y = 8(5) {}^{x} [/tex]
Step-by-step explanation:
The normal exponential function is in form
[tex]y = ab {}^{x} [/tex]
let plug in 0,8
[tex]8 = ab {}^{0} [/tex]
b^0=1
so
[tex]8 = a \times 1 = \: \: \: \: a = 8[/tex]
So so far our equation is
[tex]y = 8b {}^{x} [/tex]
So now let plug in 2,200
[tex]200 = 8b {}^{2} [/tex]
Divide 8 by both sides and we get
[tex]25 = b {}^{2} [/tex]
[tex] \sqrt{25} [/tex]
Which equal 5 so b equal 5. So our equation is
[tex]y = 8(5) {}^{x} [/tex]

Distance from the tip to the middle of the turbine = Radius of the circular turbine
Radius of the circular turbine = 32 meters
Circumference of the circular turbine = distance the turbine will travel in one revolution
We know that :
[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]
Circumference of the circular turbine :
[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]
[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]
[tex] =\tt \frac{44}{7} \times 32[/tex]
[tex] =\tt \frac{44 \times 32}{7} [/tex]
[tex] =\tt \frac{1408}{7} [/tex]
[tex]\color{plum} =\tt 201.06 \: m[/tex]
▪︎201.06 m can be roughly rounded off to 200.96.
▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m
▪︎Therefore, the correct option is (A) 200.96

Find the value of x
in the figure below
Answer:
x = 29
Step-by-step explanation:
I think this because they give you 78 degrees. The angle across from it (3x - 9) must equal 78 degrees as well. So solve as (3x - 9) = 78. 78 + 9 is 87. 87 divided by 3 is 29.

Solve the simultaneous equations.
Please help.
Answer:
the answer is x= 5 and y = 1.5
Here we have been given with two equations and we will solve them by elimination by substitution method inorder to get the value of x and y.
5x - 4y = 19 (Equation No 1)x + 2y = 8 (Equation No 2)★ From Equation No 2 :-
>> x + 2y = 8
>> x = 8 - 2y
★ In Equation No 1 :-
Substituting here the value of x which we got above as (8 - 2y).
>> 5x - 4y = 19
>> 5 (8 - 2y) - 4y = 19
>> 40 - 10y - 4y = 19
>> 40 - 14y = 19
>> -14y = 19 - 40
>> -14y = -21
>> 14y = 21
>> y = 21 / 14
>> y = 1.5
★ Finding out value of x :-
>> x = 8 - 2y
>> x = 8 - 2 (1.5)
>> x = 8 - 2 × 1.5
>> x = 8 - 3
>> x = 5

Answer:
x = 0.954
Step-by-step explanation:
We apply pythagorean to find x
(4-x)² = 1.2² + 2.8²
(4-x)² = 9.28
✓(4-x)² = ✓(9.28)²
4 - x = 3.046
- x = 3.046 - 4
- x = -0.954
x = 0.954

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month. Write and solve an equation that can be used to determine gg, the number of gigabytes of data Sofia can use while staying within her budget.
Answer:
To stay within budget, she must use 4.5 gigabytes.
Step-by-step explanation:
Giving the following information:
Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.
First, we need to establish the total cost formula:
Total cost= 58.5 + 4*x
x= number of gigabytes
Now, we isolate x:
76.5= 58.5 + 4x
18/4= x
4.5= x
To stay within budget, she must use 4.5 gigabytes.
if a number has z positive integer factors then y and 2z integer factors. true/false
Factors are simply numbers that can divide another number without leaving a remainder.
The statement that 2z is an integer factor of y is true
The statement is given as:
The factor of number y is given as z.
From the above statement, we have:
If z is a factor of y, then 2z would also be a factor of y
So we can conclude that, the claim that 2z is a factor of y is true
