whats the minimum and maximum value of f(x)=3(x+8)^2−10
Answer:
(-8,-10)
Step-by-step explanation:
Rewrite (x+8)2(x+8)² as (x+8)(x+8).
f(x)=3((x+8)(x+8))−10
Expand (x+8) (x+8) using the FOIL Method.
Apply the distributive property.
f(x)=3(x(x+8)+8(x+8))−10
Apply the distributive property.
f(x)=3(x⋅x+x⋅8+8(x+8))−10
Apply the distributive property.
Simplify and combine like terms.
Simplify each term.
Multiply x by x.
f(x)=3(x2+x⋅8+8x+8⋅8)−10
Move 8 to the left of x.
f(x)=3(x2+8⋅x+8x+8⋅8)−10
Multiply 8 by 8.
f(x)=3(x2+8x+8x+64)−10
Add 8x and 8x.
f(x)=3(x2+16x+64)−10
Apply the distributive property.
f(x)=3x2+3(16x)+3⋅64−10
Simplify.
Multiply 16 by 3.
f(x)=3x2+48x+3⋅64−10
Multiply 3 by 64.
f(x)=3x2+48x+192−10
Subtract 10 from 192.
f(x)=3x2+48x+182
The minimum of a quadratic function occurs at x=[tex]-\frac{b}{2a}[/tex] If a is positive, the minimum value of the function is f ([tex]-\frac{b}{2a}[/tex]).
Substitute in the values of aa and b.
x=−[tex]\frac{48}{2(3)}[/tex]
x=-8
Replace the variable x with −8 in the expression.
f(−8)=3(−8)2+48(−8)+182
Y=-10
Therefore, the minimum value is (-8,-10) but if it is asking for just the y-value it would be -10.

x/x+2+1/x=1
Answer:
~Senpi boi here~
Step-by-step explanation:
Multiply all terms by x and cancel:
x+2x+1=1x
3x+1=x(Simplify both sides of the equation)
3x+1−x=x−x(Subtract x from both sides)

an experiment requires the population of the bacteria to reach 2 million before the experiment can begin. The reproduction rate of the bacteria can be modeled by the exponential equation Y= 8 times 7^x. About how many hours X will it take for the bacteria population to reach 2 million?
round your answer the the nearest hour
Answer:
about 6 hours
Step-by-step explanation:
[tex]8( {7}^{x} ) = 2( {10}^{6} )[/tex]
[tex] {7}^{x} = 250000[/tex]
[tex]x = \frac{ ln(250000) }{ ln(7) } = 6.39[/tex]
The about 6 hours the bacteria population to reach 2 million.
What is exponential equation?An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.
Given that the experiment requires the population of the bacteria to reach 2 million before the experiment can begin.
The reproduction rate of the bacteria can be modeled by the exponential equation,
y = 8 × 7ˣ.
So, according to the question,
8 × 7ˣ = 2 × 10⁶
7ˣ = 250000
x ≈ 6.4
Hence the about 6 hours the bacteria population to reach 2 million.

Gabriella needs 120 meters of fence to surround a rectangular garden.
The length of the garden is three times its width, w.
How wide is the fence?
Please try to include a Screenshot with the answer
Answer:
the width is 1.5meters
Step-by-step explanation:
the perimeter of the fence is 120m
the perimeter= 3w+w+3w+w
120= 3w+w+3w+w
120= 8w
w=1.5m
Answer:
15m
Step-by-step explanation:
Well, she needs 120 meters, which means we already know the circumference (P). P is the sum of all sides.
The lenght (a) is 3 times the width(b).
a = 3b.
Which means if a is x then b is equal to 3x
Since P is the sum of all sides, P is equal to 2a + 2b or 2x + 2*3x = 2x + 6x = 8x
120 = 8x. We are now left with an equation that has one variable only, all we need to do is to divide 120 by 8 to find what x is equal to.
8x = 120
x = 120 / 8
x = 15
We know that width(a) is equal to x, so that's the answer.
Here's a solution you can write:
P = 120m
w = x
l = 3w = 3x
P = 2w + 2l
P = 2*x + 2*3x
P = 2x + 6x
P = 8x
8x = 120
x = 120 / 8
x = 15
w = x -> w = 15m

because you first do 3*4 =12 twice because there are two sides, and do 10*3 twice, and 10*4 twice, and add it all up.
so,
24+60+80=164
answer is d.
Answer:
Option D, [tex]164\ units^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the front and back
[tex]A = l * w[/tex]
[tex]A = 10\ units * 4\ units[/tex]
[tex]A = 40\ units^2[/tex]
Step 2: Determine the area of the sides
[tex]A = l * w[/tex]
[tex]A = 3\ units * 4\ units[/tex]
[tex]A = 12\ units^2[/tex]
Step 3: Determine the area of the top and bottom
[tex]A = l * w[/tex]
[tex]A = 10\ units * 3\ units[/tex]
[tex]A = 30\ units^2[/tex]
Step 4: Determine the total surface area
[tex]SA = 2(40\ units^2) + 2( 12\ units^2) + 2(30\ units^2)[/tex]
[tex]SA = 80\ units^2 + 24\ units^2 + 60\ units^2[/tex]
[tex]SA = 164\ units^2[/tex]
