If B2 is changed from 7 to 9, what value will appear in C3 if C3 contains the formula =B2*2?
The value of C3 will increase with a factor of 4 because the value of B2 increased with a factor of 2 and C3 is multiplying B2 by 2.
How to find how C3 will change if it has the formula =B2*2 and B2 increased from 7 to 9Given data
B2 is changed from 7 to 9
C3 contains the formula =B2*2
Finding the increment in B2
= 9 - 7
= 2
The effect on C3
C3 = B2 * 2
C3 = 2 * 2
C3 = 4
We can therefore say that The value of C3 will increase with a factor of 4 because the value of B2 increased with a factor of 2 and C3 is multiplying B2 by 2.

The current height of the bird is:
= 15 - 6 1/3
We can write the mix fraction 6 1/3 in a proper fraction
6 1/3 = 19 / 3
= 15 - 19/3
= (45 - 19) / 3

A twelve inch candle and an 18 inch candle are lit at 6pm. The 12-in. candle burns 0.5 inches every hour. The 18 inch candle burns two inches every hour. At what time will the two candles be the same height? Let h represent the number of hours.
Answer: alright, here we go
Step-by-step explanation:
best way to represent this is linear equations, so:
y=-0.5x+12
y=-2x+18
-2x+18=-0.5+12
+0.5x +0.5x
-1.5x+18=12
-18 -18
-1.5x=-6
-x=-4
x=4
y=-2(4)+18
y=-8+18
y=10
answer: (4,10)
answer: h=4
bonus: the candles will each be ten inches tall after four hours
\Find the equation of a line that contains the points (−8,−1) and (−1,−2).
The correct answer is 1x+7y=-15.
Finding an equation in standard form for a line with the points (-8, -1) and (-1, -2) is what we're after.
Since a, b, and c are integer coefficients in standard form, a and b CANNOT equal 0 or be negative.
It is helpful to first put the line in a different form, such as slope-intercept form, which is represented by the equation y=mx+b, where m is the slope and b is the y intercept.
Let's start by calculating the slope using the equation, which can be done from two points.
(y_2-y_1)/(x_2-x_1)
x1 = -8
y1 = -1
x2 = -1
y2 = -2
Substituting the value = (-2-(-1 ))/((-1-(-8))
= -2+1/-1+8
= -1/7
Thus the slope is -1/7
y=mx+b
y=(-1/7)x+b
-1=(-1/7)(-8)+b
-1=8/7+b
-1-8/7=b
-7-8/7=b
-15/7 = b
substituting the value in equation,
y = (-1/7)x-15/7
7y=-1x-15
Thus the equation is,
1x+7y=-15

When evaluating functions, what is f(x) = x + 7
The value of the function is f(−1)=6.
A function is defined as a relation between a set of inputs having one output each.
In this problem, we are given a function f(x) = x+7 and we are asked to evaluate f(-1)
Recall that f(x) = y.
When we evaluate functions, we substitute the given x-value to find the corresponding y-value of the functionWhen evaluating functions using function notation the number in place of the "x" in "f(x)" is the number that you plug into the x of your function.
So, if f(x)=x+7 then
f(−1)=(−1)+7

Fill in the blank.
In words, the logarithm of x is
the logarithm of x ells us the value of the exponent y of 10 such that 10^y is equal to x.
What is the logarithm of x?
First, let's define the natural logarithm.
We know that the natural logarithm is the inverse of the exponential function, then:
[tex]e^{ln(x)} = x\\ln(e^x) = x[/tex]
So the natural logarithm of x tells us the value of the exponent y of e such that e^y is equal to x.
And the logarithmic function is a logarithm on base 10, which is written as:
log(x) = log₁₀(x) = ln(x)/ln(10)
If we say that this is equal to e^y for some value of y, we get:
ln(x) = ln(10)*y
If now we apply the exponential function in both sides, we get:
expo(ln(x)) = exp(ln(10)*y) = 10^y
x = 10^y
So, the logarithm of x ells us the value of the exponent y of 10 such that 10^y is equal to x.

2) [8 points] Benjamin wishes to strengthen a mixture that is 10% alcohol to
one that is 30% alcohol. How much pure alcohol should they add to 12L of
the 10% mixture?
you need to add 3.43 liters of pure alcohol to reach a concentration of 30%.
How much pure alcohol should they add to 12L of the 10% mixture?Let's define the variable x as the number of liters of the 30% that you need to use.
The concentration of the mixture then will be:
1*x + 0.1*12
Where the concentration for the x liters is 100%, because this is pure alcohol, and for the 12 liters we use a concentration of 10%.
Now, that must be equal to a mixture with a concentration of the 30%, then we can write:
x + 0.1*12 = (x + 12)*0.3
Now we just need to solve this linear equation for x.
x + 1.2 = x*0.3 + 12*0.3
x - x*0.3 = 12*0.3 - 1.2
x*0.7 = 12*0.3 - 1.2
x = (12*0.3 - 1.2)/0.7 = 3.43
This means that you need to add 3.43 liters of pure alcohol to reach a concentration of 30%.

A shipping company charges based on calculations of the volume of a rectangular box and the sum of the dimensions of the box. A square rectangular prism has a side length represented by the linear function f(x), and a height represented by the linear function g(x). Which statement describes the combined functions V(x) and S(x)? The volume function is linear but the sum function is not. The sum function is linear but the volume function is not. Both the volume function and the sum function are linear. Neither the volume function nor the sum function is linear.
The statement that describes the combined functions V(x) and S(x) is B. The sum function is linear but the volume function is not.
How to illustrate the information?It should be noted that we are given that f(x) and g(x) are linear. Due to this, the sum function S(x) is linear.
And we know the shape of our figure, so we just need to multiply the dimensions for V(x) but the product of three linear functions results in a cubic function, and we conclude V(x) is not linear.
Therefore, the statement that describes the combined functions V(x) and S(x) is that the sum function is linear but the volume function is not.

A baseball is hit from an initial height of 3 feet. The baseball reaches its maximum height of 81 feet when it is 156 feet from home plate. Write a quadratic function to represent the height of the baseball as a function of its distance from the home plate.
The quadratic function to represent the given situation is y=-(1/312)x²+x+3
A quadratic function is of the form y=g(x) where g(x) is a polynomial in x with degree 2.
The baseball is hit at a initial height of 3 feet. The baseball follows a path of a parabola.
Maximum height=81 feet
Distance from home plate =156 feet
So, (156,81) is the vertex of the parabolic path.
We know that when vertex is at (h,k) then the vertex form of the parabola is y=a(x-h)²+k
So the quadratic equation is of the form
y=a(x-156)²+81
Now the initial height is given as 3 feet.
So at x=0, y=3
Putting the values in the equation we get:
3=a(0-156)²+81
or, -78=a×156²
or, a=-(78÷156²)
or, a=-(1/312)
So the quadratic equation can be written as
y=-(1/312)(x-156)²+81
Simplifying we get : y=-(1/312)x²+x+3
The quadratic function to represent the path of the baseball is given by y=-(1/312)x²+x+3
