Which logarithmic equation is equivalent to the exponential equation below?
ea = 35
A. log35 2 = e
B. In 35 = a
c. log235 = 2.5
D.. In a = 35
Answer:
B
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]e^{a}[/tex] = 35, then
[tex]log_{e}[/tex] 35 = a, that is
ln35 = a → B

5 people visited SmashBurger. Each person bought a hamburger (h) and a bottle of water (w). Write an expression that shows the amount of hamburgers and bottles of water were purchased.
Answer:
Total amount of hamburgers and bottles of water = 5 h + 5 w = 5 (h + w)
Step-by-step explanation:
Since each person in the group of 5 people bought a hamburger (h), and a bottle of water (w), we can write for the total of hamburgers plus bottles of water:
Total = 5 h + 5 w = 5 (h + w)
What is the domain of the function y = Vx+6 - 7?
If you were to plug x = -6 into the equation, you'd find the x+6 portion turns to 0. Any smaller x value is not allowed because x+6 would be negative. We cannot take the square root of a negative value to get some real number.
Put another way, solving [tex]x+6 \ge 0[/tex] leads to [tex]x \ge -6[/tex]
In terms of transformations, [tex]y = \sqrt{x}[/tex] becoming [tex]y = \sqrt{x+6}[/tex] means the graph has been shifted 6 units to the left. The original domain [tex]x \ge 0[/tex] becomes [tex]x \ge -6[/tex], as the domain has also shifted the same 6 units.
Visually, the left most point on the graph will directly determine the smallest domain value. The domain is the set of all allowed x inputs.
The -7 at the end does not affect the domain at all. We can replace it with anything you want, and the domain will still be the same. This value affects the range only.

A. (x + 7)^2 + (y - 7)^2 = 10.
This is the equation of a circle.
It is NOT a function
One to many correspondence.
B. y = x^2 + 2x - 3

An airplane approaches an airport. At a certain time, the plane is 1020m
high. Its angle of elevation measured from the airport is 20.5 degrees.
How far is the plane from the airport to the nearest meter? *
A-2728
B-2913
C-1089
D-3
Answer:
2728.11m
Step-by-step explanation:
The height of the plane is 1020m
The airport makes an angle of elevation of 20.50° with the plane
The distance of the plane from the airport = ?
See attached document for better illustration of the position of the plane and airport
Using SOHCAHTOA,
tanΘ = opposite/ adjacent
θ = 20.50°
opposite = 1020m
adjacent = ? = x
Tanθ = opposite/ adjacent
Tan20.50 = 1020 / x
X = 1020 / tan20.50
X = 1020 / 0.37388
X = 2728.11m
The distance of the plane from the airport is 2728.11m

What are some good note for Notes for Median and mean
Answer:
To find the Median arrange the data in order from least to greatest then find the middle number. To find the middle number cross of one from the front and one from the bcak. If there are 2 numbers left in the middle add those numbers together and them divided the sum by 2.
The mean is the average of the numbers. It is easy to find. First, add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Step-by-step explanation:
a company makes cones out solid foam. each cone has a height of 12 inches, and it's base has a diameter of 3 inches. how much foam is needed to make 150 cones
Solid foam indicates that the cones are made purely out of foam, meaning there is no air or empty space besides the holes in the foam.
So, this means that we are solving for the volume of a cone and then multiplying it by 150 to find out how much foam is required for 150 cones.
V = πr^2(h/3)
π = 3.14
r = 1.5
h = 12
Now, we can plug in our values to solve for volume.
V = 3.14(1.5^2)12/3
V = 3.14(1.5^2)4
V = 3.14 x 2.25
V = 7.065
Round it to the nearest hundredths.
7.065 --> 7.07
Lastly, multiply by 150.
7.07 x 150 = 1,060cm^3 of foam
Thus, 1,060cm^3 of foam is required to make 150 cones.

Answer:
x = 32
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin 30 = 16/ x
Multiply each side by x
x sin 30 = 16/x * x
x sin 30 = 16
Divide each side by sin 30
x = 16/ sin 30
x = 16 / (1/2)
x = 32
Answer:
c, x = 32
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin 30 = 16/ x
Multiply each side by x
x sin 30 = 16/x * x
x sin 30 = 16
Divide each side by sin 30
x = 16/ sin 30
x = 16 / (1/2)
x = 32

What is Maya’s biking speed?
PLZ HELP IN A BIG RUSH PLZ PLZ PLZ
Answer:
Maya's biking speed is 8 miles per hour.
Step-by-step explanation:
She can run 18 miles in 3 hours. That means she could run 6 miles in one hour. So, if she can ride her bike 18 miles in 2 hours she can bike 9 miles per hour.
If she bikes for 27 (3 hours) miles and runs 9 miles (1.5 hours) then taking the total of miles dividing it by the time you would get Maya's speed.

F. A reflection over the x-axis and a horizontal stretch
G. A reflection over the y-axis and a horizontal stretch
H. A reflection over the x-axis and a vertical stretch
J. A reflection over the y-axis and a vertical stretch
Answer:
F. A reflection over the x-axis and a horizontal stretch
Step-by-step explanation:
Using Desmos, a well-known graphing-calculator website, you can input the two equations. You can see that the h(x)= -(x/4)^2 equation does in-fact reflect over the x-axis and is wider than x^2, meaning that it has a horizontal stretch.

Equal, equal, not equal, not equal
Step-by-step explanation:
A) Equal, because they have the same height and base. To find the area of a triangle, you use "(b+h)/2". In this situation, the "b" and the "h" are equal.
B) Equal, as they also have the same height and base. To find the area, you use b*h, and they are equivalent.
C) Not equal. The two lengths given are not equal.
D) Not equal. The two triangle's heights are equal, but their bases are not. If you look at the second triangle, you can see that if is further from the triangles' intersections. This means that the base is larger than the one on the left.

Solve for x:
[tex]x-2(x-\frac{3}{2}x)=2(4-x)+10[/tex]
Answer:
[tex]x = \frac{9}{2}[/tex]
Step-by-step explanation:
x - 2 (x - [tex]\frac{3x}{2}[/tex]) = 2 (4 - x) + 10
x − 2 × [tex]\frac{-x}{2}[/tex] =2(4−x)+10
x−(−x)=2(4−x)+10
x+x=2(4−x)+10
2x=2(4−x)+10
2x=8−2x+10
2x=−2x+18
2x+2x=18
4x=18
[tex]x = \frac{18}{4}[/tex]
[tex]x = \frac{9}{2}[/tex]
