Answer:
[tex]\frac{-75ft}{30sec}[/tex] or simplified would be [tex]\frac{-2.5ft}{sec}[/tex]
Step-by-step explanation:
In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...
[tex]\frac{-90ft - (-15ft)}{40sec - 10sec} =[/tex] rate of change
[tex]\frac{-75ft}{30sec} =[/tex] rate of change
[tex]\frac{-2.5ft}{sec}[/tex] = rate of change
Therefore, we can see that the rate of change of the diver is [tex]\frac{-75ft}{30sec}[/tex] or simplified would be [tex]\frac{-2.5ft}{sec}[/tex]

Someone help me find the answer please
Answer:
[tex]a^{3}[/tex] * [tex]b^{2}[/tex]
Step-by-step explanation:
[tex]\frac{a^{12} * b^{7} }{a^{9} * b^{5} }[/tex]
Divide the equation (split the equation into parts), to show like terms;
[tex]\frac{a^{12} }{a^{9} }[/tex] * [tex]\frac{b^{7} }{b^{5} }[/tex]
Since dividing two numbers with exponents,( that have the same base), is equivalent to subtracting the exponents and retaining the base, hence:

help!!! I'm not really good at graphs so I also need an explanation please!
Answer:
Hi, I think it's DEGF
Step-by-step explanation:
for y=x－2,
just move y=x down 2 units.
for x=－2,
it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.
for－2x+4,
you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.
for x²-4,
see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.
Hope this will help u!!
An ice cream shop had 316 customers the first weekend it opened. The second weekend it had 468. What is the percent of increase in the number of customers? Round to the nearest percent.
Answer:
48%
Step-by-step explanation:
Given that,
No of 316 customers the first weekend it opened.
The second weekend it had 468.
We need to find the percent of increase in the number of customers.
The formula of percentage is given by :
[tex]\%=\dfrac{|\text{old number-new number}|}{\text{old number}}\times 100[/tex]
Here, old number = 316 and new number = 468
So,
[tex]\%=\dfrac{|316-468|}{316}\times 100\\\\\%=48.10\%[/tex]
or
% = 48%
So, the percent of increase in the no of customers is 48.

to increase an amount by 19% multiple by?
Answer:
1.19
Step-by-step explanation:
The original full amount is 100%.
When you increase the full amount by 19%, you add 19% of the full amount to the full amount, so now you have 119%.
To find 119% of an amount, multiply he amount by 1.19 since 119% = 1.19
Answer: 1.19
What will be the slope of (3,-4) and (1,2)
Answer:
[tex]\boxed {m = 1}[/tex]
Step-by-step explanation:
Use the Slope Formula to determine the slope of two given points:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
First Point: [tex](x_{1}, y_{1})[/tex]
Second Point: [tex](x_{2}, y_{2})[/tex]
-Substitute both points:
First Point: [tex](3, -4)[/tex]
Second Point: [tex](1, 2)[/tex]
[tex]m = \frac{2 + 4}{1 - 3}[/tex]
-Solve for the slope:
[tex]m = \frac{2 + 4}{1 - 3}[/tex]
[tex]m = \frac{-2}{-2}[/tex]
[tex]\boxed {m = 1}[/tex]
Therefore, the slope is [tex]1[/tex].
Solve 3.8 = p/3 - 7.2.
p =
Answer:
The answer is p=33.
Step-by-step explanation:
First you need to add 7.2 to the both sides in order to get rid of 7.2. On the left hand side, you'll have 11.0, directly 11. Since, [tex]\frac{p}{3} =11[/tex] multiply the both sides with 3, and you'll get p=33.

i cant figure out the answer
Answer: 3/10
Step-by-step explanation: times
Answer:
18
Step-by-step explanation:
[tex]\frac{1}{5}[/tex] × 60 = 12 ← number who chose basketball
[tex]\frac{1}{2}[/tex] × 60 = 30 ← number who chose volleyball
That is a total of 12 + 30 = 42 students
Since the remaining students chose soccer, then
60 - 42 = 18 ← number who chose soccer

3/4X - 9 = 27 what does x equal?
Answer:X = 48
Step-by-step explanation:
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
The value of x in the equation given 3x/4 - 9 = 27, is 48.
Given is an equation, 3x/4 - 9 = 27, we need to find the value of x,
To find the value of x, we can solve the given equation step by step. Let's go through the process:
Start with the equation:
3x/4 - 9 = 27
To eliminate the fraction, we can multiply both sides of the equation by 4:
4 × (3x/4 - 9) = 4 × 27
Simplifying, we have:
3x - 36 = 108
Add 36 to both sides of the equation to isolate the variable:
3x - 36 + 36 = 108 + 36
Simplifying further:
3x = 144
Divide both sides of the equation by 3 to solve for x:
(3x) / 3 = 144 / 3
This gives us:
x = 48
Therefore, x equals 48 in the given equation: 3x/4 - 9 = 27.

A. 0
B. 2
C. 4
D. 8
Answer: 0
Step-by-step explanation:
The line runs through the coordinate (0,0), rather than starting at (0,2), (0,4), or (0,8).
Always remember that you read coordinates as (x,y) which..
X is how many spaces right or left
Y is how many spaces up or down.
Answer:
A. 0
Step-by-step explanation:
If you can look at the graph it crosses the y-axis exactly at the origin which is 0. This makes 0 the y-intercept because the line intercepts the y-axis at the point (0,0) making our solution A: 0

A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line. Assuming that field goal attempts can be considered random events, what is the probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line?
Answer:
Step-by-step explanation:
answer should be 0.39
The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is 0.39.
What is the probability?Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
Given:
A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line.
Assuming that field goal attempts can be considered random events.
P = 0.85
n = 5
Standard deviation = √{5 x 0.85 x (1 - 0.85) = 0.79
The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is,
= P (X ≥ 4)
= P (X ≥ 3.5)
= 1 - P(X < 3.5)
= 0.39
Therefore, the probability is 0.39.
