Alex jogged round a 400-m track. He took a total of 16 min to jog 3 rounds of
the same track.
(a)
(b)
Find the total distance that Alex had jogged.
Find Alex's average speed in m/min.
19
Answer: [tex]1200 m[/tex]
[tex]75\ m/min[/tex]
Step-by-step explanation:
Given
Alex Jogged 3 rounds of 400 m track
It took 16 min to Jog 3 rounds
(a) Total distance Alex had Jogged
[tex]\Rightarrow 3\times 400=1200\ m[/tex]
(b) Average speed is the total distance by the total time
[tex]\Rightarrow \dfrac{1200}{16}=75\ m/min[/tex]
Given sec A = 5/3 and that angle A is in Quadrant I, find the exact value of csc A in simplest radical form using a rational denominator.
9514 1404 393
Answer:
5/4
Step-by-step explanation:
The relationship between the sec and csc functions is ...
csc(A) = sec(A)/√(sec²(A) -1)
For the given value of sec(A), this is ...
csc(A) = (5/3)/√((5/3)² -1) = (5/3)/√(16/9) = (5/3)/(4/3)
csc(A) = 5/4

At time t = 0 years, a forest preserve has a population of 1500
deer. If the rate of growth of the population is modeled by
R(t) = 2000e0.231 deer per year, what is the population at time
t=3.
The population of deer at time t=3 years is approximately 4128 deer.
What is an exponential function?An exponential function is a mathematical function of the form [tex]f(x) = a^x[/tex], where a is a positive constant called the base, and x is the input variable. The exponent x represents the power to which the base a is raised.
The rate of growth of the deer population is given by the function [tex]R(t) = 2000e^{(0.231t)}[/tex], where t is the time in years since t=0.
To find the population at time t=3, we need to evaluate R(3) using the given function:
[tex]R(3) = 2000e^{(0.231\times 3)[/tex]
[tex]R(3) = 2000e^{0.693}[/tex]
R(3) ≈ 4127.72
Therefore, the population of deer at time t=3 years is approximately 4128 deer.

Find the acceleration. I don’t understand this, please help
Answer:
At t = 9, Whitney's acceleration will be -0.2 miles per minute.
Step-by-step explanation:
Remember that the acceleration is the derivative of velocity.
Since we want to find Whitney's acceleration at t = 9 and we are given the velocity function, we can simply find the derivative of the point at t = 9. In other words, a(9) = v'(9).
For the interval (7, 11), we simply have a line. So Whitney's acceleration at t = 9 will be equivalent to the slope of that line.
We have the two points (7, 0.8) and (11, 0). So, the slope between them is:
[tex]\displaystyle m=\frac{0-0.8}{11-7}=\frac{-0.8}{4}=-\frac{1}{5}[/tex]
So, a(t) = v'(t) = -0.2 ∀t ∈ {t | 7 < t < 11}. Then at t = 9, Whitney's acceleration will be -0.2 miles per minute.

A TV has a listed price of $751.98 before tax. If the sales tax rate is 8.75%, find the total cost of the TV with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$817.78
Step-by-step explanation:
To find the tax you must do the equation:
751.98 x 0.0875
(Btw, 0.0875 is decimal form of 8.75%. Always turn the percentage into a decimal before finding the tax or sale amount)
751.98 x 0.0875 = 65.80.
Now, add the sale tax amount and the original price:
751.98 + 65.80 = 817.78
Therefore, the answer is 817.78.

Two variables are said to interact when ____. a. the two variables are differentially affected by a third variable b. both variables produce a change in the subjects' scores c. both variables are equally influenced by a third factor d. the effect of one independent variable depends on the levels of the second variable
Answer:
a.) the effect of one independent variable depends on the levels of the second variable
Step-by-step explanation:
In regression, an interaction effect comes to play whenever the effect that an independent variable has on a dependent variable changes, as regards to value(s) of other independent variables( one or more variables). The variables that give interaction effect as a result of interaction with each other is reffered to as "interacting variables" For instance, in a research whereby how "Male gender versus female gender" and their " dieting B and dieting D" influence their " weight loss" There would be interaction effect in a situation where by a " female gender" that operate on " diet B" shed more weight compare with " male gender" that operate on " diet B". It should be noted that two variables are said to interact when the effect of one independent variable depends on the levels of the second variable

Shopping for school supplies, you recently spent $22 to purchase a notebook, a box of pencils, and a package of pens. The box of pencils costs $2 less than the notebook. The package of pens costs 3 times as much as the box of pencils. Choose a variable. Define the variable. Write and solve an algebraic equation to find the cost of each item you purchased. Please show work for Notebook and Box of Pencils and Package of pens. And an equation. (I WILL GIVE POINTS AND BRAINLY PLEASE HELPPPPPPP)
Answer:
Cost of the box of pencils = x = $4
Cost of the notebook = x+2 = 4+2 = $6
Cost of package of pens = 3x = 3(4) = $12
Step-by-step explanation:
Let the cost of the box of pencils = x
Cost of the notebook = 2 more than the pencils cost = x+2
Cost of package of pens = 3 times the pencils cost = 3x
The total was $22, so we can say:
(x)+(x+2)+(3x) = 22
5x=22-2
x=20/5
x=$4
Cost of the box of pencils = x = $4
Cost of the notebook = x+2 = 4+2 = $6
Cost of package of pens = 3x = 3(4) = $12

The product of two rational numbers
Answer:
The product of two rational numbers is rational.
So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form since integers are closed under multiplication. Thus, multiplying two rational numbers produces another rational number.
At the local art exhibit, childrens tickets cost $3 each and adult tickets cost $4 each. On a certain day, the exhibit sold 56 tickets and earned $203 in revenue. How many childrens tickets and how many adult tickets were sold?
Answer:
Children=21 Adult=35
Step-by-step explanation:
[using c for children tickets and a for adult tickets]
56=c+a and 203=3c+4a [starting system of equations]
a=56-c ---> 203=3c+4(56-c) [plugging the first eq. into the second]
203=3c+224-4c [simplify]
-21=-c [simplify 2.0]
c=21 [simplify 3.0]
56=21+a [plugging back into org. eq.]
so a=35

What is the value of y in the solution set of the system of linear equations shown below?
y= -x + 12
4x - 2y = 36
A- 10
B- 8
C- 6
D- 2
Answer:
D-2
Step-by-step explanation:
You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2
