The perimeter is

or
[tex]2 \frac{6}{7} \: units[/tex]
EXPLANATION
The perimeter of a plane figure is the distance around the figure.
The perimeter of a square is given by the formula,
[tex]p = 4l[/tex]
Where
[tex]l = \frac{5}{7} [/tex]
is the length of one side of the square.
We therefore substitute this value into the equation to obtain,
[tex]p = 4 \times \frac{5}{7} [/tex]
This will simplify to
[tex] p = \frac{20}{7} units[/tex]
or
[tex]2 \frac{6}{7} \: units[/tex]

A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t² + 704t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit.
Answers
Putting in vertex form: -16(t^2 -44t +484) + 704
h(t) = -16(t-22)^2 + 704
It takes 22 seconds to reach the maximum height, which is the vertex of the parabola at (22,704)
Answer:
22 secs.
Step-by-step explanation:
h(t) = -16t^2 + 704t
The maximum will happen where the first derivative is equal to 0.
h’(t) = -32t + 704
-32t + 704 = 0 => -32t = -704 After subtracting 704 from both sides of the equation
Now divide both sides of the equation by -32
t = 22 secs.
Double Check: recalculated/reasonable ✅ ✅
Answer: 22 secs.
Just an interesting aside. After 22 secs, the projectile will be -16(22)^2 + 704(22) = -7744 + 15,488 = 7744 units up as its maximum height.

So, the answer is 2 x 2 x 2 x 7 or 2^3 x 7
Final answer:
To express 112 as a product of prime numbers in index form, we perform prime factorization to get 2⁴ x 7.
Explanation:
To express 112 as a product of prime numbers in index form, we start by performing prime factorization, which is breaking down a composite number into the prime numbers that, when multiplied together, give the original number.
Let's find the prime factors of 112:
112 is divisible by 2 (the smallest prime number).112 ÷ 2 = 5656 is also divisible by 2, so 56 ÷ 2 = 28Continuing this process, 28 ÷ 2 = 14, and then 14 ÷ 2 = 7The number 7 is a prime number and cannot be divided further.So, we can express 112 as a product of prime factors as 2⁴ × 7¹ or simply 2⁴ × 7, since any number to the power of 1 is the number itself.
Which graph represents the function y – 3 = (x – 4)?
Answers
The graph represents the function y = (x - 1), as per linear equation.
What is a linear equation?A linear equation represents an equation that has one or multiple variables with the highest power of the variable is 1.
The given equation is:
y - 3 = x - 4
⇒ y = x - 1
Therefore, for x = 0, y = - 1
for x = 1, y = 0
for x = - 1, y = - 2
Therefore, the graph will pass through points (0, - 1), (1, 0), (- 1, - 2).

James buys a shirt and a pair of socks on sale for 25% off. if the price of the shirt before the sale was $24 and he spent a total of $24, what was the original price of the socks?
Answers
Answer:
The original price of socks was $8.
Step-by-step explanation:
James buys a shirt and a pair of socks on sale for 25% off.
The price of the shirt before the sale was $24 that means after discount the price was:
[tex]24-(0.25\times24)[/tex] = $18
And James paid a total of $24.
That means the price of socks after discount is = [tex]24-18[/tex] = $6
Let the original price of socks be x. And after 25% discount, it was for $6.
So, [tex]x-0.25x=6[/tex]
=> [tex]0.75x=6[/tex]
x = 8.
Hence, the original price of socks was $8.

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?
Answers
her H = r and R = 0.5r so the volume of the cone is
1/3 * pi * (0.5r)^2 * r
= 1/3 * pi * 0.25 r^3
= (1/12) pi r^3 Answer
Answer:
Volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]
Step-by-step explanation:
Formula to find the volume of a cone is V = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here r is the radius of the cone and h is the height of the cone.
Since radius of cone = [tex]\frac{1}{2}(\text{Radius of cylinder})[/tex]
= [tex]\frac{r}{2}[/tex]
Height of the cone = radius of the cylinder = r
Now we put the values of radius and height of cone in the formula
Volume of cone = [tex]\frac{1}{3}\pi (\frac{r}{2})^{2}(r)[/tex]
= [tex]\frac{1}{3}\pi(\frac{r^{2}}{4})(r)[/tex]
= [tex]\frac{1}{12}\pi r^{3}[/tex]
Therefore, volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]

What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?
Answers
Rewrite the given equation in slope intercept form:
5 y = 10 – 2 x
y = - 0.4 x + 2
Since the two lines are parallel, therefore they have similar slope which is – 0.4, so the equation is:
y = - 0.4 x + b
Given that x = 5, y = -4, find for b:
-4 = - 0.4 (5) + b
b = -2
So the answer is:
y = - 0.4 x – 2
or
2 x + 5 y = - 10

Dependent. When the first balloon is taken, it affects the ratio of red to blue balloons.

Whatever color the sister choses is irrelevant, eliminating answers A and B, but it does change the odds. If there are 5 red balloons and 4 blue balloons, if the sister is given a blue balloon, the odds of the brother receiving a red balloon increases (vis versa).
what translation rule can be used to describe the result of the composition of (x,y) --> (x - 9,y - 2) and (x,y) --> (x + 1, y - 2) ? PLEASE HELPPPPP!!!!!
Answers
we know that
the rule of the translation A is
[tex](x,y)-----> (x-9,y-2)[/tex]
that means
the translation is [tex]9[/tex] units to the left and [tex]2[/tex] units down
the rule of the translation B is
[tex](x,y)-----> (x+1,y-2)[/tex]
that means
the translation is [tex]1[/tex] unit to the right and [tex]2[/tex] units down
therefore
the rule of the composition A+B is
[tex](x,y)-----> (x-9+1,y-2-2)[/tex]
[tex](x,y)-----> (x-8,y-4)[/tex]
that means
the translation is [tex]8[/tex] units to the left and [tex]4[/tex] units down
so
the answer is
[tex](x,y)-----> (x-8,y-4)[/tex]
The translation rule that describes the result of the composition of the transformations (x, y) --> (x - 9, y - 2) and (x, y) --> (x + 1, y - 2) is (x, y) --> (x - 8, y - 4). This rule is obtained by sequentially applying each transformation to (x, y).
Explanation:When we talk about compositions of translations in geometry, what we are doing is carrying out one translation after the other. So, if we have two translations: (x, y) --> (x - 9, y - 2) and (x, y) --> (x + 1, y - 2), we perform these operations sequentially.
First, we apply the transformation (x,y) --> (x - 9, y - 2). Then we take these new coordinates and apply the second transformation (x,y) --> (x + 1, y - 2). The result of this composition is (x - 9 + 1, y - 2 - 2) = (x - 8, y - 4), as you add (or subtract) the changes introduced by each translation.
So, the translation rule that can be used to describe the result of the composition of these transformations is: (x, y) --> (x - 8, y - 4).

Katlin divided a fraction by 1/2 the result was a mixed number. was the fraction less than or greater than 1/2? EXPLAIN.
Answers
When you divide by a fraction, it is equal to multiplying by its reciprocal. The reciprocal of 1/2 is 2/1, or just 2. Therefore, dividing by 1/2 equals the same thing as when you multiply by 2.
A mixed number has a whole number and a fraction added together. So, the mixed number must be greater than 1.
1/2 is equal to 0.5, and 0.5 multiplied by 2 equals 1. A fraction less than 1/2 multiplied by 2 would equal a number less than 1, while a fraction greater than 1/2 would equal a number greater than 1.
Because a mixed number must be greater than 1, and a fraction greater than 1/2 multiplied by 2 would be greater than 1, the fraction that resulted in a mixed number after being multiplied by 2 must have been greater than 1/2.
