Answer:
Initial investment= $777.78
Step-by-step explanation:
Giving the following information:
Last year Hank cashed out his investment account that earned 4.5% simple interest after 10 years of investing. He ended up with $350 in interest on the account.
To calculate the principal (initial investment), we need to use the following formula:
I= P*r*t
I= $350
r= 0.045
t= 10
P= ?
350= P*0.045*10
350/0.45 = P
$777.78= P

Answer:
d = 50t
Step-by-step explanation:
In the table, the values across from each other are equivalent.
[tex]\begin{tabular}{|c|c|}\cline{1-2} Time in hours (t) & Distance in miles (d) \\\cline{1-2} 0 & 0 \\\cline{1-2} 1 & 50 \\\cline{1-2} 2 & 100 \\\cline{1-2} 3 & 150 \\\cline{1-2}\end{tabular}[/tex]
By looking at the second row of the provided table, we can see that d is equal 50 times the value of t. We can write this as an equation:
d = 50t
The correct answer choice is d = 50t, or the 4th option.

First term: 2 3/4 sixth term: 3 7/12 what is the rule
Answer:
we conclude that the rule will be:
[tex]a_n=\frac{31}{12}+\frac{1}{6}n[/tex]
Step-by-step explanation:
Given
[tex]a_6=3\frac{7}{12}=\frac{43}{12}[/tex]
[tex]a_1=2\frac{3}{4}=\frac{11}{4}[/tex]
We know the arithmetic sequence with the common difference is defined as
[tex]a_n=a_1+\left(n-1\right)d[/tex]
where a₁ is the first term and d is a common difference.
so
a₆ = a₁ + (6-1) d
substituting a₆ = 43/12 and a₁ = 11/4 to determine d
[tex]\frac{43}{12}=\:\frac{11}{4}\:+\:5d[/tex]
switch sides
[tex]\frac{11}{4}+5d=\frac{43}{12}[/tex]
subtract 11/4 from both sides
[tex]\frac{11}{4}+5d-\frac{11}{4}=\frac{43}{12}-\frac{11}{4}[/tex]
[tex]5d=\frac{5}{6}[/tex]
Divide both sides by 5
[tex]\frac{5d}{5}=\frac{\frac{5}{6}}{5}[/tex]
[tex]d=\frac{1}{6}[/tex]
as
a₁ = 11/4
[tex]d=\frac{1}{6}[/tex]
Therefore, the nth term of the Arithmetic sequence will be:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting d = 1/6 and a₁ = 11/4
[tex]a_n=\frac{11}{4}+\left(n-1\right)\frac{1}{6}[/tex]
[tex]=\frac{11}{4}+\frac{1}{6}n-\frac{1}{6}[/tex]
[tex]=\frac{31}{12}+\frac{1}{6}n[/tex]
Therefore, we conclude that the rule will be:
[tex]a_n=\frac{31}{12}+\frac{1}{6}n[/tex]

Answer: B. 5
Step-by-step explanation:
Combination
It's a selection of items from a collection, such that the order of selection does not matter.
It can be calculated by using factorials with the formula:
[tex]\displaystyle _mC_n=\frac{m!}{(m-n)!\ n!}[/tex]
Let's calculate:
[tex]\displaystyle _5C_1=\frac{5!}{(5-1)!\ 1!}[/tex]
[tex]\displaystyle _5C_1=\frac{5!}{(4)!\ 1!}[/tex]
Since 5!=5*4! and 1!=1:
[tex]\displaystyle _5C_1=\frac{5*4!}{(4)!\ 1!}[/tex]
Simplifying:
[tex]\displaystyle _5C_1=\frac{5}{1}=5[/tex]

The point (-7, 4) is reflected over the line x= -3. Then, the result point is reflected over the line y = x. Where is the point located after both reflections?
A. (-10, 7)
B. (1, 4)
C. (4, -7)
D. (4, 1)
Answer: D. (4, 1)
Step-by-step explanation:
When we have a reflection over a line, the perpendicular distance to that line is invariant.
Then, if we have the point
(-7, 4) and we have a reflection over the line x = -3
The distance between the x component and the line is:
I -7 - (-3)I = 4
Then the reflected point will also be at a distance of 4 units to the line x = 3, and this is at the point x = 1.
Then the new point is (1, 4)
Now we do a reflection over the line x = y.
This type of reflection just changes the x-component by the y-component, and the y-component by the x-component.
Then the new point will be (4, 1)
Then the correct option is D.
A truck manufacturer selects 3 trucks at random from each of 6 models for safety testing.
What type of sample is this?
The sampling is a an example of random sampling.
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here: A truck manufacturer selects 3 trucks at random from each of 6 models for safety testing.
From each of six models selects 3 models and Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
Thus clearly the sample is random sampling.
Hence, The sampling is a an example of random sampling.

Step-by-step explanation:
Set up a proportion. The ratio number of gray mice corresponds (is across from) the total number of gray mice (24)
5/2 = x/24 Cross multliply
2*x = 5*24 Multiply 5 by 24
2x = 120 Divide by 2
x = 120/2
x = 60 Which represents the number of white mice.
So the white mice + gray mice = 60 + 24 = 84

This question is incomplete, the remaining part of the question is upload as an image alongside this answer.
Answer:
Width = 2x = 2( r/√2 ) = √2 r units
Height = 2y = 2( r/√2 ) = √2 r units
Step-by-step explanation:
From the Figure on the image; lets consider the circle of radius r, centered at the origin.
let ABCD be the largest rectangle that can be inscribed inside the circle.
Let the half width of the rectangle be x, then in right triangle ONB using Pythagorean theorem,
half height of rectangle y = √(r² - x²)
Thus the width of the inscribed rectangle = 2x and height of the inscribed rectangle = 2√(r² - x²)
thus the area of the inscribed rectangle = length × width
⇒ A(x) = 2x(2√(r² - x²))
⇒ A(x) = 4x√(r² - x²)
now in order to maximize the area, we find critical points.
so we find the derivative and set that zero, that is Ai(x) = 0.
so using product rule, we get
A'(x) = 4x × ( -2x / 2√(r² - x²) ) + ( 4 × √(r² - x²) )
A'(x) = ( -4x² / √(r² - x²) ) + ( 4√(r² - x²) )
Now for critical points, set A'(x) = 0
so
( -4x² / √(r² - x²) ) + ( 4√(r² - x²) ) = 0
( 4x² / √(r² - x²) ) = ( 4√(r² - x²) )
x² = r² - x²
2x² = r²
x² = r²/2
x = ±√(r²/2)
Now since x represent the with, it cannot be negative, Thus
x = r/√2
hence
y = √(r² - x²) = √(r² - r²/2) = √(r²/2) = r/√2
Therefore, the dimensions of the rectangle of largest area will be;
Width = 2x = 2( r/√2 ) = √2 r units
Height = 2y = 2( r/√2 ) = √2 r units

Tom and Diane start to race. Tom takes 4 seconds to run 25 yards. Diane runs 20 yards in 3 seconds.
1. who runs faster? Explain how you know.
Answer:
Diane is faster since her speed is higher.
Step-by-step explanation:
We can find each speed in yards per second.
Tom:
25 yards / 4 seconds = 6.25 yards/second
Diane:
20 yards / 3 seconds = 6.67 yards/second
Diane's speed is higher, 6.67 yd/s vs 6.25 yd/s, so Diane is faster.
Answer: Diane is faster since her speed is higher.

Roger has two blue ties, one red tie, two blue coats, and two orange coats. What is the probability that he wears either a blue tie or a blue coat
Answer:
4/7
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given
Total outcome = 2blue ties+1red tie+2blue coats+2orange coats
Total outcome = 7
If he wears a blue tie, then the expected outcome will be 2.
Probability that he wears blue tie = 2/7
If he wears a blue coat, then the expected outcome will be 2.
Probability that he wears blue coat = 2/7.
The probability that he wears either a blue tie or a blue coat will be 2/7+2/7 = 4/7

Answer:

Step-by-step explanation:
The time in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.
t = va
We need to find the expression for d in terms of t and a.
As velocity = distance/time
[tex]t=\dfrac{d}{t}a\\\\t^2=da\\\\d=\dfrac{t^2}{a}[/tex]
So, the distance d is [tex]\dfrac{t^2}{a}[/tex].
