Write an equation for distance and time of a bug crawling across a number line at -3 m/s that crosses the zero at time zero
Answer:
P = -3t
Step-by-step explanation:
Since it starts at time zero, and our velocity is -3m/s, our equation for position could be modeled for time as P = -3t

PLS HELP ME GIVING OUT BRAINLIEST ANSWER!!
Answer:
4r^2
Step-by-step explanation:
The area of a square is the square of the side length. Since a circle with radius r is inscribed inside the square, the side length of the square is 2r. Therefore, the area of the square is (2r)^2, which is 4r^2.
Note that the area of the circle is [tex]\pi r^2[/tex].

Answer:
34.3
Step-by-step explanation:
Answer: The answer is (34.3)
Step-by-step explanation:
Since you're rounding to the nearest tenth, you gotta look at the hundreds place which is 8. 8 rounds up so therefore, 2 rounds up and becomes 3. Which gives you the answer (34.3)

Show the work for answer, if the area of a pizza is 153.94 square inches, find the length of its diameter
Answer:
14 inch
Step-by-step explanation:
A = πr^2
153.94 = π * r^2
153.94/π = 49.001 = r^2
√49.001 = r = 7
radius * 2 = diameter
7 * 2 = 14 inch diameter
A 15ft. wire is tied to the top of a tree to provide support. If the wire forms a 25° angle with the ground, what is the height of the tree to the nearest hundredth?
Answer: [tex]6.34\ ft[/tex]
Step-by-step explanation:
Given
The length of the wire is [tex]l=15\ ft[/tex]
The Wire makes an angle of [tex]25^{\circ}[/tex] with horizontal
Suppose the height of the tree is h
From the figure, we can write
[tex]\Rightarrow \sin 25^{\circ}=\dfrac{h}{l}\\\\\Rightarrow h=l\sin 25^{\circ}\\\Rightarrow h=15\sin 25^{\circ}\\\Rightarrow h=6.34\ ft[/tex]
Thus, the height of the tree is [tex]6.34\ ft[/tex]
After reviewing the results of a math test, the teacher tells the class that those students who completed their review worksheets scored an average of 10 points higher
on the test than those students who did not complete their review worksheets. Which of the following BEST describes how the teacher likely came to this conclusion?
A. The teacher conducted an observational study by comparing the performance on the test of those who completed their review worksheets to those who did not
complete their review worksheets.
B. The teacher conducted a sample survey by asking students if they completed their review worksheets and if they think they did well on the test.
C. The teacher performed a controlled experiment in which one group of students decided not to complete their review worksheets and the other group decided to
complete their review worksheets.
OD. The teacher performed a random experiment in which the test scores of one group of students would be higher and the test scores of the other group would be lower.
Answer:
A. The teacher conducted an observational study by comparing the performance on the test of those who completed their review worksheets to those who did not complete their review worksheets.
The statement that best describes the method how the teacher likely came to the specified conclusion is: Option A. The teacher conducted an observational study by comparing the performance on the test of those who completed their review worksheets to those who did not complete their review worksheets.
When do we perform observational study, sample survey, controlled experiment, or random experiment?Observational study is usually chosen when the researches the system is likely to produce different result if interfered. Sample survey is done if the population is too big to analyze or destructible as the analysis occurs.Controlled experiment is done manually, specifically to deduce conclusions. Its steps are fixed.Random experiment is done specifically to deduce conclusions, but it is done in a random manner.In the case of testing about test scores, teacher can't use random or controlled experiment as the teacher would more likely work with real data of test scores instead of students faking it.
The sample survey is not needed as getting test scores doesn't destroy them, nor the population of students is too high(assuming math class has small number of students (usually under some hundreds) ).
Observational study is best choice here, and this is done on all students by observing how much students achieved in scored in test and relate it with them completing the review worksheets or not.
Thus, the statement that best describes the method how the teacher likely came to the specified conclusion is: Option A. The teacher conducted an observational study by comparing the performance on the test of those who completed their review worksheets to those who did not complete their review worksheets.

[tex] \frac{ {3x}^{2} - 2x - 1 }{ {x}^{2} } [/tex]
Show a step.
Answer:
[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]
Step-by-step explanation:
we would like to figure out the derivative of the following:
[tex] \displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]
to do so, let,
[tex] \displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]
By simplifying we acquire:
[tex] \displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} } [/tex]
use law of exponent which yields:
[tex] \displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} } [/tex]
take derivative in both sides:
[tex] \displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )[/tex]
use sum derivation rule which yields:
[tex] \rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]
By constant derivation we acquire:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]
use exponent rule of derivation which yields:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )[/tex]
simplify exponent:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )[/tex]
two negatives make positive so,
[tex] \displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3} [/tex]
further simplification if needed:by law of exponent we acquire:
[tex] \displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3} [/tex]
simplify addition:
[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]

4x−3y=18 Step 2 of 2 : Determine the missing coordinate in the ordered pair (?,12) so that it will satisfy the given equation.
Answer:
13.5
Step-by-step explanation:
The point with the missing coordinate is (?, 12), so the value of y is 12. Plug 12 into the equation in the place of y.
4x - 3(12) = 18
4x - 36 = 18
4x = 54
x = 54/4 = 13.5
Answer:39/8
Step-by-step explanation:
4x-3(1/2)=18
4x-3/2=18
4x=18+3/2
4x=39/2
x=39/8

The boat top speed was 2 miles per hour less then 3/5 the cars top speed. The boats top speed was 73 miles per hour.what was the top speed of the car ?
Answer:
Word Problem. Hmm
The Interpretation of the first expression
Let boat top speed be x and car's top speed be y
x= 3y/5 – 2
From the question
x= 73miles per hr
73= 3y/5 - 2
3y/5 = 73+2
3y/5=75
y= 75x5/(3)
y=125miles per hr.
This is the car's top speed. Thanks
