43. A Pop Warner football team had a total loss of 85 yards in penalties on 5 plays. Then triple their yards in penalties on the next 17 plays. What was the final yards the team loss?
Answer:
240 yards lost, if I understand the question correctly.
Step-by-step explanation:
If I read this correctly the team lost 85 yards lost in 8 plays. Then they tripled their loss on the next 17. 3 x 85 = 255 yards lost in the last 17 plays.
Total yards lost was (85 + 255) = 240 yards in 22 plays.

If the bottom row as a result of sythetic division is 1 3 0 4 0, then the quotient is which of the following? Select one:
The quotient of the synthetic division is x^3 + 3x^2 + 4
How to determine the quotient?The bottom row of synthetic division given as:
1 3 0 4 0
The last digit represents the remainder, while the other represents the quotient.
So, we have:
Quotient = 1 3 0 4
Introduce the variables
Quotient = 1x^3 + 3x^2 + 0x + 4
Evaluate
Quotient = x^3 + 3x^2 + 4
Hence, the quotient of the synthetic division is x^3 + 3x^2 + 4

In a right triangle, the length of the hypotenuse is 12 and the measure of one of the angles is 36. What is the length of the other leg
Answer:
Either 9.71 (adjacent to 36°) or 7.05 (opposite 36°)
Step-by-step explanation:
The question doesn't specify which leg is under question. Is it the adacent leg or the opposite leg? I'll assume adjacent.
We can use the acronym
SOHCAHTOA which is a helpful mnemonic for remembering the definitions of the trigonometric functions. For an angle other than the right angle, the following relationships are defined.
SOH: S is sine = Opposite/Hypotenuse
CAH: C is cosine = Adjacent/Hypotenuse
TOA: T is tangent = Opposite/Adjacent
For a side adjacent (A) to the 36° angle, we can use
Cosine = Adjacent/Hypotenuse
Since we know the hypotenuse (12) we can find A:
Cosine(36) = A/12
A = Cosine(36)*12
A = (0.809)*12
Adjacent = 9.71
====================
If the opposite leg is calculated, we would use
Sine= Opposite/Hypotenuse
Sine(36) = Opposite/12
O = (0.5877)*12
Opposite = 7.053

Aster first walks 70m in the direction of 37degree north of east then walks 82m 20 degree south of east ,and finally walks 28m inthe direction of 30 degree west of north ,find displacement and angle from initial point ?
Answer:
Step-by-step explanation:
The displacement is 90.7 meter from initial point.
According to the statement
Aster first walks 70m in the direction of 37 degree north of east
Aster walks 82m 20 degree south of east
Aster finally walks 28m in the direction of 30 degree west of north
We use
β= 37 degree +(30 degree −20 degree) = 47 degree
We can use cosine law to solve for R.
R = ((A)^2 + (B)^2 + 2ABcosβ)^1/2
R = ((70)^2 + (28)^2 + 2*70*28cos47)^1/2
R = (4900 + 784 + 3920*0.682)^1/2
R = (4900 + 784 + 2673.5)^1/2
R = (8357.5)^1/2
R = 90.7 m
So, The displacement is 90.7 meter from initial point.

reach it's maximum height?
20.000 s
8.636 s

The object represented by h(t) = -4.9t² + 40t + 20 would take 4.082 seconds to reach it's maximum height.
What is an equation?An equation is an expression that shows the relationship between two numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.
The height (h) is represented by:
h(t) = -4.9t² + 40t + 20
The maximum height is at h'(t) = 0, hence:
h'(t) = -9,8t + 40
-9.8t + 40 = 0
t = 4.082

Answer: No solutions
Step-by-step explanation: there would be no solutions, because these equations have the same slope and different y-intercepts, so they would end up being parallel from each other, and would never intersect or be equivalent.
Answer:
No solution.
Explanation:
Given equations:
(1) y - 4x = -3
(2) y = 4x + 7
Substitute equation 2 into 1
y - 4x = -3
4x + 7 - 4x = -3
7 = -3
As L.H.S ≠ R.H.S, There are no solution.
The lines are parallel and do not intersect each other. Their slope is same.
If n is a whole number, and 0.01 is between 1/n and 1/n+2, what is the value of n?
The value of n is 99
Integers are the set of numbers including all natural numbers and 0. They are part of the real numbers that do not include fractions, decimals, or negative numbers. Counting numbers are also considered whole numbers.
Natural numbers together with zero (0) are referred to as whole numbers. We know that natural numbers refer to the set of counting numbers starting from 1, 2, 3, 4 and so on. Simply put, integers are a set of numbers without fractions, decimals, or even negative integers. It is a collection of positive integers and zero. Or we can say that integers are the set of non-negative integers.
Integers are the set of natural numbers togethe with the number 0. In mathematics, the set of integers is given as {0, 1, 2, 3, ...}, denoted by the symbol W.
W = {0, 1, 2, 3, 4, …}
All natural numbers are integers.
All integers are real numbers.
It is given that If n a whole number, and 0.01 is between 1/n and 1/n+2, then we need to find the value of n.
1/n+2 < 0.01 < 1/n
1/n+2 < 1/100 < 1/n
n< 100 < n +2
Put n = 99, then we get

The predicted value of the car in the year 2007 is 13310
Given the purchased value of new car in 1998 is $ 32,900
The value of car was $ 19,900 in the year 2003
We need to find the value of the car in the year 2007
Let the predicted value be x
The exponentially constant rate in 2003
32900*x^5 = $19900 (∵ x^5 = 5 years difference that is 1998 to 2003 )
Now In year 2007
2007 = 32900*x^9
x = 0.9043
The predicted value of the car is 0.09043

A building meets the ground at a right angle. the top of a 10-foot ladder is placed against the bottom edge of a window in the building, and the base of the ladder is placed 6 feet from where the building meets the ground.
The bottom edge of the window is 8 inches above the ground, computed using the Pythagoras Theorem.
According to the Pythagoras Theorem, in a right triangle, the square of the hypotenuse, that is, the side opposite to the right angle is equal to the sum of the square of the legs, that is, the two other sides.
If in a right triangle, c is the hypotenuse, and a and b are the two legs, then by the Pythagoras Theorem, we can write:
a² + b² = c².
In the question, we are informed that a building meets the ground at a right angle. The top of a 10-foot ladder is placed against the bottom edge of a window in the building, and the base of the ladder is placed 6 feet from where the building meets the ground.
We are asked to draw a diagram that represents the situation and find the height of the bottom edge of the window from the ground.
We assume the building to be DB, meeting the ground BC at a right angle. At point C, the ladder meets the ground and meets the bottom edge of the window at point A.
The diagram is attached.
Now, we get a right triangle ABC, right-angled at B.
By Pythagoras' Theorem, we know that:
AB² + BC² = AC²,
or, AB² + 6² = 10²,
or, AB² = 10² - 6² sq. inches,
or, AB² = 100 - 36 sq. inches,
or, AB = √64 inches,
or, AB = 8 inches.
Thus, the bottom edge of the window is 8 inches above the ground, computed using the Pythagoras Theorem.
