in explanation
Step-by-step explanation:
as the question told you, if there're 5 counselors, there's a maximum for students of 15. and for 15 counselors, there's a maximum for students of 45. we can easily see that every one counselor can only have 3 students. therefore, you should draw each dot with respect to the counselors' amount, but because two points determine one line, all you need to do is draw (5,15), (15,45) and line them from 0 to 50.

Tell whether (-4, 3) is a solution of the system of linear inequalities.
Answers
Explanation:
Refer to the diagram below. The point (-4,3) marked in red is outside the blue shaded region. So it doesn't make both inequalities true, and therefore not considered a solution.
In contrast, a point like (-5,1) is a solution as it is in the shaded region.
Put another way, the set of all solution points must be below both the solid line and the dashed line. Points can be on the solid line, but must be adjacent to the blue shaded region. The fact (-4,3) is on the solid line doesn't count because its not below the dashed line.
if amount is 7,500, time is 2years and rate is 10% then find principal?
Answers
Answer:
Principal = $9,152.93
Step-by-step explanation:
A = $9,152.93
A = P + I where
P (principal) = $7,500.00
I (interest) = $1,652.93
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 7,500.00(1 + 0.1/12)(12)(2)
A = 7,500.00(1 + 0.008333333)(24)
A = $9,152.93
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $7,500.00 at a rate of 10% per year compounded 12 times per year over 2 years is $9,152.93.

An inground swimming pool contains 2. 3 times 10 Superscript 4 units of water. Which unit of measure was used? teaspoons cubic centimeters fluid ounces gallons.
Answers
The unit of measurement that is used for the water in the swimming pool is 2.3×10⁴ gallons.
What is the Units conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm,
though the real measurement is still the same the units and numerical values have been changed.
As it is given that the volume of the pool or the amount of water that is in the pool is equal to 2.3×10⁴ units.
We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.
Hence, the unit of measurement that is used for the water in the swimming pool is 2.3×10⁴ gallons.

What are trigonometric identities?
Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.
Given that the sides are 3x,4x and 6x. The smallest angle will be calculated as below,
( 3x )² = ( 4x )² + ( 6x )² - 2 (4x) ( 6x)cosθ
9x² = 16x² +36x² - 48x²cosθ
9 = 52 - 48cosθ
cosθ = 43 / 48
θ = cos⁻¹ (43/48)
θ = 26.38°

Step-by-step explanation:
A football is punted from a height of 3.5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function h(t)=- 16t^2 + 45t + 3.5, where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5.5ft on the ball's descent, how long was the football in the air? Round to the nearest hundredth.
*show me how you did it not just the answer please
Answers
The time at which the ball was in the air for the two cases of being dropped and being caught are respectively; t = 0.05 s and t = 2.77 s
What was the time of descent?We are given the function to represent the given height as;
h(t)= -16t² + 45t + 3.5
Since the football is caught at a height of 5.5ft on the ball's descent, then;
-16t² + 45t + 3.5 = 5.5
⇒ -16t² + 45t - 2 = 0
From online quadratic equation solver, we have;
t = 0.05 s and t = 2.77 s
