By taking the product between the mass and the acceleration, we will see that the force is:
F = 640 N
What is the force of the long jumper?
By the second Newton's law, we know that a force can cause motion on a body by accelerating it, such that the force is equal to the product between the mass of the object and the acceleration.
F = m*a
F = forcem = massa = acceleration.Here we know that:
m = 80kg
a = 8 m/s^2
Replacing that we get:
F = (80 kg)*( 8 m/s^2) = 640 N
Where N is the unit Newton.
1 N = 1 kg*m/s^2

- Lyra was trying to determine the slope ratio for the triangle at right, and she
says the answer is 2.675. Isiah claims that cannot be correct. Who is
right? How do you know?
Answer:
Isiah is correct. The slope is about 0.344.
Step-by-step explanation:
Lyra and Isiah want the slope of the hypotenuse in a triangle with an angle of elevation of 19°.
SlopeThe slope is the ratio of "rise" to "run". In a right triangle, that is the ratio "opposite"/"adjacent". This ratio is the tangent of the angle of elevation.
tan(19°) ≈ 0.344
The slope is about 0.344. Isiah is correct.
Isiah knows Lyra is not correct because the slope in a triangle with a 45° angle is 1. Lyra' value of 2.675 is about right for an angle of 69.5°, much greater than either 45° or the given angle of 19°.
__
Additional comment
Unfortunately, the diagram is not drawn to scale. This is often the case with diagrams in geometry problems. The diagram here is misleading in that it seems to show a slope greater than 1 for a 19° angle.

What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The quadratic equation is,
⇒ 8x² + 16x + 3 = 0
Now,
Solve the equation as;
⇒ 8x² + 16x + 3 = 0
⇒ 8x² + 16x = - 3
⇒ 8 (x² + 2x) = - 3
Now, Using completing the square as;
⇒ 8 (x² + 2x + 1) = - 3 + 8
⇒ 8 (x + 1)² = 5
⇒ (x + 1)² = 5 / 8
⇒ (x + 1) = ±√5 / 8
⇒ x = ±√5/8 - 1
⇒ x = - 1 ± √5/8

Refer to the figure below. M
The measure of the angle ∠C is 17°.
The angle having a measure equal to 32° and the angle ∠B form a linear pair. They are supplementary angles. When two lines cross, they generate a pair of neighbouring angles called a linear pair. A linear pair's two angles are always supplementary, which means their measurements add up to 180 degrees. The sum must be equal to 180°.
32° + ∠B = 180°
∠B = 180° - 32° = 148°
Now, we will use the angle sum property of a triangle. The sum of all the angles in a triangle is equal to 180°.
∠B + ∠C + 15° = 180°
148° + ∠C + 15° = 180°
∠C + 163° = 180°
∠C = 180° - 163° = 17°

a rectangular storage area is to be constructed along a side of a building. a security fence is required along the remaining three sides of the area. what is the maximum area that can be enclosed with 703 ft of fencing?
The largest area that may be surrounded by fencing is 61776.13 m².
A building's side will have a rectangular storage room built into it. The remaining three corners of the space need security fencing.
The maximum area is enclosed within 703ft of fencing.
Let x = width
L = length
The perimeter with 3 sides;
L + 2x = 703
L = (703 - 2x)
Let, Area = x * L
Now, replace L with (703 - 2x);
A = x * (703 - 2x)
A = 703x - 2x²
To get the max area by finding the axis of symmetry;
x = -b/2a
In this equation a = -2; b = 703
x = -703 / (2*-2)
x = 175.75m, ( width for the max area )
To get the max area, x=175.75;
A = -2(175.75²) + 703(175.75)
A = -61776.12 + 123552.25
A = 61776.13 m² is a max area
Hence, The maximum area that can be enclosed with 703ft of fencing is 61776.13 m².

Which one of the following is NOT equivalent to 3/4? 16/24 15/20 6/8 24/32 PWEASE HURRY THESE ARE ALL MY POINTS

16/24 = 2/3
15/20 = 3/4
6/8 = 2/3
24/32 = 3/4
Answer: 16/24 and 24/32 are not equivalent to 3/4
Step-by-step explanation:
Equivalent fractions represent the same value, even though they look different.
Here, when we convert every fraction to its simplest form, we can verify if they are equal.
(16/24) ÷ (8/8) = 2/3
(15/20) ÷ (5/5) = 3/4
(6/8) ÷ (2/2) = 3/4
(24/32) ÷ (4/4) = 6/7

1.92% is the probability .
Describe probability using an example?
By dividing the number of preferable possibilities by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained. The most basic illustration is a coin toss. There are only two outcomes that can occur when you flip a coin: either heads or tails.The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
so
P = x/y
Find out the probability that the first student selected will be left-handed
we have
x = 6
y = 40
substitute
P = 6/40
Simplify
P = 3/20
the probability that the second student selected will be left-handed
we have
x = 6 - 1 = 4
y = 40 -1 = 39
substitute
P = 5/39
the probability that the 2 students selected will both be left-handed
Multiply the probabilities
P = 3/20(5/39) = 15/780
Convert to percentage
Multiply by 100
