Felix graphed a system of equations that had no solution. The first equation he graphed was y = {c - 7. PLEASE HELP What was the second equation he graphed?
Answer
A y = 3x + 2
B 3y - I= -21
Cy- 2 = {(x + 1)
Dy - 3x = -7

The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.

This time is determined by the projectile's starting velocity as well as the angle of projection. When the projectile reaches a vertical velocity equal zero magnitudes, it has reached its maximum height. Furthermore, gravity would take over and accelerate the thing downward.

Given that,

y = -2sin[tex](\frac{2\pi (t+1)}{7})[/tex] + 5

For maximum height,

sin(2π(t + 1))/7) = -1

(2π(t + 1))/7) = sin⁻¹ (- 1)

(2π(t + 1))/7) = sin⁻¹ (- 1)

(2π(t + 1))/7) = 3π/2

t + 1 = 21/4

t = 4.25 seconds

Hence,

we can conclude that at t = 4.25 seconds,

The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.

Answer:

Square root2 /3

Step-by-step explanation:

1. Multiply both numerator and denominator by square root of 2.

2. Square root 2 times itself is just 2 that so denominator is 5-2

3. 1 times Square root 2 is just Square root 2. So numerator is Square root 2

4. 5-2=3 so final answer is Square root 2 over 3

Step-by-step explanation:

Answer:

a = 370,000

b = 2,115,000

c = 4,230,000

city c is 11.4 times the population of city a

Step-by-step explanation:

10 to the 5 degree is 100,000. multiply that by 3.7 to get the population of City a.

City C is 2,115,000 * 2.

divide the population of City C by the population of City a.

4,230,000 ÷ 370,000= 11.43

Answer:

x = 20

Step-by-step explanation:

we are given the value of f(x), replace it in the first equation

15 = x - 5

solve for x by adding 5 on both sides

15 + 5 = x

20 = x or x = 20

The value of x is 20.

Given function is,  

                  [tex]f(x)=x-5[/tex]

We have to find the value of x when [tex]f(x)=15[/tex]

Both the race cars will hit the ground at the same time.

The concept used here is free fall formula which can be defined as . Free fall means that an object is falling freely without a forces acting upon it except gravity, a described constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1\/2 gravity x the square of the time falling. Velocity is described as gravity x time.

Here the two cars are free falling in the vertical direction and the initial velocity in the vertical direction is zero. So the landing time of both the cars is only related to the height and the acceleration of gravity.

Hence, the cars are falling from the same height, h and g are the same so they take same time to touch the ground.

Answer:

option D

Step-by-step explanation:

Sum of measure of any 2 sides of a triangle should be greater than the measure of third side.

The triangle will not have the sides 1 foot, 3 feet, and 7 feet, as these sides do not satisfy the triangle inequality theorem so, option D is correct.

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.

Given:

The sides of the triangle are, 1 foot, 3 feet, and 7 feet,

We know that the sum of two sides of a triangle is always greater than the third side,

Calculate the sum of sides as shown below,

1 + 3 = 4

Thus, 1 + 3 < 7.

Therefore, these are not the sides of the triangle.

From triangle BCD:

m∠BCD + m∠CDB + m∠DBC = 180°

67° + 60° + m∠DBC = 180°

m∠DBC = 180° - 127°

An angle ABD is straight angle, so:

m∠ABC + m∠DBC = 180°

m∠ABC +  180° - 127° = 180°
