Step-by-step explanation:
after how many seconds is needed for a thrown ball to reach a 14-m distance if it's distance is given by the relation d=10+40t-5t? (t=time in seconds)
Answer:
Time, t = 0.1143 seconds.
Step-by-step explanation:
Given that distance, d = 14m
From the equation;
d = 10 + 40t - 5t
d = 10 + 35t
Substituting the value of distance;
14 = 10 + 35t
35t = 14 - 10
35t = 4
t = 4/35
t = 0.1143 seconds.
The time needed for the ball to reach the 14-m distance is 0.1143 seconds.
The thrown ball will reach a 14-m distance after 0.114 seconds.
The relation given is:
d = 10+40t-5t
where, d = 14
In this case, we've to put the value of d into the relation and this will be:
d = 10+40t-5t
14 = 10 + 40t - 5t
Collect like terms
40t - 5t = 14 - 10
35t = 4
Divide both side by 35
35t/35 = 4/35
t = 0.114 seconds.

Step-by-step explanation:
HELLLLPPPPP !!!!!!!! I don't get what we are learning so can someone plz do this and explain it (if you can/want) simplify 3x+15y=45
Answer: x=10
Step-by-step explanation:
Simplifying
3x + 15 = 45
Reorder the terms:
15 + 3x = 45
Solving
15 + 3x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 3x = 45 + -15
Combine like terms: 15 + -15 = 0
0 + 3x = 45 + -15
3x = 45 + -15
Combine like terms: 45 + -15 = 30
3x = 30
Divide each side by '3'.
x = 10
Simplifying
x = 10

On a Ferris wheel, Sarah observes that it takes 45 seconds for her chair to complete a full revolution. Her chair is 30 feet from the axle of the Ferris wheel.
To the nearest hundredth, Sarah’s angular velocity is ____ radians per minute
Answer:
8.38 radians
Step-by-step explanation:
correct on edge 2021
The angular velocity of the Ferris wheel is 8.38 radians/minute.
What is angular velocity?"The angular velocity is the time rate at which an object rotates or revolves about an axis."
It takes 45 seconds for her chair to complete a full revolution.
Therefore, in terms of revolution per minute, the speed is
= 60/45 revolutions/minute
= 4/3 revolutions/minute.
We know, 1 revolutions = 2π radian
Therefore, 4/3 revolutions/minute
= (4/3) × 2π radians/minute
= 8.38 radians/minute
Hence, the angular velocity is 8.38 radians/minute.

A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)^x. To the nearest hundredth, how much sodium-24 can the scientist predict will remain 12 hours after the experiment started?
_mg
Answer:
56.43
Step-by-step explanation:
The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)ˣ.
The amount of the sodium-24 that scientists can predict will remain 12 hours after the experiment started will be given as,
y = 98.8 (0.9544)¹²
y = 98.8 (0.571169)
y = 56.43 mg
The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.

We were just learning these :)
Step-by-step explanation:
So let's start with the whole equation:
10 - 4x + 6 - 2x = -2x
First, combine like terms:
16 - 6x = -2x
Next, add 16 to both sides:
16 + 16 = cancels out and -2x + 16 = 14
6x = -2x
Now, divide 6 on both sides:
6 / 6 = cancels out and -2x / 6 = -.3
x = -.3

What is the slope of this function?
slope = (y2-y1)/(x1-x2)
=(20-8)/(2-1)
=12/1
m = 12
The slope of the given function is 12.
Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
In this case, we are given three points:
Point 1: (x = 1, y = 8)
Point 2: (x = 2, y = 20)
Point 3: (x = 3, y = 32)
The slope of the function is calculated by the formula given as;
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope =(20-8)/(2-1)
=12/1
Slope = 12
The slope is 12.

A. 6
B.-6
C.-4
D. 4
PLEASE EXPLAIN
Your question is incomplete, here is the complete form.
Points J, K and L are collinear with J between L and K. If KJ = 2x - 3, LK = 9x + 7 and LJ = 4x - 8, solve for x:
Answer:
The value of x is -6 ⇒ B
Step-by-step explanation:
∵ J, K, and L are collinear
→ That means they form a straight segment
∵ J is between K and L
→ That means J divides LK into two segments KJ and LJ
∴ LK = KJ + LJ
∵ LK = 9x + 7
∵ KJ = 2x - 3
∵ LJ = 4x - 8
→ Substitute them in the equation above
∴ 9x + 7 = (2x - 3) + (4x - 8)
→ Add the like terms in the right side
∵ 9x + 7 = (2x + 4x) + (-3 - 8)
∴ 9x + 7 = 6x + -11
∴ 9x + 7 = 6x - 11
→ Subtract 7 from both sides
∵ 9x + 7 - 7 = 6x - 11 - 7
∴ 9x = 6x - 18
→ Subtract 6x from both sides
∵ 9x - 6x = 6x - 6x - 18
∴ 3x = -18
→ Divide both sides by 3
∵ [tex]\frac{3x}{3}=\frac{-18}{3}[/tex]
∴ x = -6
∴ The value of x is -6
The value of x for the given problem comes to be -6.
KJ = 2x-3
LJ= 4x-8
LK = 9x+7
What are collinear points?Points that are part of a straight line are called collinear points.
Points J, K, and L are collinear so they will be in a straight line.
So, KJ + LJ = LK
(2x-3) + (4x-8) = (9x +7)
6x - 11 = 9x + 7
-3x = 18
x= -6
Therefore, the value of x for the given problem comes to be -6.
