A motorboat moves across a lake at a constant speed. When it begins, it is 48
km from the shore. After 10 minutes, it is 18 km from the shore. Which
function describes the motorboat's distance from the shore?
O A. y = 10x+48
B. y=-3x + 48
O c. y=-10x + 48
O D. y = 3x + 48
Answer:
b
Step-by-step explanation:
The function describes the motorboat's distance from the shore is y=-3x + 48. So, the correct option is B.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, a motorboat moves across a lake at a constant speed.
Let x be the number of minutes and y be the total distance.
When it begins, it is 48 km from the shore.
Now, (x₁, y₁) =(0, 48)
After 10 minutes, it is 18 km from the shore.
So, (x₂, y₂) =(10, 18)
We know that, Slope(m) =(y₂-y₁)/(x₂-x₁)
= (18-48)/(10-0)
= -30/10
= -3
Substitute, (x, y)=(0, 48) and m=-3 in y=mx+c, we get
48=-3(0)+c
c=48
Substitute, c=48 and m=-3 in y=mx+c, we get
y=-3x+48
Therefore, option B is the correct answer.

bro I'm really stuck with this, and my brain cells are too small to figure this. out, can someone help me? thank you :)
Answer:
B
Step-by-step explanation:
First isolate the variable, x. To do this, use inverse operations. The inverse operation of -4 is +4. So, add 4 on both sides of the equals sign. The positive 4 cancels out the negative 4 on the left side. Add 4 to the other side, -18, for -14. You are left with 7x = -14. Now to get rid of the coefficient, 7. The inverse of x7 is ÷7. So divide 7x by 7 to completely isolate x. On the right side, -14 is divided by 7 to get -2. You are left with x = -2. Wow that was a ted talk :P Anyway, hope this was helpful ^^ lmk if I need to clarify about anything :D Good day man

According to the Triangle Inequality Theorem, if every combination of 2 sides is equal to the third remaining side, then it is a triangle.
3 + 7 > 8
8 + 3 > 7
8 + 7 > 3
Since all of these are true, that means overall, these 3 sides make a triangle.

Question Help The mean finish time for a yearly amateur auto race was 185.64 minutes with a standard deviation of 0.314 minute. The winning car, driven by Sam, finished in 185.29 minutes. The previous year's race had a mean finishing time of 110.3 with a standard deviation of 0.129 minute. The winning car that year, driven by Rita, finished in 110.02 minutes. Find their respective z-scores. Who had the more convincing victory?
Answer:
Sam has the more convincing victory with a greater Zscore value
Step-by-step explanation:
Given that :
Year 1:
Mean finish time (m) = 185.64
Standard deviation (s) = 0.314
Sam's time (x1) = 185.29
Year 2:
Mean finish time (m) = 110.3
Standard deviation (s) = 0.129
Rita's time (x1) = 110.02
Zscore = (x - mean) / standard deviation
Sam's Zscore :
(185.29 - 185.64) / 0.314
= - 0.35 / 0.314
= −1.114649
= - 1.115
Rita's Zscore :
(110.02 - 110.3) / 0.129
= - 0.28 / 0.129
= −2.170542
= - 2.171
Sam has the more convincing victory with a greater Zscore value

Answer:
It should be 125°
Step-by-step explanation:
I just solved for the last interior angle by doing (92+33)-180=55
Then, did 180 - 55 because m1 and the unknown third angle need to add up to 180 because it's a straight line. 180-55=125.

Answer:
Try C and see if it works, but read info below
Step-by-step explanation:
Refer to the equation y=a(x-h)^2+k
If a>0 then the parabola opens up and horizontally compresses (shrinks)
If 0<a<1 then the parabola opens up and horizontally stretches
If a<0 then the parabola opens down and horizontally compresses (shrinks)
h is the horizontal shift (along the x-axis)
k is the vertical shift (along the y-axis)
Given the function f(x)=3(x+1)^2-2, we can identify the values:
a=3, so the parabola opens down and horizontally compresses (shrinks) by a factor of 3
h=-1, so the horizontal shift is one unit to the left
k=-2, so the vertical shift is 2 units down
Given the above information, none of the answer choices are correct unfortunately. Your best option to pick is C.
