Correct question is;
Consider these statements written in ordinary language:
A The speed of the car is proportional to the distance it has traveled.
B The car is speeding up.
C The car is slowing down.
D The car always travels the same distance in the same time interval.
E We are driving backwards.
F Our acceleration is decreasing. Denoting by s(t) the distance covered by the car at time t, and letting k denote a constant, match these statements with the following mathematical statements by entering the letters A through F on the appropriate boxes:
s′′<0.
s′ is constant
s′<0
s′′′<0
s′′>0
s′=ks
Answer:
Answers given below.
Step-by-step explanation:
F) acceleration is the second derivative of distance with respect to time.
Thus; s'' < 0
D) Car travels the same distance in the same time interval. This means the speed is constant. Speed is the first derivative of distance with time. Thus;
s' is constant
E) Driving backwards means that speed is; s' < 0
C) Car is slowing down means negative acceleration. Thus; s'' < 0
B) Car is speeding up means acceleration is greater than 0. Thus: s'' > 0
A) Car speed being proportional to the distance it has covered means that; s' ∝ s. Thus;
s' = ks

A model rocket launched directly upward at a speed of 16 meters per second from a helght of 2 meters . The f(t) = - 4.9t ^ 2 + 16t + 2 models the relationship between the height of the rocket and the time after launch, t. In seconds. Which is the maximum height meters the rocket will reach Round to two decimal places Provide your answer below: meters
Answer:
f(t) = 15.06 m
Step-by-step explanation:
The relationship between the height of the rocket and the time after launch, t. In seconds is given by :
[tex]f(t) = - 4.9t ^ 2 + 16t + 2[/tex]
We need to find the maximum height the rocket will reach the ground.
When it reaches the ground,
f(t) = 0
So,
Maximum height,
f'(t) = 0
[tex]-9.8t+16=0\\\\t=\dfrac{16}{9.8}\\\\t=1.63\ s[/tex]
Put t = 1.63 in equation (1).
[tex]f(1.63) = - 4.9\times (1.63 ^ 2) + 16(1.63) + 2\\\\=15.06\ m[/tex]
So, the maximum height of the rocket is 15.06 m.
Samuel says that 25% is greater than 0.3.
Is he correct? Explain your answer.
Answer: No 0.3 as a percentage is larger than 25%
Step-by-step explanation:
'percent' is 'over hundred'
if you convert 0.3 into a percentage it becomes 30 percent
Samuel says that 25% is greater than 0.3 is not correct statement.
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100.
The percentage is denoted by the symbol %.
The percentage is used or most important application is to compare any two quantities. We compare one quantity against another, with the second quantity rebased to 100 by using percentage.
Samuels says that 25% is greater than 0.3 is a false.
25% when it is converted to decimals.
25 divided by 100
we will get 0.25
and if 0.3 is converted to percentage
0.3×100=30%
We know that 30% is greater than 25%.
hence Samuel says that 25% is greater than 0.3 is not correct.

please solve the question. unit 10: circles homework 2: Central angles, arc measures, and arc length.
Answer:
Step-by-step explanation:
(9x-22) + 61 + (5x-7) + 34 = 360
14x = 294
x = 21°
:::::
arc GK = 9x-22 = 167°
:::::
arc HJ = 5x-7 = 98°
:::::
arc HGK = arc GK + 61 + 34 = 262°
:::::
arc GKJ = arc GK + 34 = 201‡
Angles in a circle add up to 360 degrees.
[tex]\mathbf{x = 21}[/tex][tex]\mathbf{GK = 167}[/tex][tex]\mathbf{HJ = 98}[/tex][tex]\mathbf{HGJ = 262}[/tex][tex]\mathbf{GKJ = 201}[/tex]The given parameters are:
[tex]\mathbf{GH = 61}[/tex]
[tex]\mathbf{HJ = 5x - 7}[/tex]
[tex]\mathbf{JK = 34}[/tex]
[tex]\mathbf{KG = 9x - 22}[/tex]
The sum of angles in a circle is 360 degrees.
So, we have:
[tex]\mathbf{GH + HJ + JK + KG=360}[/tex]
So, we have:
[tex]\mathbf{(9x-22) + 61 + (5x-7) + 34 = 360}[/tex]
[tex]\mathbf{14x = 294}[/tex]
Divide both sides by 14
[tex]\mathbf{x = 21}[/tex]
GK is calculated as:
[tex]\mathbf{GK = 9x - 22}[/tex]
[tex]\mathbf{GK = 9 \times 21 - 22}[/tex]
[tex]\mathbf{GK = 167}[/tex]
HJ is calculated as:
[tex]\mathbf{HJ = 5x - 7}[/tex]
[tex]\mathbf{HJ = 5 \times 21 - 7}[/tex]
[tex]\mathbf{HJ = 98}[/tex]
HGJ is calculated as:
[tex]\mathbf{HGJ = HG + GK + KJ}[/tex]
[tex]\mathbf{HGJ = 61 + 167 + 34}[/tex]
[tex]\mathbf{HGJ = 262}[/tex]
GKJ is calculated as:
[tex]\mathbf{GKJ =GK + KJ}[/tex]
[tex]\mathbf{GKJ = 167 + 34}[/tex]

Answer:
1350
Step-by-step explanation:
Answer:
2400 ft²
Step-by-step explanation:
Base = 30x30=900
Next, we have to find the height of the triangles.
15²+20²=c²
225+400=c²
625=c²
c=√625
c=25
Now we can find the surface area of all 4 triangles.
4(1/2)(30)(25)=1500
900+1500= 2400 ft²

Answer:
Step-by-step explanation:
so we need two even intergeters that add to 70 when we multiply the bigger by 2 and add the smaller to that soooo
70= 2*y + x
but we can express x in terms of y b/c it's a consecutive even integer soo
(b/c x+2 = y, then x = y -2)
70= 2*y + (y-2)
70 = 2y + y - 2
72 = 3y
24 = y :) nice the bigger is 24 so the smaller is 22
70 = 2*24 + 22
70 = 48 + 22
70 = 70 nice !
bigger = 24
smaller = 22
:)
Answer:
bigger = 24

Step-by-step explanation:
A researcher compares the effectiveness of two different instructional methods for teaching pharmacology. A sample of 51 students using Method 1 produces a testing average of 81.6. A sample of 76 students using Method 2 produces a testing average of 76.4. Assume the standard deviation is known to be 12.24 for Method 1 and 11.19 for Method 2. Determine the 90% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2. Step 2 of 2 : Construct the 90% confidence interval. Round your answers to one decimal place g.
Answer:
90% confidence interval is: ( 1.7 to 8.7 )
Step-by-step explanation:
Given the data in the question;
Method 1 Method 2
n₁ = 51 n₂ = 76
x"₁ = 81.6 x"₂ = 76.4
σ₁ = 12.24 σ₂ = 11.19
Lets get the Margin of Error(M.E)
M.E = [tex]Z_{\alpha /2[/tex] √(σ₁²/n₁ + σ₂²/n₂ )
for 90% confidence interval
∝ = 1 - 0.90 = 0.10
∝/2 = 0.10/2 = 0.05
[tex]Z_{\alpha /2[/tex] = [tex]Z_{0.05[/tex] = 1.64
so we substitute
M.E = 1.64 × √((12.24)²/51 + (11.19)²/75 )
M.E = 1.64 × √( 2.9376 + 1.669548)
M.E = 1.64 × √( 2.9376 + 1.669548)
M.E = 3.52
so, for 90% confidence interval for x"₁ - x"₂ will be;
C.I = x"₁ - x"₂ ± [tex]Z_{\alpha /2[/tex] √(σ₁²/n₁ + σ₂²/n₂ )
= 81.6 - 76.4 ± M.E
= 81.6 - 76.4 ± 3.52
= 5.2 ± 3.52
Lower Limit = 5.2 - 3.52 = 1.68 ≈ 1.7
Upper Limit = 5.2 + 3.52 = 8.72 ≈ 8.7
Therefore; 90% confidence interval is: ( 1.7 to 8.7 )

Step-by-step explanation:
The sum of a triangle's angles is 180. So, 6x+2x+2x=180. And, 10x=180, and then x=18. Angle C is 2x. To find angle C multiple 18 by 2 to get 36.
Scott is saving coins in a jar. Last week, the jar was 1/4 full. This week, he added more coins, and the jar is now 1/2 full. How much of the jar did Scott fill this week?
Answer:
Scott filled (1/2 - 1/4) of the jar, or 1/4 of the jar this week.
Let me know if this helps!
Answer:
He filled his jar 1/4 more this week.
Step-by-step explanation:
The explanation is very simple, you know that he added 1/4 coins last week and this week he added more coins that filled the jar half way:
1/2 - 1/4 = 1/4
or you can also use:
1/4 + 1/4 = 1/2
