A car accelerates uniformly from 36 km/h to 72 km/h in 2 seconds. Calculate :a.The acceleration of the car b.The distance covered by the car in that time.
Answer:
(a) The acceleration of the car is 5 m/s²
(b) The distance covered by the car in that time is 30 m
Step-by-step explanation:
Given;
initial velocity of the car, u = 36 km/h = 10 m/s
final velocity of the car, v = 72 km/h = 20 m/s
time for the motion, t = 2 seconds
(a) .The acceleration of the car;
v = u + at
[tex]a = \frac{v-u}{t} \\\\a = \frac{20-10}{2}\\\\a = 5 \ m/s^2[/tex]
(b) The distance covered by the car in that time
[tex]s = (\frac{v+u}{2} )t\\\\s = (\frac{20+10}{2} )*2\\\\s = 30 \ m[/tex]

A circle with radius of \greenD{2\,\text{cm}}2cmstart color #1fab54, 2, start text, c, m, end text, end color #1fab54 sits inside a \blueD{7\,\text{cm} \times 11\,\text{cm}}7cm×11cmstart color #11accd, 7, start text, c, m, end text, times, 11, start text, c, m, end text, end color #11accd rectangle. What is the area of the shaded region? Round your final answer to the nearest hundredth.
Answer:
64.43 cm^264.44 cm^2 using π = 3.14Step-by-step explanation:
The area of the 7 cm by 11 cm rectangle is ...
A = bh
A = (7 cm)(11 cm) = 77 cm^2
The area of the circle of radius 2 cm is ...
A = πr^2 = π(2 cm)^2 = 4π cm^2
If the shaded area lies between the circle and the rectangle, its area is the difference of these:
shaded area = 77 cm^2 -4π cm^2
Using π = 3.14, this area is ...
(77 -4·3.14) cm^2 = 64.44 cm^2
Using π = 3.141592, this area is ...
(77 -4·3.141592) cm^2 ≈ 64.43 cm^2
The shaded area is 64.43 cm^2, (64.44 if you use π=3.14).
_____
Comment on π
Often, you are required to use a specific valued for π, even if that is inappropriate for the number of significant digits required in the answer. In recognition of that, we have offered both the correct answer (64.43) and the one associated with the value of π you may be expected to use.
Answer:
64.43cm ^2
Step-by-step explanation:
First, calculate the area of the whole figure, including the unshaded area.
The area of a rectangle is the length times the width.
7cm x 11cm = 77c[tex]m^{2}[/tex]
Next, calculate the area of the inner figure.
The area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
[tex]\pi[/tex] x 2cm x 2cm = 4[tex]\pi[/tex] c[tex]m^{2}[/tex]
Finally, subtract the area of the inner circle from the area of the outer rectangle.
77 c[tex]m^{2}[/tex] - 4[tex]\pi[/tex] c[tex]m^{2}[/tex] ≈ 64.43 c[tex]m^{2}[/tex]

The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph, photo above
Part A: Is the graph linear or nonlinear? Explain your answer. (2 points)
Part B: In which segments is the graph increasing, decreasing, and constant? (3 points)
Part C: In your own words, describe the motion of the ant, as shown on the graph (6 points)
Answer:
a. The graph is non-linear. If the graph was linear, it would be one continuous straight line.
b. The graph is increasing from x = 0 to x = 2, constant at x = 2 to x = 3, and decreasing from x = 3 to x = 5. So, [0, 2) is increasing, [2, 3) is constant, and [3, 5] is decreasing.
c. The ant starts to travel 6 cm away from the nest for 2 seconds. Between 2 to 3 seconds, it stays the same distance away. Then, after 3 seconds, it comes back to the base. At 5 seconds, it has returned.
Step-by-step explanation:
Answer:
Part A: it is linear because it is not curving and it consists of straight lines.
Part B: in side A it is increasing because it has a positive slope. In side b it is constant because the slope is 0 since it is straight. Finally, side C is decreasing because the slope is negative.
Part C: during side A the ant is crawling out of the hole in 2 seconds. After that, the ant stops for 2 more seconds as shown in side B. Then, he crawls back into the hole as shown by the decrease in distance due to the slope.

******BRAINLIEST IF ANSWERED****** Which equation can be used to find the measure of angle BAC? * inverse tan(5/12) inverse cos(5/13) inverse sin(12/5) inverse tan(12/13)
Answer:
[tex]cos^{-1}(\frac{5}{13} )[/tex]
Step-by-step explanation:
We can see that x is at ∠A.
To find x:
cosx° = 5/13
x = cos^-1(5/13)
sinx° = 12/13
x = sin^-1(12/13)
tanx° = 12/5
x = tan^-1(12/5)
Out of our answer choices, the only one that fits is the inverse cos(5/13).

Zeros of polynomials (with factoring
We want to find the zeros of this polynomial:
p(x) = 2x3 + 5x2 – 2x – 5
Plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answer:
x = -5/2 x=1 x = -1
Step-by-step explanation:
p(x) = 2x^3 + 5x^2 – 2x – 5
Use factor by grouping
p(x) = 2x^3 + 5x^2 – 2x – 5
Factor x^2 from the first group and -1 from the second group
x^2(2x +5) -1( 2x+5)
Then factor out 2x+5
p(x) = (2x+5) (x^2-1)
Factor x^2 -1 as the difference of squares
p(x) = (2x+5)(x-1)(x+1)
Set to zero to find the x intercepts
0 = (2x+5)(x-1)(x+1)
Using the zero product property
2x+5 =0 x-1 =0 x+1 =0
2x = -5 x=1 x=-1
x = -5/2 x=1 x = -1
Answer:
The zeroes are (-1,0), (1, 0) and (-5/2, 0)
Step-by-step explanation:
We can find the zeroes by factoring:
2x^3 + 5x^2 - 2x - 5 = 0
x^2(2x + 5) - 1(2x + 5) = 0
(x^2 - 1)(2x + 5) = 0
(x - 1)(x + 1)(2x + 5) = 0
So x = -1, 1, -5/2.

AB and AC are tangent. Find AB
Answer:
[tex]AB = \frac{11}{2}[/tex]
Step-by-step explanation:
Given
The above diagram
[tex]AB = 3y + 4[/tex]
[tex]AC = 11y[/tex]
Required
Determine length AB
Tangents drawn from the same point of a circle are equal;
This implies that
[tex]AB = AC[/tex]
Substitute values for AB and AC
[tex]3y + 4 =11y[/tex]
Subtract 3y from both sides
[tex]3y - 3y + 4 = 11y - 3y[/tex]
[tex]4 = 8y[/tex]
Divide both sides by 8
[tex]\frac{4}{8} = \frac{8y}{8}[/tex]
[tex]\frac{4}{8} = y[/tex]
[tex]\frac{1}{2} = y[/tex]
Substitute [tex]\frac{1}{2}[/tex] for y in [tex]AB = 3y + 4[/tex]
[tex]AB = 3 * \frac{1}{2} + 4[/tex]
[tex]AB = \frac{3}{2} + 4[/tex]
[tex]AB = \frac{3 + 8}{2}[/tex]
[tex]AB = \frac{11}{2}[/tex]

A piece of aluminum with a mass of 100.0 g has a temperature of 20.0°C. It absorbs 1100 J of heat energy. What is the final temperature of the metal?
Answer:
31.81°CStep-by-step explanation:
Using the formula for calculating heat energy H = mcΔT
m = mass of the aluminum (in g/kg)
c = specific heat capacity of aluminum
ΔT = change in temperature = T - Ti (in °C)
T is the final temperature
Ti is the initial temperature
Given m = 100.0g, c = 0.931096J/g °C, Ti = 20°C, H = 1100J T = ?
Substituting the given values into the formula;
1100 = 100*0.931096 (T - 20)
1100 = 93.1096T - 1862.192
93.1096 T = 1100+1862.192
93.1096 T = 2962.192
T = 2962.192/93.1096
T = 31.81°C
The final temperature of the metal is 31.81°C
Answer:
31.81c
Step-by-step explanation:
1100 = 100*0.931096 (T - 20)
1100 = 93.1096T - 1862.192
93.1096 T = 1100+1862.192
93.1096 T = 2962.192
T = 2962.192/93.1096
T = 31.81°C

Nadine sold two kinds of tickets to her class play. Student tickets cost $3 each, and adult tickets cost $5.50 each. If Nadine sold a total of 25 tickets for $90, how many student tickets did she sell?
Answer:
19 tickets
Step-by-step explanation:
Nadine sold two kinds of tickets to her class play
The student tickets cost $3
Adult tickets cost $5.50
Nadine sold a total of 25 tickets for $90
We are required to find the number of students tickets that were sold
Let x represent the number of tickets sold to students
Let y represent the number of tickets sold to adults
x + y= 25
x= 25-y..........equation 1
Since the total cost of the ticket is $90
3x + 5.50y=90..........equation 2
Substitute 25-y for x in equation 2
3(25-y) + 5.50y= 90
75-3y+5.50y= 90
75+2.5y= 90
Collect the like terms
2.5y= 90-75
2.5y=15
Divide both sides by 2.5
2.5y/2.5=15/2.5
y= 6
Substitute 6 for y in equation 1
x= 25-y
x= 25-6
x= 19
Hence Nadine sold 19 student tickets

Last year, I had 92 APES students and this year I will have 63 APES students. By what percentage will the population of APES students increase.
Answer:
31.52% increase (decrease)
Step-by-step explanation:
To find the decrease in the percentage of students from the previous year to the current year, you must establish a baseline to be your maximum (100%). For this we'll use the 92 students. From here, we need the current 63 students to establish the current percentage.
Simply:
63/92 == .6848 == 68.48%
So our current percentage of students is 68.48%. We want the decrease of the students compared to the previous percentage so we'll need to do the maximum minus the current to get the change (or the decrease).
100% - 68.48% = 31.52%
Thus, the population increase (decrease) for this year is 31.52%.
Answer:
68.47
Step-by-step explanation:
63/92
