The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car’s average acceleration?
Answer:
[tex]a=4\ m/s^2[/tex]
Step-by-step explanation:
Given that,
The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.
We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,
[tex]a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2[/tex]
So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].

Victoria and Javier are collecting aluminum for a community service project. Victoria previously collected 56 pounds and is collecting at a rate of 8 pounds per hour this weekend. Javier collected 16 pounds earlier and Is now collecting at a rate of 12 pounds per hour. How many hours must pass (x) before the two students have collected the same amount of aluminum (y)?
Answer:
10 hoursStep-by-step explanation:
Victoria collects:
8x + 56Javier collects:
12x + 16They get same amount:
8x + 56 = 12x + 1612x - 8x = 56 - 164x = 40x = 10Help me please I don’t know

-2(x+1)+4x<-10 what’s the solution
Equation/Question:
-2(x+1)+4x<-10 What’s the solution?
Answer/Way I did it:
1. Expand.
-2x-2+4x<-10
2. Simplify -2x-2+4x to 2x-2.
2x-2<-10
3. Add 2 to both sides.
2x<-10+2
4. Simplify -10+2 to −8.
2x<-8
5. Divide both sides by 2.
x<-8/2
6. Simplify 8/2 to 4.
x<−4

Which 3 angles can be constructed together to form a triangle?
90
60°
120°
70
20°
Answer:
90, 70, 20
Step-by-step explanation:
The measure of an angle is 180 so if you add up 90,70,and 20 you get a total of 180
Answer:
70, 20, 90
Step-by-step explanation:
For all triangles, the sum of the angles is 180.
I got these three angles 70, 20, 90.
To double check you can add all the angles together.
70 + 20 = 90, 90 + 90 = 180
Distance and slope for (0,1) & (2,2)
Answer: slope is 1/2 Distance is √ 5 or 2.236
Step-by-step explanation:
slope -
(0,1);(2,2)
(x1,y1)=(0,1)
(x2,y2)=(2,2)
Use the slope formula:
m= y2−y1/ x2−x1
= 2−1 /2−0
= 1 /2

A local charity holds a carnival to raise money. In one activity, participants make a $3 donation for a chance to spin a wheel that has 10 spaces marked with the values 0, 1, 2, 5, and 10. The participant wins the dollar amount marked on the space on which the wheel stops. Let X be the value of a random spin. The distribution of X is given in the table.
A 2-column table with 5 rows. Column 1 is labeled value of a spin with entries
0, .4
1, 0.2
2, 0.2
5, 0.1
10, 0.1
What is the standard deviation of the distribution?

The standard deviation is 2.08.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
We have the data,
X : 0 1 2 5 10
P(X) : 0.4 0.2 0.2 0.1 0.1
CF : 0.4 0.6 0.8 0.9 1
Sum of fx = 2.5
Mean = 2.5
Deviation X = -2.1 -2.3 -2.1 -2 -1.5
X² = 4.41 5.29 4.41 4 2.25
fX² = 1.764 1.058 0.882 0.4 2.225
Now, standard deviation
= √4.329/1
= 2.08

Answer:
ab = 24
so ac is half, so
ac = 12
and the radius is 13,
draw a line from a to o
and its tall will be 13 because it is the radius and o is the center
now use Pythagoras rule
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
put numbers
[tex] {12}^{2} + {b}^{2} = {13}^{2} [/tex]
and solve for b

b. any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1
Step-by-step explanation:
Answer and explanation:
a) This value is equal to one because it is just the number divided by itself.
b) Since any number divided by itself is equal to 1, 6^3/6^3 also has to equal to one. This also means that when we bring the 6^3 up to the numerator, the equation 6^3-3, which simplifies into 6^0 also has to equal 1, because it is equivalent to being divided by itself.

Complete the sentences:
Answer:
a) "impossible event"
b) "certain event"
c) Letter A.
Step-by-step explanation:
a) An event with probability 0 is said to be:
These events are called "impossible events" (but there are more complex cases where we can have probabilities 0, and the events are not necessarily impossible events)
b) An event with probability 1 is said to be
An event with a probability of 1 is an event that will happen, these events are called "certain event"
c) The probability for each outcome of an unbiased experiment of N different outcomes will be 1/N
for example, for a 6-side dice we have 6 outcomes, then the probability of each outcome is 1/6.
For the coin, we have 2 outcomes, then the probability of each outcome is 1/2
Probability of getting a head = 1/2 = 0.5
In the image, we can see that letter A is on the 0.5 value, then the correct answer here is A.
