The perimeter of a rectangle is 46 inches. If the width of the rectangle is 8 inches, what is the length?
Answer:
The length is 15 inches
Step-by-step explanation:
Using the formula [tex]P=2(l+w)[/tex], you will do this:
[tex]l=\frac{p}{2} - w = \frac{46}{2} - 8 = 15in[/tex]

Identify the following for the exponential function y = 5(1/4)x.
a. Growth or decay?
b. Initial value
c. Growth/decay factor
d. Growth/decay rate (as a percentage)
Answer:
A)
Decay
B)
Initial value is 5.
C)
The decay factor is 0.75.
D)
75%
Step-by-step explanation:
An exponential function is given by:
[tex]f(x)=a(r)^x[/tex]
Where a is the initial value and r is the rate.
We have the function:
[tex]y=5(1/4)^x[/tex]
So, a = 5 and r = 1/4.
A)
Remember the guidelines:
It is exponential growth if r > 1. And it is exponential decay if r < 1. (And r must be positive.)Our rate is 1/4 or 0.25.
It is less than 1, so our function is exponential decay.
B)
The initial value is the value in front of our rate.
So, our initial value in this case is 5.
C)
The decay factor will be 1 - r, where r is our rate.
Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.
So, we are decaying by a factor of 0.75.
D)
To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.
So, 0.75 will be 75.0 % or smply 75%.
It is a 75% decay.

Answer:
14x+3
Step-by-step explanation:
The given expression is as follows :
4x + 3(2x +1) + 4x
We need to find the equivalent expression for the above.
So,
4x + 6x +3 + 4x
Adding x terms,
14x+3
Hence, the correct equivalent expression is 14x+3.

Four times Audrey’s age plus 7 is Parag’s age. Parag is 51. What is
Audrey’s age?
Answer:
I think 5.
Step-by-step explanation:
You'd do this backwards.
51 ÷ 4 = 12.75
12.75 - 7 = 5.75.
You could either round that to 6 or keep it at 5.
Answer:
I believe it is 5 or 6. the answer I got was 5.75 so I am leaning towards 6 but I would let someone else answer.
Step-by-step explanation:
ok so we have 51 so then you would divide by 4 and subtract 7.
Find the distance, c, between (–4, –3) and (2, 1) on the coordinate plane. Round to the nearest tenth if necessary.
Answer:
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-(-4))²+(1-(-3))²)
d=√(6²+4²)
d=√36+16
d=√52
d=7.21110255...
d=7.2
Step-by-step explanation:

The distance between the points on the coordinate plane is 7.2 units.
What is coordinate geometry?Coordinate geometry is the study of geometry using the coordinate points. It provides a link between geometry and algebra through line graphs and curves.
For the given situation,
The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)
The formula for the distance between points,
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
On substituting the above points,
⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]
⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]
⇒ [tex]d=\sqrt{52}[/tex]
⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]
Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

Answer:
-9.32*10^- is -9.32*10^-5
What is m∠1?................
Answer:
144
Step-by-step explanation:
to find the missing angle in side of the triangle we subtract 111 and 33 from 180
180-111-33=36
so the angle inside of the triangle equals 36 to find the one on the outside of the triangle we subtract 36 from 180
180-36 which equals 144 so 1=144

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

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].

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.

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.
