Step-by-step explanation:
y=3(4)²+1
=48+1
=49
Answer:
The output is 49
Step-by-step explanation:
If the input is 4, then x = 4.
Replace x with 4 and you have the equation:
3(4)^2 + 1 = 49
Because Y is the output, and Y = 49, the output is 49
What is the value (x)?
Answer:
x = 7
Step-by-step explanation:
You want to subtract 11 from 18 so you get the x alone.
18-11=7
So if you plug it back into the equation it would be
x = 7
write an equation in slope-intercept form for the line that passes through (-3,1) and is parallel to the line described by y=4x+3
Answer:
y = 4x + 13
Step-by-step explanation:
m = 4 at point (-3,1)
y = 4x + b
1 = 4(-3) + b
1 = - 12 + b
b= 13
y = 4x + 13

3x + 8 = 29
3x/3x + 8 = 29/3x
3x + 8 - 8 = 29 - 8
3x/3 + 8 = 29/3
3x /3= 21/3
Answer:
Subtract 8 from both sides
Step-by-step explanation:
3x + 8 - 8 = 29 - 8
3x/3x+8=29/3x^3x+8-8=29-83x/3+8=29/33x/3=21/3
We move all terms to the left:
3x/3x+8-(29/3x^3x+8-8)=0

The wheels on Darlene's car have on 11-inch radius. If the wheels are rotating at a rate of 378 rpm, find the linear speed in miles per hour in which she is traveling.
Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed ([tex]v[/tex]), measured in inches per second, is defined by following expression:
[tex]v = R\cdot \omega[/tex] (1)
Where:
[tex]R[/tex] - Radius of the wheel, measured in inches.
[tex]\omega[/tex] - Angular speed, measured in radians per second.
If we know that [tex]R = 11\,in[/tex] and [tex]\omega \approx 39.584\,\frac{rad}{s}[/tex], then the linear speed, measured in miles per hour, in which Darlene is traveling is:
[tex]v = 11\,in\times \frac{1\,mi}{63360\,in} \times 39.584\,\frac{rad}{s}\times \frac{3600\,s}{h}[/tex]
[tex]v \approx 24.74\,\frac{mi}{h}[/tex]
The linear speed in which Darlene is traveling is 24.74 miles per hour.

Josephine wrote the numbers 1-100 and placed them in a bag. If she selects a number without looking, what is the probability that the number is greater than 78? Input your answer as a decimal or fraction.
Answer:
0.22
Step-by-step explanation:
The numbers that would be greater than 78 would include numbers after 78. that is 79, 80 ... 100
The total numbers greater than 78 is 22.
And there are 100 numbers in the bag . the probability of picking a number greater than 78 is 22/100 = 0.22

Step-by-step explanation:
Slope is equal to the change in y over the change in x , or rise over run.
m = change in y /change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = y 2 − y 1/ x 2 − x 1
Substitute in the values of x and y into the equation to find the slope.
m = 8 − ( 0 ) /3 − ( 1 )
Simplify.
Simplify the numerator.
m = 8 /3 − ( 1 )
Simplify the denominator.
Multiply − 1 by 1
m = 8 /3 − 1
Subtract 1 from 3
m = 8/2

a pair of listening posts picks up a sound, with one listening post recording the sound after the other. the equation x^2 /1890625 - y^2 / 7,109,375=1 represents possible locations of the sound source with units in feet. how far apart are the listening posts?
1,375 feet
2,750 feet
3,000 feet
6,000 feet
Answer:
I'm not sure, but it might be A
Step-by-step explanation:
Vertex is 1375. The other person said it was B, but someone else said it can't be that. The foci is (7356471.694,0) (-7356471.694,0), so can't be that. Guessing, don't take my word for it unless this gets a high rating
The possible location of the sound source with 1375 feet apart. Then the correct option is A.
What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
A pair of listening posts picks up a sound, with one listening post recording the sound after the other.
The equation will be
[tex]\rm \dfrac{x^2}{1890625 }- \dfrac{y^2 }{ 7,109,375}=1[/tex]
The equation represents possible locations of the sound source with units in feet.
The equation can be written as
[tex]\rm \dfrac{x^2}{1375^2}- \dfrac{y^2 }{ 2666.34^2}=1[/tex]
The listening posts are 1375 feet apart.

If you randomly select a letter from the phrase "Terrace Park Wolves rule," what is the probability that you select a consonant? (Your answer must be in the form of a reduced fraction.)
The probability of selecting a consonant is 0.619
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
The phrase is = "Terrace Park Wolves rule"
The number of letters in the phrase = 21 letters
The number of consonants in the phrase = 13 letters
Now ,
The probability of choosing a consonant from the given set of letters =
number of letters in the phrase / number of consonants in the phrase
Probability of choosing a consonant from the given set of letters = 13 / 21
Probability of choosing a consonant from the given set of letters = 0.619
