Sally wants to calculate how fast her little brother can run. What information does she need to know?
Answer: If she's willing to calculate within mph, she needs to know a certain distance her brother can run, and how long it takes to run that distance.
g(x) = 4x – 2
f(x) = x² + 4x
Find g(x) + f(x)
↝ g(x) + f(x) = (4x-2)+(x²+4x)
↝ g(x)+f(x) = 4x-2+x²+4x
↝ g(x)+f(x) = x²+8x-2
Therefore, g(x)+f(x) = x² + 8x - 2

Write the standard form of the line that contains a slope of
1/2 and y- intercept of 3. include your work in your final answer.
Answer:
[tex]x-2y=-6[/tex]
Step-by-step explanation:
The line contains a slope of 1/2 and has a y-intercept of 3.
And we want to write this in standard form.
Let’s first write it in slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
So, substitute 1/2 for m and 3 for b. This yields:
[tex]y=\frac{1}{2}x+3[/tex]
We will convert this to standard form. The standard form is:
[tex]Ax+By=C[/tex]
Where A, B, and C are all integers, and A is positive.
We have the slope-intercept equation:
[tex]y=\frac{1}{2}x+3[/tex]
So, let’s multiply our slope-intercept equation by 2 to remove the fraction. This gives us:
[tex]2y=x+6[/tex]
Now, subtract x from both sides:
[tex]-x+2y=6[/tex]
The coefficient of x should be positive. So, multiply both sides by -1:
[tex]x-2y=-6[/tex]
Hence, our standard form is:
[tex]x-2y=-6[/tex]

Answer:

Step-by-step explanation:
We are given
Mr. Smith's recipe calls for 2 1/2 cups of sugar for the cake and 1 1/4 cups of sugar for the vanilla glaze.
The total amount of sugar he would need
2 1/2 + 1 1/4
= (2 + 1) + (1/2 + 1/4)
= 3 3/4 cups of sugar.
We need this amount of sugar in 1/4 cup scoops.
This is calculated as:
let x be the number of scoops needed
x * 1/4 = 3 3/4
x* 1/4 = 15/4 ( 3 3/4 = 15/4)
x= 15
Therefore, he would be needing 15 , 1/4 cup scoop of sugar

Answer:
f(t) = 17.5cos(π(t-7)/6) +59
Step-by-step explanation:
When modeling earth data that has a daily or annual cyclic variation, the simplest sort of model is a sine or cosine function of some sort. Generally, its period will be 1 day or 1 year (or about 1/2 day, if you're modeling tides).
To write the trig function, you need to know ...
Amplitude (A)Offset (D)Period (here, 1 year) (B)Phase shift (C)These values will go into the general form ...
f(t) = A·cos(2π(t -C)/B) +D
__
In this particular form, the cosine function has a value of 1 when t=C, so we can choose C to be the value of t where f(t) is a maximum. In your data table, the maximum temperature is in July, where you have said t=7. So, C=7.
The period is 12 months, so B=12.
The amplitude (A) is half the difference between the minimum and maximum:
A = (76.5 -41.5)/2 = 17.5
The offset (D) is the average of the maximum and minimum:
D = (76.5 +41.5)/2 = 59
__
Using these values in the above form, we have ...
f(t) = 17.5cos(2π(t-7)/12) +59
__
Additional comments
You can see in the attachment that we have matched the maximum and minimum values exactly. A more sophisticated model is needed to adjust the function to match more of the data points.
Or, you may get a slightly better match if you use a sine regression model (least-squares best fit). That sort of modeling is best done using a graphing calculator or spreadsheet. The details are beyond the scope of this answer.
26) Hailey is 3 times as old as Maverick.
The sum of their ages is 48 years. How
old is Maverick?
Let H = Hailey's age and M = Maverick
Hailey is 3 times as old as Maverick: H = 3M
The sum of their ages is 48 years: H + M = 48
Since H = 3M, substitute 3M in place of H in the second equation:
H + M = 48
3M + M = 48
4M = 48
M = 12
Maverick is 12 years old. Hailey = 3M = 3(12) = 36 years old.

The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle?
40°
70°
100°
140°
The base angle is 70 degrees
How to determine the base angle?For an isosceles triangle, we have:
Vertex angle + 2 * Base angle = 180
This gives
40 + 2 * Base angle = 180
Subtract 40 from both sides
2 * Base angle = 140
Divide both sides by 2
Base angle = 70
Hence, the base angle is 70 degrees

Given the answer for part D, write an expression that will tell you the direction the robot is going if, in the course of its journey, it turns left 21 times and turns right 22 times. Does the order the robot makes the turns in matter for the purpose of knowing the direction it is finally facing?
The answer to part D is in the picture...
Answer:
[(i^21) - (i^22)]d
the direction will not matter because the direction will always be the same no matter what order you choose
Step-by-step explanation:
This is the answer
The expression that will tell you the direction the robot is going will be ((i)²¹*(-i)²²)d i.e. right to the initial direction. And the order does not matter for the direction it is finally facing.
What is rotation in complex plane?When in the complex plane, the line is rotated clockwise, then the line is multiplied by -i and when the line is rotated anti-clockwise, then the line is multiplied by i.
A right turn is the clockwise rotation of the direction vector by the angle of 90°. It is equivalent to multiplying the complex number by -i.
A left turn represents a counterclockwise rotation of the direction vector by the angle of 90°. It is equivalent to multiplying the complex number by i.
Here assume the initial direction vector of the robot is d
the robot is turned to the left 21 times. so now the direction vector will be di²¹. Then it is rotated right 22 times, now the direction vector will be (di²¹)*(-i)²²=d((i)²¹*(-i)²²).
So, now the direction that the robot is going= d((i)²¹*(-i)²²)= di²¹⁺²²=di⁴³= d(-i)= -di
means the robot is the right of the initial direction.
Now the expression that shows the direction that the robot is going is d((i)²¹*(-i)²²).
The order does not matter as the direction will always be the same irrespective of the order.
Therefore The expression that will tell you the direction the robot is going will be ((i)²¹*(-i)²²)d i.e. right to the initial direction. And the order does not matter for the direction it is finally facing.

If x is a positive integer, for how many different values of x is StartRoot StartFraction 48 Over x EndFraction EndRoot a whole number?
Answer:
For 3 different values of x
Step-by-step explanation:
Here, we want to get the values of x for which
√(48/x) is a whole number
We have to consider that the values of x that will make the expression a whole number must be less than or equal to 48
Also, we have to consider that, the division we have to make must yield a perfect square so as to have a whole number square root
The factors of 48 that can yield a whole number are;
1,2,3,4,6,8,12,16,24 and 48
However, the divisions that can yield a perfect square are
3 (yield 16)
12 ( yield 4)
48 ( yield 1)
So the numbers of the value of x that can yield a whole number is 3
