Answer:
The 2nd triangle
Step-by-step explanation:
The second triangle satisfies the equation 4² + 4² = C². Then the correct option is B.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as,
H² = P² + B²
The Pythagoras theorem is applied in the right-angle triangle.
In the second triangle, then the third side of the triangle is calculated as,
4² + 4² = C²
The second triangle satisfies the equation 4² + 4² = C². Then the correct option is B.

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]
You can buy 3 candy bars at quick market for $2.17. How many can you buy for $17.36?

money will be in her account after one year?
Answer: Jenns account has the greater simple interest rate
Step-by-step explanation: The formula for simple interest is:
Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.
For Lindsey:
Solve for r
Lindsey simple interest was 1.2% annually
For Jenn:

Rewriting the equation in the form (x+c)²=d by completing the square
[tex]\left(x+5\right)^2=16[/tex]The solutions to the quadratic equation are:
[tex]x=-1,\:x=-9[/tex]Step-by-step explanation:
Given the equation

I need to know how to write the function with the steps needed to solve.
9514 1404 393
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.
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

The answer is x = 2y - 2Step-by-step explanation:
Question: y = 1/2x + 1
Given:
equation: y = 1/2x + 1
Unknown:
Equation in x = ?
1. Move the x variable to the side that the y is on.
y = 1/2x + 1
-1/2x -1/2x
2. Move the y to the side of the y-intercept
y - 1/2x = 1
-y - y
3. Divide both sides by -1/2 or multiply by -2
-1/2x = -y + 1
*-2 -2(-y + 1)
The answer is x = 2y - 2

Gary's jogging average speed is represented by the equation y=3.5x where y is the distance in miles and x is the time in hours. How far can he go in 84 minutes?
Answer:
Gary can go 4.9 miles in 84 minutes.
Step-by-step explanation:
First, you need to determine the amount of hours 84 minutes represent considering that 60 minutes are equal to an hour:
60 minutes → 1 hour
84 minutes → x
x=(84*1)/60=1.4 hours
Now, 1.4 hours would be the time which is x and you can replace the value on the formula to find y:
y=3.5x
y=3.5(1.4)
y=4.9
According to this, the answer is that Gary can go 4.9 miles in 84 minutes.
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

Three times a number increased by
twice the number is greater than
125. What is the number?
Answer:
x > 25
Step-by-step explanation:
This question relates to algebra. We can solve this problem by creating a variable for the solution (which we will find). We will link the variable in an equation l with the information given.
So let's translate each piece of information mathematically. First, the question tells us "Three times a number." The first part uses multiplication (times) linked to our number (we will use x for our variable). So we write:
3x
The second part is "increased by twice the number" Increasing is adding (+) so we add two times the number. So:
3x + 2x
The final part says "is greater than 125" so we need to use the > sign
3x + 2x > 125
Now we can solve by collecting like terms and moving them to a different side.
5x > 125
x > 25

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.
