2. Give the coordinate rule for a translation up 10 units.
3. What does a translation of the function up 10 units mean in terms of Jeremy's savings?

Part B (Check the third graph)
1. Graph the translation of the function right 10 units.
2. Give the coordinate rule for translation right 10 units.
3. What does a translation of the function right 10 units mean in terms of Jeremy's savings?

Part C
1. Look at the translations, what characteristic of the graph stayed the same in each translation?

2. Look at the original graph and the graph of the translation right 10 units. What vertical translation of the graph in Part B would put the graph back to its original position? Explain how you determined this.

Answer:

C. 5√3

Step-by-step explanation:

To figure this out, we need to apply the Pythagorean Theorem, a² + b² = c², where c is the "HYPOTENUSE". In this case, c is already found for us [10], so the operation we use whenever the hypotenuse is defined is deduction, or subtraction. Apply the Pythagorean Theorem: a² + 25 = 100; 75 = a². Now, to find a, we need to find two numbers that multiply to 75, where one of them is a PERFECT SQUARE, and in this case, they are 3 and 25. Since the square root of 25 is 5 [in this case, NO NON-NEGATIVE root], that gets moved to the outside of the radical, and 3 [NON-PERFECT SQUARE] stays wrapped under the radical, ending up with 5√3. You understand?

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

========================================

We have the points (-1, -4) and (1, 6). Substitute:

[tex]m=\dfrac{6-(-4)}{1-(-1)}=\dfrac{10}{2}=5[/tex]

[tex]y-(-4)=5(x-(-1))\\\\y+4=5(x+1)[/tex]

Convert it to the standard form [tex]Ax+By=C[/tex]:

[tex]y+4=5(x+1)[/tex]          use the distributive property

[tex]y+4=5x+5[/tex]         subtract 4 from both sides

[tex]y=5x+1[/tex]           subtract 5x from both sides

[tex]-5x+y=1[/tex]        change the signs

[tex]5x-y=-1[/tex]

Before the translation, the coordinates of C are (-1, 2).

If we translate C 3 to the left, it becomes (-1 - 3, 2), or (-4, 2).

If we translate C 9 down, it becomes (-4, 2 - 9), or (-4, -7).

Therefore, the coordinates of C' would be (-4, -7).

Hope this helps! :)

The requried coordinates of the translated point C' are (-4, -7). Option A is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

Here,

The coordinates of point C before translation are (-1, 2). If we move point C 3 units to the left, its new coordinates would be (-1 - 3, 2), or (-4, 2). If we then move point C 9 units down, its new coordinates would be (-4, 2 - 9), or (-4, -7).

Therefore, the coordinates of the translated point C' are (-4, -7).

Answer:

Slope is [tex]\frac{1}{3}[/tex]

Good job on the y-intercept!

[tex]f(x)=\frac{1}{3}x+3[/tex] is function represented here.

Step-by-step explanation:

The slope is [tex]\frac{\text{rise}}{\text{run}}[/tex].

Let's start at the left dot on your screen; we are going to figure out how to get to (0,3) only using up, down,right, left.

So since the slope is [tex]\frac{\text{rise}}{\text{run}}[/tex] and we are starting at the left dot trying to get to right, let's find the rise part first.  How much would you need to rise to get on the same level as that dot on the right? You should say the rise is positive 1 (since you go up 1).

Now that we are on the level, what would you need to run from left to right to get to the right dot.  The run is positive 3 (since we went right 3).

So the slope is  [tex]\frac{\text{rise}}{\text{run}}=\frac{1}{3}[/tex]

You did good on the y-intercept! Good job!

The slope-intercept form a line is y=mx+b where m is the slope and b is the y-intercept.

Answer:

It's A, -16.

Step-by-step explanation:

solve by moving all terms with d to the left hand side

subtract 8d from both sides

d + 1 = - 15

- 15 - 1 = -16

-16 = d

The answer is a -16.

When you only have an equation in one variable to solve you will transpose the variable together and get the outcome on the other side.

When you transpose a variable or a constant on the other side, their function gets changed, so you can add, subtract, multiply or divide on both the sides the effect would not change, but you have to keep in mind about the equality holding true.

9d+1=8d-15

As you have to group the variable then subtract 8d on both sides

d+1=-15

After that, you transpose +1 from LHS to RHS

d = -16

Answer:

[tex]6.180 \cdot 10^{-5}[/tex]

Step-by-step explanation:

So I'm going to separate the fraction like so:

[tex]\frac{3.3 \cdot 10^2}{5.34 \cdot 10^6}=\frac{3.3}{5.34} \cdot \frac{10^2}{10^6}[/tex]

I'm going to do the 3.3 divided by 5.34 in my calculator.

3.3/5.34 is equal to 0.6179775 (approximately).

I'm going to use law of exponents to simplify: [tex]\frac{10^2}{10^6}[/tex].

When you are dividing by the same based number, you subtract the exponents. So you will keep the same based number and your exponent will be top exponent minus bottom exponent. Like this:

[tex]\frac{10^2}{10^6}=10^{2-6}=10^{-4}[/tex].

So this is what we have right now before moving on.

The answer is approximately [tex]0.6179775 \cdot 10^{-4}[/tex].

In order for this to be in scientific notation we need the first number to be between 1 and 10 (not including 10). To do this, we move the decimal either left or right depending where it is and change the factor of 10.

So 0.6179775 only needs to have the decimal moved over once to the right so 0.6179775 is [tex]6.179775 \cdot 10^{-1}[/tex]

The exponent of -1 came form us moving it right once.

So now this is what we have so far:

[tex]6.179775 \cdot 10^{-1} \cdot 10^{-4}[/tex]

I brought down the 10^(-4) form earlier because I was focusing on the the other part to be in scientific notation.

So if you have the same based number when multiplying, you add the exponents like so:

[tex]6.179775 \cdot 10^{-1+-4}[/tex]

[tex]6.179775 \cdot 10^{-5}[/tex]

Now I didn't worry about the 4 significant digits until now.

We want the first 4 digits reading the number from left to right on our first number.

[tex]6.180 \cdot 10^{-5}[/tex]

I rounded because the 5th digit was 5 or more.

Answer:

The standard equation is x²/16 + y²/49 = 1

Step-by-step explanation:

* Lets revise the standard equation of the ellipse

- The standard form of the equation of an ellipse with  

   center (0 , 0) is x²/b² + y²/a² = 1 , where  

* The coordinates of the vertices are (0 , ± a)  

* The coordinates of the foci are (0 , ± c), where c² = a² - b²  

* Now lets solve the problem

∵ The vertices of the ellipse are (0 , -7) , (0 , 7)

∵ The coordinates of the vertices are (0 , - a) , (0 , a)

∴ a = 7 , -7

∵ The coordinates of the foci are (0 , -√33) , (0 , √33)

 ∵ The coordinates of the foci are (0 , - c) , (0 , c)

∴ c = -√33 , √33

∵ c² = a² - b²

∵ a² = (7)² = 49

∵ c² = (√33)² = 33

∴ 33 = 49 - b² ⇒ subtract 49 from both sides

∴ -16 = -b² ⇒ multiply both sides by -1

∴ b² = 16

∵ The standard equation of the ellipse is x²/b² + y²/a² = 1

∴ The standard equation is x²/16 + y²/49 = 1

Coordinates of center =

Step-by-step explanation:

Points to remember

Equation of a circle passing through the point (x1, y1) and radius r is given by

(x - x1)² + (y - y1)² = r ²

To find the radius  and coordinates of center

It is given that an equation of circle,

(x - 4)² + (y + 6)² = 52

Compare two equations,

we get  r ²  = 52

r = ±√52

(x - x1)²  = (x - 4)²  then x1 = 4

(y - y1)² = (y + 6)² then  y1 = -6

Coordinates of center = (4, -6)

Answer:

(x − 4)2 + (y + 6)2 = 25

(x − 4)2 + (y − (-6))2 = 52

When I compare my equation with the standard form, (x − h)2 + (y − k)2 = r2, I get h = 4, k = -6, and r = 5. The center is at (4, -6), and the length of the radius is 5.

0 real solutions

Step-by-step explanation:

I guess you are looking for the number of real solutions? Correct me if I'm wrong.

There is something called the discriminant that can help us determine this without actually solving f(x)=0 for x.

The discriminant is the thing inside the square root in the quadratic formula.

It is the thing that reads b^2-4ac.

If b^2-4ac:

A) is negative, then you have 0 real solutions (you could say 2 complex solutions)

B) is positive, then you have 2 real solutions

C) is 0, then you have 1 real solution

So comparing 3x^2+5x+10 to ax^2+bx+c, you should see that a=3, b=5, and c=10.

b^2-4ac

=5^2-4(3)(10)

=25-120

=-95

That is a negative result so you have no real solutions.

The numbers are 10 and 3.

Step-by-step explanation:

STEP 1: Based on the problem, two equations can be set up:

First, "one number is seven less than another." This can be expressed mathematically:

Let x = first number

      y = second number

[tex]x \ - 7 = \ y[/tex]

The second equation is based on "their sum is thirteen."

[tex]x \ + \ y \ = 13[/tex]

STEP 2: Solve for the variables.

In this step, substitute the value of y from Equation 1 into Equation 2:

[tex]x \ + \ (x \ - \ 7) \ = \ 13\\2x \ - \ 7 \ = 13\\[/tex]

Next, solve for x by manipulating the equation:

[tex]2x \ = \ 13 \ + \ 7\\2x \ = \ 20\\\boxed {x \ = \ 10}[/tex]

Now that the value of x is known, it can be used to determine the value of y.

To do this, use the calculated value for x and plug it into Equation 1:

[tex]y \ = \ x \ - 7\\y \ = 10 \ - 7\\\boxed {y = \ 3}[/tex]

Keywords: two equations, two variables

To find the two numbers where one is seven less than the other and their sum is thirteen, a system of equations is set up and solved, revealing that the only possible combination is 10 (larger number) and 3 (smaller number).

To solve the problem where one number is seven less than another and their sum is thirteen, let's set up some equations.

Let x be the larger number and y be the smaller number. We can express the two conditions in the following way:

y = x - 7  (the smaller number is seven less than the larger number)

x + y = 13 (their sum is thirteen)

Substituting the first equation into the second gives us:

x + (x - 7) = 13

Simplifying, we get:

2x - 7 = 13

Adding 7 to both sides, we have:

2x = 20

Dividing both sides by 2, we find:

x = 10

Now we substitute x back into the first equation to find y:

y = 10 - 7

y = 3

So the larger number is 10 and the smaller number is 3. There is only one possible combination of numbers that fit the given conditions.

Step-by-step explanation:

The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.

First we can set up our equation

[tex]cos28=\frac{11}{x}[/tex]

Next we can solve for x by multiplying by x and dividing by [tex]cos 28[/tex]

[tex]x=\frac{11}{cos28}\\\\x=12.458\\\\x=12.5[/tex]

Answer:

c 12.5

Step-by-step explanation:

cos 28 = adjacent side/ hypotenuse

cos 28 = 11/x

Multiply each side by x

x cos 28 = 11/x *x

x cos 28 = 11

Divide each side by cos 28

x cos 28/ cos 28 =11 /cos 28

x = 11 /cos 28

x =12.45827056

To the nearest tenth

x = 12.5
