What scale factor did Dionne use? 1/2 , 2/3 , 3/2 , 2
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Calculate the scale factor, using the ratio of corresponding sides, image to original.
Using the vertical line image = 4 and original = 6 , then
scale factor = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

A quadratic equation has x = -2 + 3i as a solution and passes through the point (-1, -15). Write the quadratic equation in standard form.
Answer:
The standard form of the quadratic equation is f(x) = 2/3·(x + 2)² + 6
Step-by-step explanation:
The given solution of the quadratic equation is x = -2 + 3·i
A point on the path of the quadratic equation = (-1, -15)
The general form of the quadratic equation is f(x) = a·x² + b·x + c
When f(x) = 0, (At which the solution is found), we have x = -2 + 3·i
Substituting gives;
0 = a·(-2 + 3·i)² + b·(-2 + 3·i) + c
0 = 4·a - 12·a·i - 9·a - 2·b + 3·b·i + c
0 = 3·i·(b - 4·a) - 5·a - 2·b + c
∴ b = 4·a
c = 13·a
The general equation becomes
f(x) = a·x² + 4·a·x + 13·a
Also, when x = -1, f(x) = -15
f(-1) = -15 = a·(-1)² + 4·a·(-1) + 13·(-1)
-15 = a - 4·a - 13 = -3·a - 13
-3·a = -15 + 13 = -2
a = 2/3
The general form of the quadratic equation is therefore;
f(x) = 2/3·x² + 8/3·x + 13·2/3 = 2/3·x² + 8/3·x + 26/3
f(x) = 2/3·x² + 8/3·x + 26/3
The minimum value occurs at d(f(x)/dx = 0 = d(2/3·x² + 8/3·x + 13·2/3)/dx = 4/3·x + 8/3 = 0
x = -8/3 × 3/4 = -2
Therefore;
The minimum value of the quadratic function is f(-2) = 2/3·(-2)² + 8/3·(-2) + 13·2/3 = 6
The coordinates of the minimum point, which is the vertex point (h, k) = (-2, 6)
The standard form of the quadratic equation f(x) = a(x - h)² + k, is therefore;
f(x) = 2/3(x - (-2))² + 6 = 2/3·(x + 2)² + 6
f(x) = 2/3·(x + 2)² + 6
Also (h, k) can be gotten from h = -b/2a = -8/3/(2 × 2/3) = -2
k = c - b²/(4·a) = 26/3 - (8/3)²/(4 × 2/3) = 26/3 - 8/3 = 18/3 = 6
k = 6
The standard form of the quadratic equation f(x) = a(x - h)² + k becomes;
f(x) = 2/3·(x + 2)² + 6
The depth of water near a boat dock is collected by a buoy. The data shows that the water level reached 11 feet during high tide at 2:00am and a level of 8 feet during low tide at 9:00am. The depth can be modeled by a sinusoidal function. How deep will the water be at noon? Round your answer to the nearest hundredth. HINT: The equation that models this is y=1.5sin (25.72(x+1.5))+9.5
uh is the problem y=1.5sin?

Step-by-step explanation:
Sam is baking cakes at her parents' bakery. She gets paid $20 a week in addition to $4 for every cake she bakes. She made $60 this week. Write an equation to show how many cakes Sam baked this week.
60 + 4x = 20
20 − 4x = 60
60 − 4x = −20
20 + 4x = 60
Answer:
20+4x=60

Michelle wants to start a babysitting club and decides to call a meeting. As a thank you to everyone for coming she decides to order pizza. She orders two large pepperoni and two extra-large cheese pizzas and the total comes to $30.00. When the delivery person arrives she hands him a $50.00 bill. How much change should she get back? If she tipped the delivery person 10% how much would she get back?
Answer:
I am not sure if my math is correct but I got $15 dollars in change.
Step-by-step explanation:
$50 times 0.10 (10%) equals $5. $50.00 minus $30.00 is $20.00. $20 minus $5 is $15.

Have a marvelous day!! {:0)
Answer:
4 1/4 or 4 3/12
Step-by-step explanation:
Multiply the denominator by 5
3 x 5 = 15
Add 15 + 2
17/3
Now multiply 17/3 by 3/4
17 x 3 = 51
3 x 4 = 12
So it is 51/12
Simplify
17/4
Convert to mixed fraction
4 1/4
Even though this isn't an answer choice, it is the most simplified version of the answer.
The answer you would choose, however, has to be 4 3/12
Hope this helped :)
