(i have the answer for part i, i just need hel with ii and iii)
Answers
Answer:
(-1, -5), (-1/2, -3), (-1, -9)Step-by-step explanation:
The function in vertex form is:
f (x) = a(x - h)² + k, where (h, k) is the vertexf(x) = (x - 1)² - 3i) y = f(x) - 2 = (x - 1)² - 3 - 2 = (x - 1)² - 5 ⇒ h = 1, k = -5
Minimum point:
(- 1, -5)ii) y = f(2x) = (2x - 1)² - 3 = 4(x - 1/2)² - 3 ⇒ h = 1/2, k = -3
Minimum point:
(-1/2, -3)iii) y = 3f(x) = 3((x - 1)² - 3) = 3(x - 1)² - 9 ⇒ h = 1, k = -9
Minimum point:
(-1, -9)

A ladder is leaning against a vertical wall. The distance from the top of the ladder to the base of the wall is 17 feet. The distance from the base of the wall to the bottom of the ladder is 7 feet. What is the length of theladder (nearest tenth)?
Answers
Answer:
18.4 feet
Step-by-step explanation:
-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.
-let the ladder be C, the wall be a, the base to the bottom be b.
-substitude into the equation, which will leave us with:
C^2 = 17^2 + 7^2
C^2 = 289 + 49
C^2 = 338
C = square root of 338, which is 18.4 feet!

Select the procedure that can be used to show the converse of the
Pythagorean theorem using side lengths chosen from 2 cm, 3 cm, 4 cm, and
5 cm
Answers
Answer:
The correct option is C
Step-by-step explanation:
I attached an image that forms the complete question.
The converse Pythagorean theorem states that, "If the square of the longest side of a triangle is equal to the square of the other two sides, then the triangle is a right triangle."
That is if c is the longest side of a triangle and then a and b are the other sides, then if,
c² = a² + b², the triangle is a right triangle.
Looking at all the options, option C fits the theorem well. Because
3² + 4² = 5² implies the triangle is a right triangle and the converse theorem is established.
The option D also looks close, but it's not correct because you can just draw any two sides and put the right angle in between them. The longest is always the part of the triangle that is opposite to the right angle, 90°. If for instance, you draw 3 and 5 then put the right angle in between them, 4 will take the position of the longest side which is wrong.
Therefore, the correct option is c.

c

The stock of Company A gained 5% today to $54.60. What was the opening price of
the stock in the beginning of the day?
Answers
Answer: $51.85
Step-by-step explanation:
To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money for 1%. Then you multiply 5 to figure out 5%. Lastly, you would subtract the answer by $54.60 since your finding out how much it was at the beginning of the day. Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85
$51.85

The radius r of the base of a cone is given by the equation r=(3Vπh)1/2, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for π.
The radius is about
a___inch(es).
Answers
Answer:
1 inch.
STEP BY STEP EXPLANATION:
We are given with the following equation r=(3V/πh)^1/2. By the picture we know that "V' is volume which translated to 5 in this problem, "π" is 3.14 and "h" is out height or 4in (in the picture we get all this values).
Therefore everything that there is left is to substitute and answer.
r = (3[5]/3.14[4])^1/2 - multiply the numbers

8
Answers
Answer:
B, -4
Step-by step explanation
Step 1: Simplify both sides of the equation.
3(2x+8)=0
(3)(2x)+(3)(8)=0(Distribute)
6x+24=0
Step 2: Subtract 24 from both sides.
6x+24−24=0−24
6x=−24
Step 3: Divide both sides by 6.
6x/6= -24/6
Answer: x= -4
