Answer:
(3, 0 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 5x² - 30x + 45 ← is in standard form
with a = 5, b = - 30 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{-30}{10}[/tex] = 3
Substitute x = 3 into the function for corresponding value of y
y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0
vertex = (3, 0 )
Answer:
Vertex is (3,0)
Step-by-step explanation:
Given y= 5x^2 - 30x + 45
y = 5 ( x^2 - 6x + 9)
= 5 ( x -3 )^ 2 + 0
Standard formula of parabola is y = a(x - k)^2 + k where vertex is (h,k)
Here, h = 3 and k = 0
So, Vertex is ( 3, 0)

An elephant at an animal sanctuary weighs 5.5 tons. He receives a daily nutritional supplement. The instructions say to give 1 fluid ounce of supplement for every 250 pounds of body weight. How many fluid ounces of supplement should the elephant receive? no options I need to type it in.
Answer:
44 fluid ounces.
Step-by-step explanation:
It's important to keep in mind that 1 ton is 2,000 pounds.
5 x 2,000 = 10,000 pounds.
You have to add 1,000 pounds because of the '.5' at the end of the 5. That leaves you with 11,000 pounds.
Now, you have to divide by 250 to find how many fluid ounces you need.
[tex]\frac{11,000}{250}[/tex] = 44.
You need 44 fluid ounces of supplement.
Answer:
44

Answer:
The distance between the two points is 10.3
Step-by-step explanation:
To find the length of the line joining the two points, we are going to use the distance formula
Mathematically, we have this as;
D = √(y2-y1)^2 + (x2-x1)^2
From the question;
(x1,y1) = (-3,4)
(x2,y2) = (2,-5)
Thus, we have it that;
D = √((-5-4)^2 + ((2-(-3)^2
D = √81 + 25
D = √(106)
D = 10.3

We know a or b != 0
but a-b==0 so both are the same unknown number
b/a must = 1
so
a/b is equivalent to b/a as a/b=1 as well.

Elaine has a $25 gift card. She uses the card each
month to purchase a magazine for $3.50 at the
bookstore. How much money will Elaine have
remaining on her gift card after 7 months?
Answer:
$0.50
Step-by-step explanation:
multiply 3.50 by 7 and you get 24.5. $25.00-$24.50= $0.50
Answer:
0.5
Step-by-step explanation:
Well lets start with a basic equation.
$25=3.50(7)
25= 24.5 multiply 3.50 and 7
25-24.5=0.5 subtract the total from the whole
After using the card for 7 months she will have 5 cents left on her card.
Pepe compró una caja de chocolates en $5.950, incluido el 19% de IVA. ¿Cuál es el precio de la caja de chocolates sin el IVA?
Answer:
$4819.5
Step-by-step explanation:
Pepe bought a box of chocolates for $ 5,950, including 19% VAT. What is the price of the box of chocolates without VAT?
The price of chocolates = $5,950
VAT = 19%
We need to find the price of the box of chocolates without VAT.
VAT is applied on the Cost price of the object.
Price = $5,950 - 19% of $5,950
[tex]=5950- 5950\times \dfrac{19}{100}\\\\=\$4819.5[/tex]
So, the price of the box without VAT is equal to $4819.5.

The function D(t) defines a traveler's distance from home, in miles, as a function of time, in hours.
Question:
The function D(t) defines a traveler’s distance from home, in miles, as a function of time, in hours.
[tex]D(t) = \left \{ {{300t + 125,\ 0 \le t < 2.5} \atop {880,\ 2.5 \le t \le 3.5}} \right.[/tex]
[tex]75t + 612.5,\ 3.5 < t \le 6[/tex]
Which times and distances are represented by the function?
(a)The starting distance, at 0 hours, is 300 miles.
(b) At 2 hours, the traveler is 725 miles from home.
(c) At 2.5 hours, the traveler is 875 miles from home.
(d) At 3 hours, the distance is constant, at 880 miles.
(e) The total distance from home after 6 hours is 1,062.5 miles.
Answer:
At 2 hours, the traveler is 725 miles from home. At 3 hours, the distance is constant, at 880 miles. The total distance from home after 6 hours is 1,062.5 miles.Step-by-step explanation:
Given
[tex]D(t) = \left \{ {{300t + 125,\ 0 \le t < 2.5} \atop {880,\ 2.5 \le t \le 3.5}} \right.[/tex]
[tex]75t + 612.5,\ 3.5 < t \le 6[/tex]
Required
Select the right options
(a) t = 0 hours, d(t) = 300 miles.
To check this, we make use of:
[tex]D(t) = 300t + 125, 0 \le t < 2.5[/tex]
So, we have:
[tex]D(0) = 300*0 + 125[/tex]
[tex]D(0) = 0+125[/tex]
[tex]D(0) = 125[/tex]
(a) is incorrect
(b) t =2 hours, d(t) = 725 miles
To check this, we make use of:
[tex]D(t) = 300t + 125, 0 \le t < 2.5[/tex]
[tex]D(2) = 300 *2 + 125[/tex]
[tex]D(2) = 600 + 125[/tex]
[tex]D(2) = 725[/tex]
(b) is correct
(c) t = 2.5 hours, d(t) = 875 miles
To check this, we make use of:
[tex]D(t) = 800, 2.5 \le t \le 3.5[/tex]
So, we have:
[tex]D(2.5) = 800[/tex]
(c) is incorrect
(d) t = 3 hours, d(t) = 880 miles constant
To check this, we make use of:
[tex]D(t) = 800, 2.5 \le t \le 3.5[/tex]
So, we have:
[tex]D(3) = 800[/tex]
(d) is correct
(e) t = 6 hours d = 1,062.5 miles.
To check this, we make use of:
[tex]D(t) =75t + 612.5,\ 3.5 < t \le 6[/tex]
So, we have:
[tex]D(6) =75*6 + 612.5[/tex]
[tex]D(6) =450 + 612.5[/tex]
[tex]D(6) =1062.5[/tex]
(e) is correct
less than equal to or greater than 3827
Answer:
it is less than, greater than, equal to, and less than
Step-by-step explanation:
if the numerator is greater than the denominator the fraction is greater than 1 and therefore you will have a number greater than 3827, if the numerator is less than the denominator the fraction is less than 1 and you will have a number less than 1, if the numerator and denominator are equal the fraction is equal to 1
Answer:
2. 3,827 > 8/3 3. 3,827 > 8/8 4. 3,827 > 3/5
Step-by-step explanation:
In problem 2. 8/3 as a decimal is 2.6 so that means 3,827 is greater. In problem 3. 8/8 as decimal is 1 so that means 3,827 is greater. In problem 4. 3/5 as a decimal is 0.6 so that means 3,827 is greater. i hope this helps have a good day :)
