Emma poured 40 fl oz. of grape juice equally into 5 cups. How much grape juice does each cup contain?
fl oz. per cup ?
Answers
Answer:
The correct answer is 8 fluid ounces per cup.
Step-by-step explanation:
To solve this problem, we need to divide the total amount of grape juice that Emma has (40 fl oz) by the number of cups she is pouring the juice into (5).
40 oz total/5 cups = 8 oz/cup
Therefore, each cup contains 8 fl oz.

Answers
Answer:
A. 86.64%
B. 80
C. y(t)= 80[tex]e^{0.8664t}[/tex]
D. y(5.5) = 9388
E. y(t) = 8134 bacteria for every hour
F. 8.28 hours
Step-by-step explanation:
a. The bacteria count after 4 hours y(4) = 2560
The bacteria count after 12 hours y(12) = 2621440
equation 1: ye^4k = 2560
equation 2: ye^12k= 2621440
divide (2) by (1),
e^8k = 1024
Taking ln both sides:
ln(e8k ) = ln(1024)
8k = 6.931
k=0.8664 // after dividing both sides by 8
rate of growth k% = 0.8664*100 = 86.64%
b. substituting for k in equation 2:
ye^4*0.8664 = 2560
Initial bacteria count y(4) = 80
c. y(t)= 80e^0.8664t
d. the number of bacteria after 5.5 hours => y(5.5) = 80[tex]e^{0.8664(5.5)}[/tex] ≈ 9388
e. y'(5.5) = 80*0.8664e^0.8664(5.5) = 69.31e^0.8664(5.5) = 8134
f. for bacteria population = 104000
where ye^0.8664t = 104000
y = 80
80e^0.8664t = 104000 //divide both sides by 80
e^0.8664t = 1300
ln(e^0.8664t = ln(1300)
t = 7.17 / 0.8664 = 8.28 hours

Vertex:
I need this answered ASAP please !
Answers
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )

Option B
Step-by-step explanation:
Domain of a function is represented by the set input values or x-values
Range of the function is represented by the set of output values or y-values.
From the graph attached,
y-values are varying from y = - 9 to y = 8.
Therefore, range of the function from the given graph will be,
-9 ≤ y ≤ 8
Option B will be the correct option.

A serving dish has a parabolic surface with the vertex (0, 0) at the center of the dish. When the width of the dish is 6 inches, the depth of the dish is 3 inches. The equation that models the shape of the serving dish is y = ax2. What is the value of a?

Answers
Answer:
B
Step-by-step explanation:
1/3
The required value of a is 1/3 for parabola [tex]y = 1/3x^2[/tex].
A parabolic dish with vertex (0,0) at the center, width is 6 inches and depth is 3 inches. y = ax² where a is to be determined.
A parabola is a cross-section cut out of the cone and represented by an equation [tex]y=4ax^2[/tex].
Here,
Vertex is at the center of the parabolic plate (0,0),
with the help of the width and depth coordinate of the one corner is(3,3).
Now put these coordinates in y = ax²
3 = a3²
a = 3/3²
a = 1/3
Thus, The required value of a is 1/3 for the parabola [tex]y = 1/3x^2[/tex].

Answer:
343π/6 cm³ ≈ 179.6 cm³
Step-by-step explanation:
The formula for the volume of a sphere is one of the volume formulas worth memorizing. It is ...
V = (4/3)πr³
For r = 3.5 cm, the volume is ...
V = (4/3)π(3.5 cm)³ = 343π/6 cm³ ≈ 179.6 cm³
The volume of air in the balloon is about 179.6 cm³.

The equation [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1}}[/tex], the points are (-5, -3) and (2, 4), so to know which is which just do it by order, so in this case [tex]y_{1} = 4, y_{2} = -3, x_{1} = -5, x_{2} = 2[/tex] basically like i said, just in order.
So let's separate the equations into 2 for now:
[tex]y_{2} - y_{1}[/tex] = 4 - (-3) = 4 + 3 = 7
[tex]x_{2} - x_{1}[/tex] = 2 - (-5) = 2 + 5 = 7
So put it together into the fraction and it's 7/7 which is 1, so the slope is 1
