Answers
Answer:
*3rd option*
y intercept (0, 2)
x intercept (-1/2 , 0)
Step-by-step explanation:
First, rearrange the equation so y is on one side, the rest of the terms on the other.
y+2 = 4x + 4
y = 4x+2
The y intercept is 2 because x=0, y = 2
rearrange where x is on one side
4x = -y + 2
x = -1/4y - 1/2
The x intercept is -1/2 because when y=0, x=-1/2

Johan's water bottle holds 4.2L of water. Johan has drank 51% of water in the bottle. How much, in litres, has he drunk?
Answers
Answer : 2.142L
Step-by-step explanation:
51/100 × 4.2
=51/100 × 42/10
= 2142/1000
= 2.142L
Answer:
2.142 LStep-by-step explanation:
Total Volume = 4.2L = 4200 ml
Amount Drunk = 51%
How much did Johan drink = 51% of 4200 ml
[tex] \frac{51}{100} \times 4200 \\ = \frac{51 \times 42}{1} \\ = 2142[/tex]
2142 ml = 2.142 L
A 93 L batch of Ropivacaine is being made. The specific gravity is 1.01 g/mL. 196.42 g of Ropivacaine and 799.8g of sodium chloride are added. What is the weight of the water to be added to QS the solution?
Answers
Answer:
92.93378 kg
Step-by-step explanation:
Given that:
Volume of Batch = 93 L
= 93 × 1000 (since 1 L = 1000 mL)
= 93000 mL
Specific gravity = [tex]\dfrac{density \ of \ solution}{density \ of \ water}[/tex]
where;
density of water = 1 g/ml
specific gravity = 1.01 g/mL
Density of solution = (1.01 × 1) g/mL
Density of solution = 1.01 g/mL
[tex]Density \ of \ solution = \dfrac{mass \ of \ batch }{volume \ of \ batch}[/tex]
mass of batch = 1..01 g/mL × 93000 mL
mass of batch = 93930 g
Now, the mass of additional water = mass of (batch - Ropivaciance - sodium chloride)
= 93930 g - 196.42 g - 799.8 g
= 92933.78 g
Since 1kg = 1000 g
The weight of the water to be added to the QS solution is:
[tex]=\dfrac{92933.78}{1000}[/tex]
= 92.93378 kg

A bungee jumper dives from a bridge over a river. The function ℎ(푡) = −16푡 % +5푡 +250 gives the approximate height h in feet of the jumper until he hits the water for the first time. The variable t is measured in seconds.
Answers
Answer and Explanation:
Given the function:
ℎ(t)= −16t+5t+250
Where the variable t is measured in seconds. We can plug in t=20 seconds in the function to measure the height in feet of the bungee jumper after 20 seconds.
h(t)= -16×20+5×20+250
h(t)= -320+100+250
h(t)=350-320
h(t)= 30feet
height in feet of the bungee jumper after 20 seconds = 30 feet

A polynominal function that describes an enclosure is v(x)=1500x_x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Answers
Answer:
The answer is below
Step-by-step explanation:
A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Solution:
The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:
V'(x) = 0
V(x) = x(1500 - x) = length * breadth.
This means the enclosure has a length of x and a width of 1500 - x
Given that:
v(x)=1500x-x². Hence:
V'(x) = 1500 -2x
V'(x) = 0
1500 -2x = 0
2x = 1500
x = 1500 / 2
x = 750 feet
The maximum area = 1500(750) - 750² = 562500
The maximum area = 562500 feet²
Answer:
562500 feet²

A local charity receives 13of a fundraiser during a craft fair and a bake sale. The total amount given to charity was $137.45. How much did the bake sale raise?
Answers
Complete question :
A local Charity receives 1/3 of funds raised during a craft fair and bake sale. The total amount given to the charity was $137.45. How much did the bake sale raise
Answer:
$412.35
Step-by-step explanation:
Given that:
Fraction Given to charity from bake sale = 1/3 of amount raised
Amount given to charity = $137.45
Let amount raised from bake sale = x
Hence,
1/3 of x = 137.45
x / 3 = 137.45
x = 137.45 * 3
x = $412.35
Amount raised from bake sale = $412.35

Identify the domain of the function shown in the graph.
A. -5<x<5
B. 0<x<5
C. x is all real numbers.
D. x > 0
Answers
Answer:
The answer is A choice.
Explanation:
By looking at the graph, we notice that at the left side, the domain/x-value stops at -5 and 5.
Thus, the domain is at the left end side to the right end side.
The domain stops at -5 on the left side and 5 on the right side. Thus the answer is
-5 < x < 5.
The A choice.
Understanding
The domain of a function is basically all the values where x is defined, and by defined, it means it has a y value corresponding to it. In this graph, x is defined from -5 to 5. If you look outside this range of numbers (from -5 to 5 on the x-axis) you will not find any y values for them. We can easily say the solution is A.
Solution:
[A] [tex]-5<x<5[/tex]
Note: From what I see from the picture -5 and 5 are included in the domain, either the question is incorrectly written, or the picture isn't clear enough. If so, the answer should be [tex]-5\leq x\leq 5[/tex].
