Answer:
y=-3/2x+5
Step-by-step explanation:
3x + 2y = -4
2y=-4-3x /:2
y=-4/2-3x/2
y=-3/2x-2
Slope=-3/2(=m) , because this line is parallel slope is the same, then
y-y1=m(x-x1) ,where
A(4,-1).... x1 =4, y1 =-1
y-(-1)=-3/2(x-4)
y+1=-3/2x+3/2*4
y+1=-3/2x+6
y=-3/2x+6-1
y=-3/2x+5

Answer:
3/4
Step-by-step explanation:
if you convert them all to have the same denominator you find that 3/4 has the biggest numerator.
2/3 = 16/24
1/8 = 3/24
3/4 = 18/24 ← has the greatest numerator so it's the greatest

The volume of a container varies jointly with the square of its radius, r, and its height, h. The
container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic
centimeters. What is the volume of a container with a radius of 4 centimeters and a height of 4
centimeters?
Your answer
Solution:
The volume of a container varies jointly with the square of its radius, r, and its height, h
Therefore,
[tex]v \propto r^2 h\\\\v = k \times r^2h -------- eqn\ 1[/tex]
The container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic centimeters
Substitute v = 377 and h = 10 and r = 6 in eqn 1
[tex]377 = k \times 6^2 \times 10\\\\377 = k \times 360\\\\k = 1.047 \approx 1.05[/tex]
What is the volume of a container with a radius of 4 centimeters and a height of 4 centimeters?
Substitute k = 1.05 and r = 4 and h = 4 in eqn 1
[tex]v = 1.05 \times 4^2 \times 4\\\\v = 1.05 \times 16 \times 4\\\\v = 67.2[/tex]
Thus volume of a container with a radius of 4 centimeters and a height of 4 centimeters is 67.2 cubic centimeter

Second time asking plz help. Linear or exponential. plz help me :(
Answer:
Exponential
Step-by-step explanation:
The change isn't constant for the volume, so it must be exponential.
Using quadratic regression, the equation is:
[tex]y=\frac{19}{63}x^{2}-\frac{968}{105}x+\frac{3312}{35}[/tex]
Answer:
I agree it's exponential, but it's so much simpler than you guys make it out to be. An easy way to check is to measure the distance in the x and y values to see if they change at a constant rate.
for instance; 1) abs(0-3) =3 95-69= 26
2) abs(3-6) = 3 59-50= 19 ...
It's easier, faster, and less to memorize
Paula leaned a 10 ft ladder against a building as shown below. if Paula wants the top of the ladder to reac
h exactly 5 feet up in the building, what is x the distance between the building and the base of the ladder, in feet?
The distance between the building and the base of the ladder is 5√3 feet.
Step-by-step explanation:
Consider a right angle triangle,
Hypotenuse = Paula leaned a 10 ft ladder against a building.Height = the top of the ladder is exactly 5 feet up in the building.Base = 'x' ft, distance between the building and the base of the ladder.From the Pythagorean theorem,
Base, x = [tex]\sqrt{hypotenuse^{2}-height^{2} }[/tex]
⇒ x = [tex]\sqrt{10^{2} -5^{2} }[/tex]
⇒ x = [tex]\sqrt{100-25}[/tex]
⇒ x = [tex]\sqrt{75}[/tex]
⇒ x = 5√3
The distance between the building and the base of the ladder is 5√3 feet.

Eduardo earns a base salary of $30,000 per year and earns $1,875 per car he sells. Which equation can be used to find the number of cars, c, that Eduardo sold in a year he made 46,875 ?
Answer:
The equation is, A =30,000 + 1875n.
He sold 9 cars the year he made that amount of money.
Step-by-step explanation:
Before calculating, let's assign letters to certain variables:-
✓ let "A" be used to represent the total amount earned after adding his base salary to the amount he earned as commission per car he sells.
✓ "P" will be used to represent his base salary (a constant = 30,000)
✓ "n" will represent the number of cars sold within a given year.
✓ "B" will be used to represent his commission per car he sells.
Fixing them into a formula, we have:
A = P + n(B)
Since "P" and "B" are constants of 30000 and 1875 respectively, we substitute the letters for their actual amount in the formula:-
A = 30,000 + n(1875)
A = 30,000 + 1875n +This is now the equation that can be used to calculate the number of cars he sold in the year he earned 46,875).
So, since "A" is now $46,875, we substitute accordingly to find the number of cars he sold in the year he earned such amount.
46,875 = 30,000 + 1875b
1875n = 46,875 - 30,000
1875n = 16875
n = 16875/1875
n = 9 cars
Therefore the equation to be used to determine how many cars he sold when he earned $46,875 is:
A = 30,000 + 1875n
He sold 9 cars the year he earned $46,875.

Answer:
Mode: 33 Mean: 35.5
Step-by-step explanation:
The mode of a data set is the number that appears most often.
So the mode of this set would be 33, since it appears twice.
The mean of a data set is the average of the numbers.
To find the mean (average), add all eight numbers together, then divide by eight...
31 + 29 + 33 + 37 + 43 + 38 + 33 + 40 = 284
284 / 8 = 35.5
So, the mean of the numbers is 35.5!

Brisa's kite is flying above a soccer field at the end of 43 m of string. If the angle of elevation to the kite measures 72degree, and Brisa is holding the kite 1.2 m off the ground. How high above the ground is the kite flying? (Round to the nearest meter)
Answer:
The height the kite is flying above the ground level to the nearest meter is 42m.
Step-by-step explanation:
this is not drown to scale:
|\
| \
x | \ 43m
| \
|___\
Angle is 72º
sine = opposite / hypotenuse
sin 72 = x / 43
0.9510565 = x / 43
therefore x = 40.9m
Brisa is holding the kite 1.2 m off the ground, we also need to add 1.2 m to our calculated height of the kite. Thus, the answer is
40.9 m + 1.2 m = 42.1 m to the nearest meter is 42m.
what is the volume of a sphere with a radius of 5 meters rounded to the nearest square meter.
560m
314m
340m
524m
Step-by-step explanation:
V = 4/3 π r³
V = 4/3 π (5 m)³
V = 524 m³
Final answer:
The volume of a sphere with a radius of 5 meters rounded to the nearest whole number is 524 cubic meters, calculated using the formula V = (4/3)πr³.
Explanation:
The question is asking for the volume of a sphere with a radius of 5 meters. To find the volume of a sphere, we use the formula V = (4/3)πr³, where V is the volume and r is the radius of the sphere. In this case, the radius r is given as 5 meters.
Plugging in the values, we get:
V = (4/3)π(5³) = (4/3)π(125) = 523.6 cubic meters.
When we round to the nearest whole number, we get 524 cubic meters.
Therefore, the correct answer from the options provided is 524m³.

Carson went to pick apples at an orchard.he gave one-third of his apples to his friend Nathan.then he gave one-half of what he had to his friend Nikki.on his way home he dropped one-fourth if what he had left,so that he only had 9 for him and his family.how many apples did Carson pick originally?
Answer:
36 apples
Step-by-step explanation
Step 1 = he dropped 1/4 and was left with 9
Finding 1/3 one third of 9 = 3.
Then 9 +3 = 12
Step 2 He parted with 1/2 and was left with 12
12x2=24
Step 3 He parted with 1/3 and was left with 24
= 12+ 12 + 12 = 36 Where 1/3 of 36 = 24
Answer = 36
Answer:
36
Step-by-step explanation:
Carson had x number of apples to start with.
He gave 1/3 to Nathan. Now Carson has (2/3)x apples left.
He gave 1/2 of what was left to Nikki. Now Carson has (1/2)(2/3)x = (2/6)x = (1/3)x apples.
On the way home, he dropped 1/4, so he has 3/4 of the last amount he had, and the number is 9.
(3/4) * (1/3)x = 9
3/12 x = 9
1/4 x = 9
x = 36
Answer: He picked 36 apples.
Check:
Start with 36 apples.
Give 1/3 to Nathan. Now Carson has 24 apples.
Give 1/2 to Nikki. Now Carson has 12 apples.
Drop 1/4. 1/4 of 12 is 3. 12 - 3 = 9.
Hew only had 9 apples left, so 36 is correct.
A bag contains 9 red marbles,5 green marbles, and 6 purple marbles.
What are the odds of picking a red marble?
The odds or probability of picking a red marble from a bag that contains 9 red marbles, 5 green marbles, and 6 purple marbles is 0.45 or 45%.
Probability refers to the chance, likelihood, or odds that an event occurs out of many possible events.
Probability is a value that ranges from 0 to 1, depending on the level of certainty.
The number of red marbles in the bag = 9
The number of green marbles in the bag = 5
The number of purple marbles in the bag = 6
The total number of marbles in the bag = 20 (9 + 5 + 6)
The probability of choosing or picking a red marble = 9/20 = 0.45 or 45%.
