Answer:
The answer is 5
Step-by-step explanation:
Given g(x)=3x2+3 find x if g(x)=78 = 5
Hope this helped you :)
Answer:
x = ± 5
Step-by-step explanation:
Given
g(x) = 3x² + 3 and g(x) = 78 , then equate the right sides, that is
3x² + 3 = 78 ( subtract 3 from both sides )
3x² = 75 ( divide both sides by 3 )
x² = 25 ( take the square root of both sides )
x = ± [tex]\sqrt{25}[/tex] = ± 5
That is x = - 5 or x = 5
In an effort to prepare for retirement, Zeus decided to sell off some of his powers to Poseidon. Each box of powers contained 4 specific powers. Each box cost Zeus $250. If Zeus wanted to make a profit $900 per box, how much would have to charge Poseidon for each power?
Answer:
$287.50Step-by-step explanation:
From the problem statement the cost price per box is
$250.
And the box contains 4 specific powers, since Zeus plans to make $900 per box which contains 4 powers
we need to find the selling price
profit= selling price-cost price
let the selling price be x
900=x- 250
x=900+250
x= 1150
Selling price = $1150
Hence the unit cost of a specific power in a box that will see a profit of $900 per box is 1150/4= $287.50
Lena is planning on visiting Minneapolis next week on business. Checking her World Time app, she notices that on the day she arrived, the high temperature is forecast to be -12.9 F . What is this temperature in degrees Celsius?
Answer:
-7.11
Step-by-step explanation:

Y-4-4y= -1. Somebody help please
Answer:
Y=-1
Step-by-step explanation:
Y-4-4Y=-1
-3Y=-1+4
-3Y=3
Y=3÷-3
Y=-1
Answer:
y = -1
Step-by-step explanation:
y - 4 - 4y = - 1 Combine like terms
y - 4y - 4 = - 1
-3y - 4 = - 1 Add 4 to each side
-3y - 4 + 4 = -1 + 4
-3y = 3 Divide each side by -3
-3y/-3 = 3/-3
y = -1

Ari received $100 as a birthday gift and has decided to save this
money as well as add $20 of his own money each month. The total
money Ari has saved can be estimated using the equation g(x) =
20x + 100, where x is the number of months and g(x) is the total
amount of money saved.
Answer:
Total amount Ari would have saved after 6 months is $220
Step-by-step explanation:
Ari received $100 as a birthday gift and has decided to save this money as well as add $20 of his own money each month. The total money Ari has saved can be estimated using the equation y = 20x + 100, where x is the number of months and y is the total amount of money saved. How much money will Ari have saved after 6 months?
Solution
Given:
g(x) = 20x + 100
where,
x = number of months
g(x) = the total amount of money saved
How much money will Ari have saved after 6 months?
g(x) = 20x + 100
When x = 6
g(x) = 20(6) + 100
= 120 + 100
= 220
g(x) = $220
Total amount Ari would have saved after 6 months is $220
Zandra went into a candy store to buy jelly beans. She wanted to choose 3 flavors from 12 flavors they sold. How many combinations of 3 flavors could she make
Answer:
220 ways
Step-by-step explanation:
Total number of flavors (n) = 12
Number of flavors to combine (r) = 3
Recall:
nCr = n! ÷(n-r)! r!
nCr = 12! ÷ (12 - 3)!3!
nCr = 12! ÷ 9!3!
nCr = (12 * 11 * 10) / (3 * 2 * 1)
nCr = 1320 / 6
= 220 ways
Alex spends 2/3 of his paycheck p on food and $3 lose change on coffee how much did he spend
Answer:
The total amount Alex spent is $ 9
Step-by-step explanation:
The given parameters are;
The amount Alex spends on food = 2/3 of his paycheck
The amount Alex spends on coffee = $3
Therefore, we have;
Fraction of the paycheck spent on coffee = 1 - 2/3 = 1/3 of p
The amount Alex spends on coffee = 1/3 of his paycheck
Therefore, we have;
1/3 × p = $3
p = 3 × $3 = $9
The total amount Alex spent = $ 9
The amount Alex spends on food = 2/3 × $9 = $6.

Hey there!
72 athletes can eat for 6 days.
1 athlete can eat for 6(72), or 432 days.
54 athletes can eat for 432/54, or 8 days.
They can eat for 2 more days.
Let me know if this helps :)
Answer:
8 days
Step-by-step explanation:
sufficient food for 72 athlete to last 6 days
when 18 athletes are absent : 72-18=54
multiply scouts by days , to see how many food is packed :
72*6=432
then divide the amount of food packed by the number of scout attended:
432/54= 8 days

A pound of fertilizer cover 45 square feet of lawn Vivian bulgakov's lawn measures 8666.7 square feet how much fertilizer to the nearest tenth of a pound does she need to buy
Answer:
193.
Step-by-step explanation:
We would solve this question by cross multiplication.
If a sound of fertilizer covers 45 square feet of lawn and the lawn is 8666.7 square feet
To get fertilizer quantity we have
1 pound = 45 square
Unknown = 8666.7 square feet
8666.7/45
= 192.59 when approximated we get 193.
Therefore she has to buy 193 pounds of fertilizer

Solve for x. 4(2x−3)=11x
Answer: x=-4
Step-by-step explanation:
Answer:
The correct answer is x = -4.
Step-by-step explanation:
To solve this problem, we should first use the distributive property to get rid of the parentheses on the left side of the equation. This is modeled below:
4(2x - 3) = 11x
8x - 12 = 11x
Then, we should subtract 8x from both sides to move all of the variable terms to the right side of the equation.
-12 = 3x
Finally, we can divide both sides by 3 to get the variable x completely alone on the right side of the equation.
-4 = x
Therefore, the answer to your question is x = -4.

X is a normally distributed random variable with mean 95 and standard deviation 3. What is the probability that X is between 89 and 98? Write your answer as a decimal rounded to the nearest thousandth.
Answer: 0.819
Step-by-step explanation:
Given: X is a normally distributed random variable with mean 95 and standard deviation 3.
Then, the probability that X is between 89 and 98 will be:
[tex]P(89<X<95)=P(\dfrac{89-95}{3}<\dfrac{X-mean}{standard\ deviation}<\dfrac{98-95}{3})\\\\=P(-2<Z<1)\ \ \ [Z=\dfrac{X-mean}{standard\ deviation}]\\\\ =P(Z<1)-(1-P(Z<2))\\\\= 0.8413- (1-0.9772)\ \ \ [\text{By p-value table}]\\\\= 0.8185\approx0.819[/tex]
Hence, the required probability = 0.819

Your question has been heard loud and clear.
a)
Initial velocity , U=50km/h = 250/18 m/s
Final velocity , V = 0 (this is because the car finally comes to rest)
From 3rd equation of motion , V^2-U^2=2AS.
Now , for a car that goes 50km/h , it has been proven that miniumum brake distance is 6 metres.
so , S = 6 metres.
Using this , we can find the distance stopped by car , and then we can find time.
0-(250/18)^2=2*A*6
0= 2*A*6+(250/18)^2
0 = -12A + 192.90 ( minus sign because car is deccelerating)
So , A = 16.07 m/s^2
V^2-U^2 = 2AS
0 - 192.90 = 2* 16.07*S
So , S (distance) = 24 metres.
Now , we know time = distance / speed
so , time = 24 / 253 = 0.094 seconds

raise 3 to the 2nd power, then add c to the result
Answer:
Below
Step-by-step explanation:
● 3
● 3^2
● 9
● 9 + c
======================================================
Explanation:
3 to the 2nd power is the same as writing 3^2 in shorthand
3^2 = 3 squared
When we square a number, we're multiplying it by itself (having 2 copies total of the number). Think of a square with side length 3 units. Its area is 3^2 = 3*3 = 9 square units.
From here, we add on c to get our answer 9+c. We don't know the value of c, so we cannot evaluate further. Also, 9 and c are not like terms so we cannot combine them.
Find the value of n.
9 = 9+n
n = 0
Step-by-step explanation:9 = 9 + n
9 - 9 = n
n = 0

Given the points M(-2,-4) and N(1, 5), find the point T that partitions MN in a ratio of 1:2.
Answer:
Point T is (-1,1)
Step-by-step explanation:
Concept:
If there two points (x1,y1) and (x2,y2) which lies on coordinate plane and them it divided by point p in the ratio m:n then coordinate of point p is given by
p (nx1+mx2)/(m+n), (ny1+my2)/(m+n)
__________________________________________
Given
points M(-2,-4) and N(1, 5)
ratio : 1:2
point t is (2*-2+1*1)/(1+2), (2*-4+1*5)/(1+2)
=> (-4+1)/(3), (-8+5)/(3)
=> -3/3 , 3/3
=> -1, -1
Thus, point T is (-1,1)

Answer:
x = -8
Step-by-step explanation:
To answer this equation solve for x. When doing so make sure to get x one side
First subtract 4x from each side. This means the equation is now
x + 6 = -2
Next subtract 6 on both side and you should find x
x = -8
The area of the face of a cube is 9 square centimeters. Use 9 of these cubes to make a rectangular prism. What is the volume of the rectangular prism
Answer:
243 cm^3
Step-by-step explanation:
The faces of a cube are squares.
A = s^2
s^2 = 9 cm^2
s = 3 cm
The side of the square is the edge of the cube and is 3 cm.
V = s^3
V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3
The volume of one cube is 27 cm^3.
The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3
Answer: 243 cm^3
