Which of the equations below could be the equation of this parabola?
(0,0)
A. y = 5x2
B. x = -5y2
C. y = -5x2
D. x = 5y2
Answer:
Its B. x = -5y2
Step-by-step explanation:
The equation for the parabola is x = -5y² option (B) x = -5y² is correct.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have a graph of a parabola.
As we can, in the graph of a parabola:
The equation for the left side opening:
x = -ay²
Here a = 5
x = -5y²
Thus, the equation for the parabola is x = -5y² option (B) x = -5y² is correct.

Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix for $2.50 each and y bottles of water for $1.25 each. If Lupe and her friends bought a total of 11 items, how many bags of snack mix and bottles of water did they buy?
bags of snack mix: ?
bottles of water: ?
Answer:
7.5 bags of snack mix, 3.5 bottles of water.
Step-by-step explanation:
This can be found by looking at a system of equations. Setting up our system, we know that they bought 11 items, and that there was a total of $20. Our system would be this:
[tex]x+y=11\\2.5x+1.25y=20[/tex]
We can then solve for a variable in any equation. Let's solve for x in the second equation.
[tex]2.5x+1.25y=20\\2.5x=20-1.25y\\x=8-0.5\\x=7.5[/tex]
Now, we substitute into the other equation.
[tex]x+y=11\\7.5+y=11\\y=11-7.5\\y=3.5[/tex]
We now know both amounts; they bought 7.5 bags of snack mix and 3.5 bottles of water.
A number from 8 to 15 is drawn at random. What is the probability that the number is an even number? O 211 CD A/7 o 5/8 HKD 118 O 1/2
Answer:
4/7
Step-by-step explanation:
numbers between 8 to 15 is 7
so d even numbers are 4
that is d answer is 4/7
The probability that the number is an even number is 1/2.
What is the probability?The probability is defined as the ratio of number of favourable outcomes and the the total number of possible outcome.
A number from 8 to 15 is drawn at random.
The number between 8 to 15 are 8, 9, 10, 11, 12, 13, 14, 15 = 8
Total even number = 8, 10, 12, 14 = 4
The probability that the number is an even number is;
[tex]\rm Probability =\dfrac{Total \ even \ number }{Total \ numbers}\\\\ Probability =\dfrac{4}{8}\\\\ Probability =\dfrac{1}{2}[/tex]
Hence, the probability that the number is an even number is 1/2.

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
From the graph,
We can make two ordered pairs (x, y).
Where y = average energy level and x = the number of hours.
Now,
From the graph, we see that,
The average energy after 1 hour = 7
The average energy after 2 hours = 8
The average energy after 3 hours = 5
The average energy after 4 hours = 5

Given that T=KX/Y,find the percentage increase in T when k, xandy all increase by 20%
Answer:
The percentage increase in [tex]T[/tex] is 20 %.
Step-by-step explanation:
Let be [tex]T = \frac{k\cdot x}{y}[/tex], whose initial parameters are [tex]k = k_{o}[/tex], [tex]x = x_{o}[/tex] and [tex]y = y_{o}[/tex]. If these three parameters are increased by 20 %, then initial and final values of [tex]T[/tex] are, respectively:
Initial value
[tex]T_{i} = \frac{k_{o}\cdot x_{o}}{y_{o}}[/tex] (1)
Final value
[tex]T_{ii} = \frac{(1.2\cdot k_{o})\cdot (1.2\cdot x_{o})}{1.2\cdot y_{o}}[/tex]
[tex]T_{ii} = \frac{1.2\cdot k_{o}\cdot x_{o}}{y_{o}}[/tex] (2)
(1) in (2):
[tex]T_{ii} = 1.2\cdot T_{i}[/tex]
And the percentage increase in T is:
[tex]\%T = \frac{T_{ii}-T_{i}}{T_{i}}\times 100\,\%[/tex] (3)
[tex]\%T = \frac{1.2\cdot T_{i}-T_{i}}{T_{i}}\times 100\,\%[/tex]
[tex]\%T = 20\,\%[/tex]
The percentage increase in [tex]T[/tex] is 20 %.
Answer:
Step-by-step explanation:
Lets subsitute k, x and y as 100 to make it easier for us
So k = 100, x = 100, y = 100
Step 1 :- T = kx/y
- T = 100 * 100 / 100 = 100
Step 2 :- Increase by 20% = 100 * 20% = 20, 100 + 20 = 120
Step 3 :- Percentage Increase = Increased value OVER original calue MULTIPLIED by 100%
SO = ( 120 - 100 ) ,,,, 20/100 * 100% = 0.2* 100 = 20%

Renata and her family go through an average of more than 15 cans of sparkling water each day. They buy cases of 24 cans at $3.50 a case. Write an inequality for the number of cases they go through in 30 days.
Answer: The inequality required to express the above condition is x ≥ 18.75
Step-by-step explanation:Renata and her family go through an average of more than 15 cans of sparkling water each day.
The number of cases of 24 cans of sparkling water.
We can take the number of cases to be x.
Each case is said to cost $3.50.
An inequality for the number of cases that Renata's family go through in 24 days can be written as
x ≥ ⇒ x ≥ ⇒ x ≥ 18.75
Therefore the inequality required to express the above condition is
x ≥ 18.75

It is given that:
Greg sells the T-shirts for $7 each and the shorts for $14.
Greg can work 15 hours a day, at most it takes him 15 minutes to design a T-shirt and an hour to design a pair of shorts
Let s is the number of shorts
Let t is the number of t-shirts

s ≥ 12 - t
s ≤ 22 - t
0.25t + s ≤ 15
s ≥ 0; t ≥ 0
Thus, the inequalities s ≥ 12 - t, s ≤ 22 - t, 0.25t + s ≤ 15, s ≥ 0; t ≥ 0 representing the scenario provided option (A) is correct.

Which set of measurements could represent the three sides of a triangle?
O 2 cm, 3 cm, 6 cm
O 1 cm, 4 cm, 6 cm
O 8 cm, 9 cm, 10 cm
6 cm, 10 cm, 18 cm
Answer:
The side lengths of a right triangle is 11cm, 60cm and 61cm, that could be selected from the given measurements.
Step-by-step explanation:
The measurements are,
7cm, 11cm, 54cm, 60cm, 61cm, 65cm
Step:1
To check the right angle triangle, Pythagorean theorem can be used.
For a Pythagorean theorem,
..........................(1)
The side values are lower than the hypotenuse,
...................................(2)
Where,
a,b - side values
c - Hypotenuse
For right angle triangle, c > a, b
Alternative : 1
Take, a = 7cm, b = 11cm
From eqn (2),
= = 13.04
The above value is not equal to the any one of the values of ( 54cm. 60cm, 61cm, 65cm ), So its not an sides of right triangle.
Alternative : 2
Take, a = 7cm, b = 54cm
From eqn (2),
= = 54.45
The above value is not equal to the any one of the values of (60cm, 61cm, 65cm ), So its not an sides of right triangle.
Alternative : 3
Take, a = 7cm, b = 60cm
From eqn (2),
= = 60.406
The above value is not equal to the any one of the values of (61cm, 65cm ), So its not an sides of right triangle.
Alternative : 4
Take, a = 7cm, b = 61cm
From eqn (2),
= = 61.40
The above value is not equal to the values of (65cm ), So its not an sides of right triangle.
Alternative : 5
Take, a = 11cm, b = 54cm
From eqn (2),
= = 55.1089
The above value is not equal to the any one of the values of (60cm, 61cm, 65cm ), So its not an sides of right triangle.
Alternative : 6
Take, a = 11cm, b = 60cm
From eqn (2),
= = 61
The above value is equal to the values of (61cm ), So its an sides of right triangle. The three sides are 11, 60 and 61.
Step:2
Check for solution,
Result:
The side lengths of a right triangle is 11cm, 60cm and 61cm, that could be selected from the given measurements.
Step-by-step explanation: The side lengths of a right triangle is 11cm, 60cm and 61cm.
