Number of cartons of cloth face masks purchased will be 19  and number of cartons of  hand-sanitizer purchased will be 5.

We had given that Maleri Designs sells cartons of cloth face masks ($10) and cartons of hand-sanitizer ($4) on eBay.

Also given that Mod World, purchased 24 cartons.

Let number of cartons of cloth face masks be x and let number of cartons of  hand-sanitizer be y.

As total carton purchased is 24.

∴ x + y = 24 --(1)

also Mod World, purchased 24 cartons for $210.

∴ Also price of cartons of cloth face masks is $10 and cartons of hand-sanitizer is $4 which is buyed at $210.

∴ 10x + 4y = 210  --(2)

Now multiplying equation (1) by 10

∴ 10x + 10y = 240 --(3)

Now subtracting (2) from (3) by simplification

∴ y = 5

∴ x = 19

Number of cartons of cloth face masks purchased will be 19  and number of cartons of  hand-sanitizer purchased will be 5.

Based on the system of equations, the cost of using 19 HCF of water is $35.43

An equation is a mathematical statement that two or more values are equivalent.

Equations are stated to show that two mathematical expressions are equal using the equation sign (=).

Cost of using 17 HCF of water = $32.13

Cost of using 35 HCF of water = $61.83

Total cost of 17 HCF water = 17x + a

17x + a = 32.13 ... equation 1

Total cost of 35 HCF water = 35x + a

35x + a = 61.83 ... equation 2

35x + a = 61.83

-17x + a = 32.13

18x = 29.70

18x = 29.7

x = 29.7/18

x = 1.65

17x + a = 32.13 ... equation 1

17(1.65) + a = 32.13

28.05 + a = 32.13

a = 4.08 (32.13 - 28.05)

= 19(1.65) + 4.08

= $35.43

Thus, using the equations above, we can conclude that 19 HCF of water costs $35.43.

The equation of the parabola for the given points is y = -3x² + 7x + 1

Equation of the parabola

The standard form of the equation of a parabola is expressed as

y = f(x) = ax² + bx + c

where a, b, and c are constants and a ≠ 0.

Given,

Here we have the points (0, 1), (1, 5), (2, 3).

Now, we have to find the equation of the parabola.

Here we are given three coordinates (0, 1), (1, 5), and (2, 3) which lie on the parabola and which means that it satisfies the parabolic equation.

In order to find the values of a, b and c we need to formulate three equations using the three given points.

Since for the three unknowns a, b, and c, we will require three equations.

For that we have to take the Point (0,1) i.e. x = 0 and y = 1

Substituting the values of x and y in the standard parabola equation, then we get,

1 = a(0)² + b(0) + c

1 = 0 +  0 + c

c = 1 -------------------(1)

Next, we have to take the Point (1, 5) i.e. x = 1 and y = 5

Substituting the values of x and y in the standard parabola equation, then we get,

5 = a(1)² + b(1) + c

5 = a +  b + c

It can be written as,

a + b + c = 5 -----------------------------(2)

Finally, we have to take the Point (2, 3) i.e. x = 2 and y = 3

Substituting the values of x and y in the standard parabola equation, then we get,

3 = a(2)² + b(2) + c

3 = 4a +  2b + c

It can be written as,

4a + 2b + c = 3 -----------------------------(2)

Apply the value of c as 1 in equation (2), then we get,

a + b + 1 = 5

a + b = 4 ---------------------(4)

Similarly, apply the value of c on the equation (3), then we get,

4a + 2b + 1 = 3

4a + 2b = 2

Divide the equation by 2 on both sides, then we get,

2a + b = 1 --------------------(5)

Subtract equation (5) from equation (4),

(2a - a) +(b - b) = 1 - 4

a = -3

Apply the value of a in the equation (4) to get the value of b,

(-3) + b = 4

b = 7

Therefore, the equation of the parabola is

y = -3x² + 7x + 1

Answer:

Explanation:

We are given the equation for the height:

If we differentiate this equation, we get the equation of the velocity:

The problem tells us that the object hits the ground at a velocity of -25m/s. We can write this:

Where t0 is the time when the object hits the ground, and the velocity is -25m/s

Now, we can solve for v0:

And if we use this in the height h(t) equation, we can find the value of t0. At t0, the height is 0. Thus:

And solve:

Next, we can use the quadratic formula to solve this:

Let's see which of the two solutions is the time we are looking for.

Let's go back to our solution for v0:

If we use t0 = 0.43751 s:

This means that the initial velocity is negative, thus the object goes downwards. But, the problem tells us that initially the object is thrown upwards.

The correct value of t0 = 4.66 seconds

Now we can find v0:

Thus, v0 = 20.7 m/s

The balance after 6 months is 1197.04.

• x-intercept can be found by letting y equal to 0.

• y-intercept can be found by letting x equal to 0.

X intercept is the x-axis cutting point of the graph.

Y intercept is the y-axis cutting point of the graph.

The equation given is:

First, finding x intercept (let y = 0):

Second, find y intercept (let x = 0):

Hence,

Step-by-step explanation:

any linear function represents a straight line (hence the name) and is therefore of the structure

y = f(x) = ax + b

"a" is the slope of the line, and it is represented by the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another point.

"b" is the y-intercept (the y-value when x = 0).

so, let's look at the answer options :

A.

x = 0 gives us b (the y value) : 2

so, then for x = 1, y = 3 ?

3 = a×1 + 2

a = 1

now, the next point must be also on the same line for the whole function to be linear (and that means the equation has to be true for all numbers involved) :

x = 2, y = 6

6 = 1×2 + 2 = 4

6 is for sure NOT 4, so this is not a linear function.

it is actually y = x² + 2

B.

x = 0 gives us b : 1

for x = 1, y = 3 ?

3 = a×1 + 1

a = 2

again, the next point must be on the same line :

x = 2, y = 9

9 = 2×2 + 1 = 5

9 is for sure NOT 5, so this is not a linear function.

it is actuality y = 3^x.

C.

x = 0 gives us b : 0

for x = 1, y = 1 ?

1 = a×1 + 0 = a

a = 1

the next point :

x = 2, y = 4

4 = 1×2 = 2

4 is for sure NOT 2, so this is not a linear function.

it is actually y = x².

D.

x = 0 gives us b : 3

for x = 1, y = 9

9 = a×1 + 3

a = 6

the next point(s) must fit :

x = 2, y = 15

15 = 6×2 + 3 = 12 + 3 = 15

correct

x = 3, y = 21

21 = 6×3 + 3 = 18 + 3 = 21

correct

yes, this is a linear function.

it is y = 6x + 3

Given in the question,

The Richardson family needs 990272 per year to in their budget.

Mrs. Richardson works 22 hours a week.

Mr. Richardson works 40hours a week.

We need to calculate their hourly income.

Lets first calculate total weeks in a year.

We know that, a year has 365 days and a week has 7

So, total no. of weeks in a year = 365/7 = 52.143 weeks.

no. of weeks in a year = 52.143 weeks

Their weekly income = yearly income/no. of weeks in a year

So, weekly income = 990272/52.143

weekly income = 18991.466

Their hourly income = weekly income/working hours per week

Their weekly income is 18991.466 and,

working hours = 22 + 40 = 62 hours.
