The value of a is 92.17 when b=3 and c=7.

Jointly proportional refers to a relationship between two or more variables in which all of the variables increase or decrease together in the same ratio. For example, if one variable doubles, the other variables double as well.

The variable a is jointly proportional to b and c, which means that a = k*b*c, where k is the constant of proportionality.

We can use the given values of a, b, and c to find the value of k:
79 = k*6*3
79 = 18k
k = 79/18

Now that we know the value of k, we can use it to find the value of a when b=3 and c=7:
a = k*b*c
a = (79/18)*3*7
a = 92.17

Therefore, the value of a when b=3 and c=7 is 92.17.

The length and width of the rectangle are 10 and 3, respectively.

Let's use "l" to represent the length of the rectangle and "w" to represent the width. From the problem statement, we've got portions of information:

The perimeter is 26. The formulation for the perimeter of a rectangle is P = 2l + 2w. So we are able to write:

2l + 2w = 26

The length is four extra than twice the width. In equation shape:

l = 2w + four

Now we can use substitution to resolve for the length and width. we will alternative the expression 2w + 4 for l within the first equation:

2(2w + 4) + 2w = 26

Simplifying:

4w + 8 + 2w = 26

6w + 8 = 26

6w = 18

w = 3

So the width of the rectangle is three. To discover the length, we're going to substitute w = 3 into the equation for l:

l = 2w + 4 = 2(3) + 4 = 10

So the length of the rectangle is 10.

Thus, the length and width of the rectangle are 10 and 3, respectively.

As per the given distance, the maximum height reached by the football is 15.4 yards.

To find the maximum height reached by the football, we need to find the vertex of the parabolic path. The vertex of a parabola represents the highest point on the path. In this equation, the vertex can be found by using the formula:

x = -b / 2a

where a, b, and c are coefficients of the quadratic equation ax² + bx + c = 0.

By comparing the given equation with the standard form of the quadratic equation (y = ax² + bx + c), we can find that a = -0.035 and b = 1.4.

Substituting these values in the formula, we get:

x = -1.4 / 2(-0.035)

x = 20

This means that the maximum height is reached when the football has traveled a distance of 20 yards. To find the maximum height, we need to substitute this value of x back into the original equation:

The average rate of change of Q(x) from x=3 to x=3+h for h=0.2 is 21.2.

To find the average rate of change of Q(x) from x=3 to x=3+h, we need to plug in the values of h and a into the difference quotient and simplify.

When h=0.2, the difference quotient becomes:

(Q(3+0.2)−Q(3))/0.2

= (Q(3.2)−Q(3))/0.2

= ((3(3.2)^2+5(3.2)+10)−(3(3)^2+5(3)+10))/0.2

= ((30.24+16+10)−(27+15+10))/0.2

If Ranjit made pies for a fundraiser. The number of pies Ranjit made for the fundraiser is: 26.

Let p = total number of pies that Ranjit made

Let s = Total number of slices of pie that he made.

Since each pie is cut into 8 slices, we have:

s = 8p

After the first day of the fundraiser, Ranjit sold 10 slices, which means he had s - 10 slices left. Since he had 2 whole pies left, we know that he had 16 slices left. Therefore:

s - 10 = 16

Substituting s = 8p, we get:

8p - 10 = 16

Adding 10 to both sides, we get:

8p = 26

Dividing both sides by 8, we get:

p = 3.25

This means that Ranjit made 3.25 pies for the fundraiser.

The total number of slices would have been:

s = 8p = 8(3.25) = 26

On the first day, he sold 10 slices, which means he had 16 slices left. This matches our initial calculation and confirms that our solution is correct.

Answer: 5.25

Step-by-step explanation:

     Next, we are finding 15% of 35. In mathematical terms, "of" usually represents multiplication. We will multiply 0.15 by 35 to find 15% of 35.

0.15 * 35 = 5.25

The difference in area between a circle with a radius of 10cm and regular pentagon inscribed in it is  142cm².

The difference in area between a circle with a radius of 10cm and a regular pentagon inscribed in it can be found by first finding the area of the circle and then the area of the pentagon, and then subtracting the two values.

To find the area of the circle, we use the formula

A = πr²,

where r is the radius of the circle. In this case, r = 10cm, so the area of the circle is:

A = π(10cm)²
A = 100π cm²

To find the area of the regular pentagon, we can use the formula

A = (1/4)n*a² * cot(π/n),

where n is the number of sides of the polygon and a is the length of one side. Since the pentagon is inscribed in the circle, we can use the radius of the circle to find the length of one side of the pentagon.

The length of one side of the pentagon is:

a = 2r * sin(π/n)
a = 2(10cm) * sin(π/5)
a = 11.756cm

Now we can plug this value into the formula for the area of the pentagon:

A = (1/4)(5)(11.756cm)² * cot(π/5)
A = 172.047cm²

Finally, we can subtract the area of the pentagon from the area of the circle to find the difference in area:

Difference in area = 100π cm² - 172.047cm²
Difference in area = 314.159cm² - 172.047cm²
Difference in area = 142.112cm²

(a) Since Zul's password consists of 4 digits and the first three digits are 970, there is only one possible digit for the fourth digit. Thus, the probability to unlock the screen in one attempt is 1/10.

(b) If there are three 1s in the password, there is only one possible arrangement for the other digit. There are four places where the other digit can be placed, so there are four possible passwords. Thus, the probability to unlock the screen in one attempt is 4/10^4, which simplifies to 1/2500.

(c) If the last two digits are 00, there is only one possible arrangement for the first two digits. There are ten possible digits for the third digit and one possible digit for the fourth digit. Thus, the probability to unlock the screen in one attempt is 1/(101010*1), which simplifies to 1/1000.

Point D's coordinates are (-3, 3).

We may use the fact that the opposite sides of a parallelogram are parallel and the same length to get the coordinates of point D such that ABCD forms a parallelogram.

First, we may determine the segment AB's length and slope:

Length AB = sqrt((1 - (-1))² + (6 - (-2))²) = sqrt(64) = 8

Slope AB = (6 - (-2)) / (1 - (-1)) = 8/2 = 4

As AB and CD are parallel, CD's slope must likewise be 4.

Next, we may determine segment AB's midpoint, which will coincide with segment CD's midpoint:

Midpoint AB is equal to ((-1+1)/2, ((-2+6)/2)). (0,2)

Point D will therefore have the same coordinates as the point that is symmetric to point C around the centre of AB. The following is where to find this point:

Midpoint AB - C = (20-3, 22-1) = D = 2 * (-3, 3)

Hence, point D's coordinates are (-3, 3).
