Answer:

The average rate of change of [tex]f(x) = x^2 +6x+13[/tex]  is 12

The average rate of change of [tex]f(x) =- x^2 +6x+13[/tex] is 10

Step-by-step explanation:

The  average rate of change  of f(x) over an interval between 2 points (a ,f(a)) and (b ,f(b)) is the slope of the  secant line  connecting the 2 points.

We can calculate the average rate of change between the 2 points  by

[tex]\frac{f(b) - f(a)}{b -a}[/tex]-------------------(1)

(1) The average rate of change of the function [tex]f(x) = x^2 +6x+13[/tex]  over  the interval 1 ≤ x ≤ 5

f(a) = f(1)

[tex]f(1) = (1)^2 +6(1) + 13[/tex]

f(1) =1+6+13

f(a) =  20---------------------(2)

f(b) = f(5)

[tex]f(5) = (5)^2 +6(5)+13[/tex]

f(5) = 25 +30 +13

f(5) = 68-----------------------(3)

The average rate of change between (1 ,20) and (5 ,68 ) is

Substituting eq(2) and(3) in (1)

=[tex]\frac{f(5) - f(1)}{5-1}[/tex]

=[tex]\frac{68 -20}{5-1}[/tex]

= [tex]\frac{48}{4}[/tex]

=12

This means that the average of all the slopes of lines tangent to the graph of f(x) between  (1 ,20) and (5 ,68 ) is 12

(2) The average rate of change of the function  [tex]f(x) = -x^2 +6x+13[/tex] over  the interval -1 ≤ x ≤ 5

f(a)  = f(-1)

[tex]f(1) = (-1)^2 +6(-1) + 13[/tex]

f(1) =1-6+13

f(1) = 8---------------------(4)

f(b) = f(5)

[tex]f(5) = (5)^2 +6(5)+13[/tex]

f(5) = 25 +30 +13

f(5) = 68-----------------------(5)

The average rate of change between (-1 ,8) and (5 ,68 ) is

Equation (1) becomes

[tex]\frac{f(5) - f(-1)}{5-(-1)}[/tex]

On substituting the values

=[tex]\frac{68 - 8}{5-(-1)}[/tex]

=[tex]\frac{60}{5+1}[/tex]

=[tex]\frac{60}{6}[/tex]

= 10

This means that the average of all the slopes of lines tangent to the graph of f(x) between  (-1 ,8) and (5 ,68 ) is 10

The relationship between the distance traveled by a car and the amount of gas in the car is inverse. As the distance increases, the gas decreases

The relationship between the distance traveled by a car and the amount of gas in the car is inverse. This means that as one quantity increases, the other decreases. In this case, as the distance traveled by a car increases, the amount of gas in the car decreases, because the car uses gas to move. In other words, the more you drive, the less gas you have left in your car.

To rewrite the expression (y + 1) + 4 without using parentheses, we can distribute 4 to the terms inside the parentheses and then combine like terms.

To rewrite the expression without using parentheses, we can use the distributive property. The distributive property states that multiplying a number by a sum is the same as multiplying the number by each term in the sum and then adding them together. In this case, we have (y + 1) + 4, and we can distribute the 4 to both terms inside the parentheses. So, (y + 1) + 4 can be rewritten as y + 1 + 4.Next, we can combine like terms. The terms y and 1 do not have any common variable factors, so they cannot be combined. However, 1 and 4 are both constants, so they can be added together to give us 5. Therefore, y + 1 + 4 simplifies to y + 5.

So, the expression (y + 1) + 4 can be rewritten as y + 5.

Answer:

28.71 is 435% of 6.6

Step-by-step explanation:

100%/x%=6.6/28.71

(100/x)*x=(6.6/28.71)*x       - we multiply both sides of the equation by x

100=0.229885057471*x       - we divide both sides of the equation by (0.229885057471) to get x

100/0.229885057471=x

435=x

x=435

Explanation

To work out how many times greater something is compared to another, we have to divide the larger number by the smaller

To put it more simply, imagine you had 30 apples and I had 6. To work out how many times greater your apple collection was than mine, you would divide your 30 by my 6, and find that you had 5 times as many apples as me (30 ÷ 6 = 5).

The principle is the same here, how many more viruses (3 x 10⁹) are there compared to protozoa (5 x 10⁵)?

We do 3 x 10⁹ ÷ 5 x 10⁵

3 x 10⁹ = 3,000,000,000

5 x 10⁵ = 500,000

3,000,000,000 ÷ 500,000 = 6,000 times more

Answer:

Step-by-step explanation:

∠AOB = 90 degree.

∠BOC = 52 degree.

Arc CDE = 180 degree, since CE is the diameter.

Hence, Arc EAC = 180 degree.

Besides, Arc EAC = Arc EA + Arc AB + Arc BC = Arc EA + 90 + 52 = Arc EA + 142.

Thus, Arc EA = 180 - 142 = 38 degree.

Arc ADC = 180 + 38 = 218 degree.

Answer: 2y + 11x = -104

Step-by-step explanation:

The formula for calculating equation of line given two points is :

[tex]\frac{y-y_{1}}{x-x_{1}}[/tex] = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]x_{1}[/tex] = -10

[tex]x_{2}[/tex] = -8

[tex]y_{1}[/tex] = 3

[tex]y_{2}[/tex] = -8

substituting the values into the formula , we have :

[tex]\frac{y-3}{x-(-10)}[/tex] = [tex]\frac{-8-3}{-8-(-10)}[/tex]

[tex]\frac{y - 3}{x + 10}[/tex] = [tex]\frac{-11}{2}[/tex]

2(y - 3 ) = -11 ( x +10 )

2y - 6 = -11x - 110

2y + 11x = -110 + 6

2y + 11x = -104

Therefore : the equation of the line in standard form is 2y + 11x = -104

Answer:

Step-by-step explanation:

The required difference is 160-yard average drives after two lessons.

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been given that before lessons, her drive averaged 240 yards.

Here her drive average = 240 yards

After her first lesson, her drives increase by 25%.

Therefore her drive 2 = 240 + 0.25(240) = 320 yards

After her second lesson, they increase another 25%.

Therefore her drive 3 = 320 + 0.25(320) = 400 yards

So, the required difference in yards of average drives after two lessons

⇒ 400 - 240 = 160 yards

Answer:

[tex]m\angle CAB=102\dfrac{6}{7}^{\circ}\\ \\m\angle ABC=51\dfrac{3}{7}^{\circ}\\ \\m\angle ACB=25\dfrac{5}{7}^{\circ}[/tex]

Step-by-step explanation:

AK is angle A bisector, then

[tex]m\angle BAK=m\angle KAC=x^{\circ}[/tex]

BL is angle B bisector, then

[tex]m\angle ABL=m\angle CBL=y^{\circ}[/tex]

Consider triangle ABL. The sum of the measures of all interior angles in this triangle is [tex]180^{\circ},[/tex] then

[tex]m\angle BAL+m\angle ALB+m\angle LBA=180^{\circ}\\ \\2x+2y+y=180\\ \\2x+3y=180[/tex]

Consider triangle ABK. In this triangle,

[tex]m\angle AKB=180^{\circ}-2x^{\circ} \ [\text{Supplementary angles}][/tex]

The sum of the measures of all interior angles in this triangle is [tex]180^{\circ},[/tex] then

[tex]m\angle BAK+m\angle AKB+m\angle KBA=180^{\circ}\\ \\x+(180-2x)+2y=180\\ \\2y-x=0[/tex]

Hence,

[tex]x=2y\\ \\2(2y)+3y=180\\ \\4y+3y=180\\ \\7y=180\\ \\y=\dfrac{180}{7}=25\dfrac{5}{7}\\ \\x=\dfrac{360}{7}=51\dfrac{3}{7}[/tex]

Find the measures of the triangle ABC:

[tex]m\angle CAB=2x^{\circ}=102\dfrac{6}{7}^{\circ}\\ \\m\angle ABC=2y^{\circ}=51\dfrac{3}{7}^{\circ}\\ \\m\angle ACB=180^{\circ}-102\dfrac{6}{7}^{\circ}-51\dfrac{3}{7}^{\circ}=25\dfrac{5}{7}^{\circ}[/tex]

The problem is asking to find all angles of an isosceles triangle ABC with angle bisectors AK and BL. The given conditions imply that the triangle has angles of 45°, 45°, and 90°.

The student is asking about an angle bisector problem in triangle geometry. In triangle ABC, the angle bisectors AK and BL are drawn such that m∠BAC = m∠AKC and m∠ABC = m∠ALB. To solve this problem, we need to use the properties of angle bisectors and triangles.

Since AK is an angle bisector, it bisects ∠BAC into two equal angles. Similarly, BL bisects ∠ABC into two equal angles. We also know that the sum of angles in a triangle is 180 degrees.

Let's denote m∠BAC and m∠AKC as 'x'. Similarly, let's denote m∠ABC and m∠ALB as 'y'. Since AK and BL are bisectors, m∠BAK = m∠CAK = x and m∠ABL = m∠CBL = y. Hence, ∠ACB would be 180 - 2x - 2y (sum of angles in a triangle).

We are given that m∠BAC is equal to m∠AKC and m∠ABC is equal to m∠ALB. This implies that the triangle is isosceles with the following angle measurements: m∠BAC = m∠ABC = x (equal base angles in an isosceles triangle), and m∠ACB = 180 - 2x.

Now, since m∠BAC and m∠ABC are equal, we can say that 2x + (180 - 2x) = 180. Simplifying, we find that x = 45 degrees, and thus, all angles of triangle ABC are 45°, 45°, 90°.
