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°.

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

Answer:

the probability of exactly 4 out of next 7 individuals that the sociologists survey earning over $50000 is given by

= [tex]\binom{7}{4} \cdot (0.3)^4(0.7)^{7-4}[/tex] = 0.09724

Step-by-step explanation:

i) This problem is solved by using the Binomial Probability distribution as the sample size is less than 30.

ii) The sample size is 7

iii) It is given that the probability of an individual earning over $50000 is 30% or 0.3 and therefore the probability of an individual not earning over $50000 is ( 1 - 0.3) = 0.7

iv) Therefore the probability of exactly 4 out of next 7 individuals that the sociologists survey earning over $50000 is given by

= [tex]\binom{7}{4} \cdot (0.3)^4(0.7)^{7-4}[/tex] = 0.09724

The series in sigma notation is:  representing terms increasing by 4 starting from -5.

To represent the series in sigma notation, let's first examine the pattern of the terms.

The given series starts with -5 and each subsequent term increases by 4. We can express this pattern using the formula:

[tex]\[ a_n = -5 + (n - 1) \times 4 \][/tex]

Here, [tex]\( a_n \) represents the \( n \)th term of the series[/tex].

Now, let's break down the components of the formula:

-[tex]\( -5 \) is the initial term of the series.- \( (n - 1) \) accounts for the position of each term in the series. When \( n = 1 \), \( (n - 1) = 0 \), so the first term is \( -5 \). As \( n \) increases, \( (n - 1) \) increases by 1, causing the series to increase by 4 each time.- \( 4 \) is the common difference between consecutive terms in the series.[/tex]

Next, we represent the series using sigma notation:

[tex]\[ \sum_{n=1}^{5} (-5 + (n-1) \times 4) \][/tex]

This notation indicates that we sum up the expression [tex]\( -5 + (n-1) \times 4 \) for \( n \)[/tex] ranging from 1 to 5, which covers all the terms of the given series.

In summary, the series is represented in sigma notation as described above, capturing the pattern of increasing terms starting from -5.

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

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

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

30 cm on the smaller figure corresponds to 12 meters on the larger figure.

We can write the ratio   30 cm : 12 m

If we divide both parts by the GCF 6 then,

30/6 = 5

12/6 = 2

This means the ratio  30 cm : 12 m  reduces to 5 cm : 2 m

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.

115-69/115*100

The percentage decrease is 40% if the price of an item yesterday was 115. Today the price fell to 69.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

The price of an item yesterday was 115. Today the price fell to 69.

The difference in price = 115 - 69 = 46

Percentage decrease = (46/115)×100 = 40%
