Given:

[tex]m\angle ABC=46^\circ[/tex]

BD bisects angle ABC.

To find:

The [tex]m\angle ABD[/tex].

Solution:

It is given that, BD bisects angle ABC. It means, BD divides the angle ABC is two equal parts. So,

[tex]m\angle ABD=m\angle DBC=\dfrac{\angle ABC}{2}[/tex]

We need to find [tex]m\angle ABD[/tex], so

[tex]m\angle ABD=\dfrac{\angle ABC}{2}[/tex]

[tex]m\angle ABD=\dfrac{46^\circ}{2}[/tex]

[tex]m\angle ABD=23^\circ[/tex]

Therefore, the [tex]m\angle ABD[/tex] is 23°. Hence first option is correct.

Answer:

Thank you for your question. The options are missing: here are the missing options:

f(–3) = 8

f(3) = 5

f(8) = 0

f(–6) = 10

Answer

When a function f(x) is defined by ordered pairs (x,y), we can say that f(x) = y. Since it's a function, for every given x, there should only be one value for y.

(-6,10)

(0 , 4)

(1, -5)

(2, -1)

(8 ,-3)

it is not a line because the slopes are different

The correct answer is f(–6) = 10

Using the ordered pairs given, it is found that the true statement regarding the function is: f(–6) = 10​

A function y = f(x) is composed by a sequence of ordered pairs (x, f(x)).

In this problem, the pairs are as follows: {(8, –3), (0, 4), (1, –5), (2, –1), (–6, 10)}, hence:

Hence the correct statement is f(–6) = 10​.

Complete Question

Bacteria culture A culture of the bacterium Rhodobacter sphaeroids initially had 30 bacteria and t hours later increases at a rate of 2e^2t 1 bacteria per hour. Find the population size after four hours

Answer:

3010

Step-by-step explanation:

We were given the rate: 2e^2t

Step 1

We would integrate

P = Population

dP/dt = 2e^2t

dP =( 2e^2t) dt

∫dP = ∫ 2e^2t dt

P(t) = (2e^2t)/2 + C

P(t) = e^2t + C

Step 2

We solve for C

The culture initially has 30 bacteria

When t = 0

P(0) = 30

P(0) = e^2t + C

30 = e^2× 0 + C

30 = 1 + C

C = 30 - 1

C = 29

Step 3

Find the population size after four hours

t = 4, C = 29

P(t) = e^2t + C

P(4) = e^2 × 4 + 29

P(4) = e^8 + 29

P(4) = 3009.957987

Approximately = 3010 bacteria

Step-by-step explanation:

Answer:

A sample of 307 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this question, we have that:

We dont know the true proportion of women police officers, so we use [tex]\pi = 0.5[/tex], which is when the largest sample size would be needed.

92% confidence level

So [tex]\alpha = 0.08[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.08}{2} = 0.96[/tex], so [tex]Z = 1.75[/tex].

How large should a sample be if the margin of error is .05 for a 92% confidence interval

We need a sample of n, and n is found when [tex]M = 0.05[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 1.75\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.05\sqrt{n} = 1.75*0.5[/tex]

[tex]\sqrt{n} = 17.5[/tex]

[tex](\sqrt{n})^2 = (17.5)^2[/tex]

[tex]n = 306.25[/tex]

Rounding up

A sample of 307 is needed.

Answer: (C)

Step-by-step explanation:

Answer:

x=6

Take 2 to the other side, the sign becomes negative. You're then left with 5x is less than 30. After that just divide both sides with 5 so that you're left with x.

The value of  x is less than 6

Inequality shows the relationship between two values in an algebraic equation that are not equal.

The given inequality is 5x + 2 < 32

Subtract -2 from both sides of the inequality then we get

5x < 30

Next, divide both sides by 5, then we get the range of x.

i.e x < 6

The solution to the given inequality  is x < 6 .
