Identify the type of segments as 2 CHORDS, 2 SECANTS, OR SECANT AND TANGENT. Then, find the variable.

Answer:

a and b I know for sure, im not sure about the others sorry

Answer:

Expand it.

(1+2i)^3 is equal to (1+2i)(1+2i)(1+2i).

Multiply everything out (being sure to multiply every term. (1+2i) * (1+2i) = 1+2i+2i+4i^2.

i is the square root of negative one, so i^2 is just -1. 1+2i+2i-4 is what you get from the first two, so now simplify that:

1-4 + 2i+2i = (-3+4i) and now multiply that by (1+2i):

(-3+4i) * (1+2i) = -3 - 6i +4i +8i^2.

Simplify again, and the answer is: -11-2i

Step-by-step explanation:

I hope this helps - really my only tip is don't spend time thinking about what i is, that just hurts your brain. Just remember that i^2 is equal to negative one, and treat it like regular multiplication and you will be fine.

Step-by-step explanation:the formula for solving time is 100 * 40 naira / / 200 * 15

Answer:

18.4 years

Step-by-step explanation:

The compound interest formula:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

For this problem we have

[tex]P= 2000\\r= 0.06\\n= 4\\A= 2000(3)= 6000[/tex]

We plug our numbers...

[tex]6,000= 2,000(1+\frac{0.06}{4} )^{4t} \\[/tex]

Then divide

[tex]6,000/2,000=3[/tex]

[tex]3= (1.015)^{4t}[/tex]

Apply log both sides

[tex]3log=(1.015) 4tlog[/tex]

The number of times Jennifer rolls a number less than 3 in a number cube when she rolls it 60 times is 40.

The probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

The probability of rolling a number less than 3 on a number cube is 2/6.

[tex]P( > 3)=\dfrac{2}{6}[/tex]

Here, the Jennifer rolls a number cube 60 times. Thus, the number of times she rolled the number less than 3 in this cube is,

Step-by-step explanation:

on the coordinate grid you can imagine a right-angled triangle.

the direct distance between the 2 points is the Hypotenuse (the baseline opposite of the 90° angle).

and the x-coordinate difference and the y- coordinate difference of the 2 points are the 2 legs.

we can then use Pythagoras

c² = a² + b²

with c being the Hypotenuse, a and b being the legs.

so,

distance² = (8-0)² + (2-0)² = 64 + 4 = 68

distance (= length ab) = sqrt(68) = sqrt(4×17) = 2×sqrt(17) =

Answer:

6 pelicans

Step-by-step explanation:

Let x = number of pelicans

Cody saw 4 times as many seagulls as pelicans:

⇒ number of seagulls = 4x

Total of 30 birds:

⇒ seagulls + pelicans = 30

⇒ 4x + x = 30

⇒ 5x = 30

⇒ x = 6

Therefore, there were 6 pelicans (and 24 seagulls).

Answer:

y = (1/5)x - 12/5

Step-by-step explanation:

First, you need to find the slope (m). This can be done by using the given points and the following equation.

y₁ - y₂ = m(x₁ - x₂)

-3 - (-2) = m(-3 - 2)

-1 = -5m

1/5 = m

Next, you need to find the y-intercept (b). You can do this by using the slope and the values of a point in the following equation.

y = mx + b

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

-2 = 2/5 + b

-2.4 = b

-12/5 = b

Putting the information together, you are left with your final equation.

y = (1/5)x - 12/5

Answer:

C is the only correct answer

Answer:

90°

Step-by-step explanation:

This is important to remember, the three interior angles will always have a sun of 180.

knowing this it’s pretty basic math

a + b + c = 180

33 + 57 + c = 180

90 + c = 180

[subtract 90 from each side (90 cancels out)]
c = 90°

…

Check
- > 33 + 57 + 90 = 180

33 + 147 + = 180

180 = 180

The sample size for part (a) is 540, and the sample size for part (b) is 543 if the margin of error is 0.05.

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

[tex]\rm MOE = X \times \dfrac{s}{\sqrt{n}}[/tex]

Where   Z is the z-score at the confidence interval

           s is the standard deviation

           n is the number of samples.

We know:

[tex]\rm MOE =Z \times\sqrt{ \dfrac{pq}{n}}[/tex]

We have MOE = 0.05, p = 46% = 0.46,

q = 1-p = 1-0.46 = 0.54

Z at 0.02(because 98% level of confidence) = 2.33

Plug this value in the formula we get:

[tex]0.05=2.33\times \sqrt{\dfrac{0.46\times 0.54}{n}}[/tex]

After solving:

n = 539.41 ≈ 540

If no estimate is given:

p = 0.5 and q = 0.5

[tex]0.05=2.33\sqrt{\dfrac{0.5\times 0.5}{n}}[/tex]

n = 542.89 ≈ 543

Thus, the sample size for part (a) is 540, and the sample size for part (b) is 543 if the margin of error is 0.05.

Both ∠AKL and ∠AKC have a value of 45 degrees. The rationale is that the regular polygons BKLC (rectangle) and ABCD are bisected by lines AK and KC respectively. Since the sum of angles in a right angle is 90°, thus half of that is 45°.

A regular polygon is a polygon that has two dimensions and can be made or drawn using at least three lines joined together.

Because, the sum of angles in a right angle is 90° and half of that is 45°, we can thus conclude that the values of ∠AKL and ∠AKC are both 45° each.

The actual distance is: 17500mm

A map scale is used to show the relationship between the distance on the map and the distance on the earth.

Analysis:

The scale 1:500 is a reduction scale, it means every 1 mm on the map represents 500mm on the ground

So if 1mm on the map represents 500mm on the ground, then 35mm on the map would be 500 x 35 = 17500mm

In conclusion, the actual distance between the two hidden treasures is 17500mm.

If the mass of the object is 900 g and the volume is 1,875 cm³. Then the density of the object is 0.48 g/cm³.

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

Density = mass / volume

An object has a mass of 900 g and a volume of 1,875 cm³.

Then the density will be

Density = 900/1875

Density = 0.48 g/cm³

The probability is that a randomly selected tire that has a depth less than 0.50 mm will be 0.085121.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

A tire company measures the tread on newly-produced tires and finds that they are normally distributed with a mean depth of 0.98mm and a standard deviation of 0.35mm.

Then the probability is that a randomly selected tire has a depth less than 0.50 mm will be

The value of the z-score will be

z = (0.50 - 0.98) / 0.35

z = -1.3714

Then the probability will be

P(x < 0.50) = P(z < -1.3714)

P(x < 0.50) = 0.085121
