Help please algebra one ten points !!!

Answer:

R = 1

I = [-1, 1)

Step-by-step explanation:

Use the ratio test:

lim(n→∞)│aₙ₊₁ / aₙ│

lim(n→∞)│[xⁿ⁺¹ / (8(n+1) − 1)] / [xⁿ / (8n − 1)]│

lim(n→∞)│[xⁿ⁺¹ / (8n + 7)] × [(8n − 1) / xⁿ]│

lim(n→∞)│[x (8n − 1) / (8n + 7)]│

lim(n→∞)│[(8n − 1) / (8n + 7)]││x│

│x│

The series converges if the limit is less than 1.

│x│< 1

So the radius of convergence is 1.

Solving for x:

-1 < x < 1

Check the endpoints.

If x = -1, the series is ∑ (-1)ⁿ / (8n − 1), which converges.

If x = 1, the series is ∑ 1 / (8n − 1), which diverges.

So the interval of convergence is [-1, 1).

Answer:

642000000000000000000000 kg

Step-by-step explanation:

The approximate mass of Mars is 6.42x10^23 kilograms. It is given in scientic notation.

We need to write the mass in standard notation. It is the normal way of writing any number. To write it in standard form, we move the decimal to the right side.

The standard form will be :

6.42x10^23 kg = 642000000000000000000000 kg

Hence, this is the required solution.

Hey there!

Looking through figure; we find that,

angle 7 + 38° = 180° { Being linear pair}

Or, angle 7 = 180° - 38°

Angle 7 = 142°

Therefore, the measure of angle 7 is 142°.

Answer:

Uhhh what model? Bruh 12/3 is just 4

Step-by-step explanation:

Answer:

South =34.18 miles

East=  49.12miles

Step-by-step explanation:

We begin by calculating the distance covered in 7n hours

that is from 12 pm to 7pm which is 7 hours

so time t= 7 hours

speed= 40 miles per hours

we know that speed= distance/time

let the distance be x

40=x/7

x=40*7

x=28miles

(a) many miles south and how many miles east will the boat have traveled at 7 pm

applying SOH CAH TAO we have

For the  south  CAH

cos Ф=hyp/adj

hyp= 28 mile

Ф= 35°

cos 35= 28/adj

0.819=28/adj

adj=28/0.819

adj=34.18 miles

For the  East SOH

sin Ф=hyp/opp

hyp= 28 mile

Ф= 35°

sin 35= 28/opp

0.57=28/opp

opp=28/0.57

opp=49.12miles

Answer:

The pie chart is missing, so I looked for similar questions (see attached image):

(a) Which color was chosen by approximately one-eighth of the customers?

(b) Approximately what percentage of the customers chose White or Blue?

(c) If 24% of the customers chose Black, approximately what percentage chose Other?

The easiest way to solve this is to print the image and use a protractor. If you want to calculate the area for blue, just measure the angle, e.g. ± 55°, then divide by 360° = 0.1528 = 15.28%.

Answer:

Step-by-step explanation:

Given the height of the drone modelled by the equation:

h(t)=-3t^2+12t+96

a) Rewriting this in a factored form.

From the equation, we can see that -3 is the greatest common factor. The equation therefore becomes:

h(t)= -3(t^2-4t-32)

Hence the function can also be written as h(t)= -3(t^2-4t-32)

b) The drone landed on the ground at when h(t) = 0. Substitute h(t) = 0 into the expression  h(t)= -3(t^2-4t-32)

0 = -3(t^2-4t-32)

Divide through by -3

(t^2-4t-32) = 0

Factorize

t²+8t-4t-32 = 0

t(t+8)-4(t+8) = 0

(t-4)(t+8) = 0

t-4 = 0 and t+8 = 0

t = 4 and t = -8

Time can't be negative:

t = 4minutes

Hence it took the drone 4 minutes take off to land on the ground

Answer: 1) h(t)= -3 (t-8) (t+4)

2) 8 mins.

Step-by-step explanation: This is the correct answer. I tried.

Answer:

The correct option is B.

Step-by-step explanation:

The median (m) is a measure of central tendency. To obtain the m, we assemble the data in arising order. If the data is odd, the m is the mid-value. If the data is even, the m is the arithmetic-mean of the two mid-values.

The mean is the average value of the data set. It is computed by dividing the sum of all the values in data set by the number of values.

So, the mean considers all the values in the data set. But the median considers only one value.

It is provided that the clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest  employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000.

The highest salary will be taken into account while the computation of mean. But it would not be considered while determining the median.

So, the median salary will remain same.  But the mean salary will change.

And since the highest salary is increasing from $150,000 to $1,500,000 the mean will also increase.

Thus, the correct option is B.

Have A Blessed Day!

The answers are To find 50% of a number, divide the number by 2, To find 25% of a number, divide the number by 4 and To find 10% of a number, divide the number by 10.

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, by what we should divide to the give expression to get 25%, 50% and 10%

Converting the percentage into fractions,

To change the percentage to a fraction, put the percentage number in the numerator and 100 in the denominator.

50% = 50/100 = 1/2, so we will divide it by 2,

25% = 25/100 = 1/4, so we will divide it by 4,

10% = 10/100 = 1/10, so we will divide it by 10.

Hence, The answers are To find 50% of a number, divide the number by 2, To find 25% of a number, divide the number by 4 and To find 10% of a number, divide the number by 10.

Answer:

Answer:  The correct option is (a) 21.3 dL.

Step-by-step explanation:  We are given to find the number of deciliters that are equivalent to 9 cups.

Given that,

1 cup = 0.237 liters.

We know that

1 liter = 10 deciliters. So, we get

0.237 liters = 0.237 × 10 deciliters = 2.37 deciliters.

This implies that

1 cup = 2.37 deciliters.

Therefore, we get

9 cups = 2.37 × 9 deciliters = 21.33 deciliters.

Rounding to nearest tenth, we get

Thus, 9 cups are equivalent to 21.3 deciliters.

Option (a) is CORRECT.
