Can somebody answer this?

Answer:

Option (3)

Step-by-step explanation:

Given expression represents the sum of k terms of a geometric sequence.

[tex]\sum_{k=1}^{9}2(4)^{k-1}[/tex]

Since, formula to calculate the sum of a geometric sequence is given by,

[tex]\sum_{n=1}^{n}a(r)^{n-1}=\frac{a(1-r^n)}{1-r}[/tex]

By this formula,sum of 9 terms of the given sequence will be,

[tex]\sum_{k=1}^{9}2(4)^{k-1}=\frac{2(1-4^9)}{1-4}[/tex]

Therefore, Option (3) will be the answer.

Answer: 6951/10000

Step-by-step explanation:

Answer:

6951/10000

Step-by-step explanation:

This cannont be simplified anymore.

The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.

We are provided with the equation V = 5000[tex]e^{0.05t}[/tex]

The equation can be simplified as

V = 5000 e0* (0.05t)

V= 250t

This linear equation can be plotted for different values of t which are

If t=0, V = 0

If t=1, V = 250

If t=2, V = 500

If t=3, V = 750

If t=4, V = 1000

If t=5, V = 1250

If t=6, V = 1500

If t=7, V = 1750

If t=8, V = 2000

If t=9, V = 2250

If t=10, V = 2500

If t=11, V = 2750

If t=12, V = 3000

If t=13, V = 3250

If t=14, V = 3500

If t=15, V = 3750

If t=16, V = 4000

If t=17, V = 4250

If t=18, V = 4500

If t=19, V = 4750

If t=20, V =5000

Now, we just have plot these 20 coordinates

The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.

A linear equation is an equation with the maximum degree of one. This means that in a linear equation, no variable has an exponent greater than 1. A linear equation's graph is always a straight line.

Answer:

a. (92.4, 94.8)

Step-by-step explanation:

Given that:

Mean (m) = 93.6

Standard deviation (σ) = 4.2

Sample size (n) = 34

α = 90%

Confidence interval around sample mean :

Mean ± Zstatistic * s/√n

Z0.90 = 1.645 (Z probability calculator)

s / √n = 4.2 / √34 = 0.7202940

Lower limit = 93.6 - (1.645 * 0.7202940) = 92.41511637 = 92.4

Upper limit = 93.6 + (1.645 * 0.7202940) = 94.78488363 = 94.8

Answer:

b/2 + 7.4 = 1.4 thus D. is the answer

Step-by-step explanation:

Solve for b:

b/2 + 7.4 = 1.4

Put each term in b/2 + 7.4 over the common denominator 2: b/2 + 7.4 = b/2 + 14.8/2:

(b/2 + 14.8/2) = 1.4

b/2 + 14.8/2 = (b + 14.8)/2:

((b + 14.8)/2) = 1.4

Multiply both sides of (b + 14.8)/2 = 1.4 by 2:

(2 (b + 14.8))/2 = 2×1.4

(2 (b + 14.8))/2 = 2/2×(b + 14.8) = b + 14.8:

b + 14.8 = 2×1.4

2×1.4 = 2.8:

b + 14.8 = 2.8

Subtract 14.8 from both sides:

b + (14.8 - 14.8) = 2.8 - 14.8

14.8 - 14.8 = 0:

b = 2.8 - 14.8

2.8 - 14.8 = -12:

Answer: b = -12

Michael drove 1125 miles and paid $295 for renting the truck for 3 days

Rental company charges per day = $70

Rental company charges per mile = $0.20

Number of days truck is rented by Michael = 3 days

The total amount paid by Michael for the truck = $295

Let x be the number of miles Michael drives the truck

Formulating the equation using the information given in the question:

295 = 70 + 0.20(x)

295-70 = 0.20(x)

225 = 0.20(x)

x = 1125 miles

Therefore, the total miles driven by Michael is 1125 miles.

Michael paid $295 for driving the truck for 1125 miles and renting it for 3 days.

Out of the following types of angles adjacent angles do not have equal measure.

Here, from the given figure, we can see that the 2 horizontal lines are parallel to each other and a transversal is drawn between them.

When 2 lines are parallel and joined by a transversal, any two pairs or alternate exterior angles, alternate interior angles and corresponding angles will be equal.

However, any to pairs of adjacent angle will not be equal. The sum of a pair of adjacent angles that lie on the straight line is 180°.

Here, one pair of adjacent angles is ∠1 and ∠2. Thus-

∠1 + ∠2 = 180

∠1 and ∠2 will be equal only when both of them are 90° each. Here, we are not given that they are 90.

Hence, out of the following types of angles adjacent angles do not have equal measure.
