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:

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

$25,000 / 100 then 250 x 32 then 8,000 x 75 to get $600,000

The amount of the tv in 3 years which depreciates at a rate of 4% per year is £708 .

We have given principal amount =  £800 , rate = 4% and time = 3 years .

Putting above values in equation (1) , we get

        [tex]A=800(1-\frac{4}{100} )^3\\A= 800(1 -0.04)^3\\A=800(0.96)^3\\A=800\times 0.88\\A= \£707.78[/tex]

Note that the minus sign is due to depreciation .

On rounding off , amount will be £708 .

Based on the number of throws Luke had and the percentage he made, the number he made was 50 throws.

There were 200 free throws in the season and Luke was able to make about 25% of them.

The formula to find this is therefore:

= Number of free throws x Percentage made

Solving gives:

= 200 x 25%

= 50 throws

Answer:

Between 2 & 3 seconds. Or we can write it as 2<t<3

Step-by-step explanation:

t = elapsed time in seconds

h(t) = height of the ball at time t

So we just need to replace h(t) with 100 and start to solve. In the end, the answer will be t=2, or t=3 or we can write it as 2<t<3. You can check it by plugging in the number into the equation.

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.

In terms of geometry, a sphere is described as a collection of points that are spaced apart by a specific amount. The supplied point is referred to as the sphere's center, and the given distance from the sphere's center to the collection of points that make up the sphere is referred to as the sphere's radius.

Many everyday things, including balls and globes, are spheres. Finding a sphere's radius and entering it into the straightforward formula V = [tex]\frac{4}{3}[/tex]π [tex]r^{3}[/tex] will allow you to determine its volume.

Given: The radius of the tennis ball is 2.1cm and the radius of the golf ball is 2.0cm. the formula is V=4πr(to the 3rd power) /3 .

To find: Volume of tennis ball and golf ball .

Formula used: V = [tex]\frac{4}{3}[/tex]π [tex]r^{3}[/tex] .

pi(π) =[tex]\frac{22}{7}[/tex] .

We are given that

Radius of the tennis ball = 2.1 cm

radius  of the golf ball =2.0 cm.

We need to find the volume of each ball

So , plugging the given values of radius in above formula

Volume of the tennis = [tex]\frac{4 * 22 * (2.1)^{3} }{3 * 7}[/tex] = 38.808 [tex]cm^{3}[/tex]

On simplification we get, volume of tennis ball = 38.808 [tex]cm^{3}[/tex]

Volume of the golf ball= [tex]\frac{4 * 22 * (2.0)^{3} }{ 3*7}[/tex] = 33.523[tex]cm^{3}[/tex]

On simplification we get, volume of golf ball = 33.523[tex]cm^{3}[/tex]

∴ The volume of tennis ball = 38.808[tex]cm^{3}[/tex]

Volume of golf ball = 33.523[tex]cm^{3}[/tex]

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.
