Actually Welcome to the concept of Geometric Progression.

So, we know that,

GP = a.r^(n-1)

here, a = 4 and r = -2

so we get as,

an = 4.(-2)^n-1

Option B.) is correct

Answer:

Step-by-step explanation:

                 |              1 -H        |       2-H          |       Total

Green       |           170            |          x           |       y

Total         |            430          |          v            |      852      

Correct choice is B

the answer to the question is 0.1

Answer:

1/10 or 0.1

Step-by-step explanation:

You first rewrite the problem as 2/5÷4/1. Then you flip the second fraction for multiplication: 2/5*1/4. Now you multiply both numerators and denominators to get a final total of 2/20 which equals 1/10 or 0.1.

Answer:

b = 77

Step-by-step explanation:

a² + b² = c²

36² + b² = 85²

1296 + b² = 7225

b² = 7225 - 1296

b² = 5929

[tex]\sqrt{b^2} =\sqrt{5929}[/tex]

b = 77

Answer:

4.4cm

Step-by-step explanation:

The area of a circle is [tex]\pi r^{2}[/tex], where r is the radius.

Hence the volume of the cylinder would be [tex]\pi r^{2}h[/tex], where r is the radius and h is the height of the cylinder.

We can set up an equation V = [tex]\pi r^{2}h[/tex]

If we plug in the values we know, V=480, h=8, then we get [tex]480=8\pi r^{2}[/tex]

If we divide both sides be 8pi and square root both sides after that, we can find the value of r.

[tex]r = \sqrt{\frac{480}{8\pi } } =4.37019[/tex]

To the nearest tenth, the radius would round up, yielding 4.4cm

Answer:

C) (7.1)^13

Step-by-step explanation:

When you multiply numbers with the same bases but different exponents, the base stays the same, but the exponents get added:

a^x*a^y=a^(x+y)

(7.1)^6*(7.1)^7=(7.1)^(6+7)=(7.1)^13

Therefore, the correct answer is C) (7.1)^13

Answer:

C

Step-by-step explanation:

When multiplying numbers with exponents, you always add the exponents.

7.1^6+7

7.1^13

Hence, C

Answer:

[tex]p =2.5[/tex]

[tex]q = 0.5[/tex]

Step-by-step explanation:

Given

[tex]2x + 3y = 7[/tex]

[tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]

Required

Find p and q

To do this, we make direct comparison between the given expressions.

[tex]2x + 3y = 7[/tex] and [tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]

This implies that:

[tex](p - q)x = 2x[/tex]

[tex](p+q)y = 3y[/tex]

[tex]3(p + q) - 2 = 7[/tex]

So, we have:

[tex]p - q = 2[/tex] --- (1)

[tex]p+q =3[/tex] -- (2)

[tex]3(p + q) - 2 = 7[/tex] --- (3)

If [tex](1)\ and\ (2)[/tex] are true, then [tex](3)\ must[/tex] be true.

So, we only solve [tex](1)\ and\ (2)[/tex]

Add (1) and (2) to eliminate q

[tex]p+p-q+q=2+3[/tex]

[tex]2p=5[/tex]

Solve for p

[tex]p = 5/2[/tex]

[tex]p =2.5[/tex]

Substitute [tex]p =2.5[/tex] in (2)

[tex]p+q =3[/tex]

[tex]q = 3 - p[/tex]

[tex]q = 3 - 2.5[/tex]

[tex]q = 0.5[/tex]

C 28 cm

Step-by-step explanation:

16 ÷ 8 = 2

14 × 2 = 28 cm

it's not A or D

Step-by-step explanation:

math I guessssssss

Answer:

D

Step-by-step explanation:q

If you have a 30 degree reference angle, the side opposite (the side not part of the reference angle) is 1/2 the size of the hypotenuse.

Since the side opposite is 12, the hypotenuse is easily found.

1/2 = opposite / hypotenuse

1/2 = 12 / hypotenuse                     Cross multiply

hypotenuse = 2 * 12

hypotenuse = 24

Now use the Pythagorean Theorem to get the third side.

c = 24

a = 12

b = ?

a^2 + b^2 = c^2

12^2 + b^2 = 24^2

144 + b^2 = 576                                  Subtract 144 from both sides.

b^2 = 576 - 144

b^2 = 432

Now  you have to factor 432 down to its primes

432 = 2 * 2 * 2 * 2 * 3 * 3 * 3

The rule is for every two 2s you take one outside the root sign and throw the other one away. If there are an odd number of factors, leave one of them under the root sign.

sqrt(b^2) = sqrt(432)

b = 4 * 3sqrt(sqrt(3))

b = 12 sqrt(3)

Answer

r = 12*sqrt(3)

t = 24

The answer is D

Answer:

B. 1.32 h : 1 point 3 2 h

Step-by-step explanation:

Year 1 = h hits

Year 2 = 132 % of the hits it received the first year

Number of hits the company's website received the 2nd year = 132% of h

= 132/100 × h

= 1.32 × h

= 1.32h

A. 1 + 0.32h : 1 plus 0 point 3 2 h,

B. 1.32 h : 1 point 3 2 h,

C. ( 1 + 1.32 ) h : open paren 1 plus 1 point 3 2 close paren times h,

D. h + 1.32 h : h plus 1 point 3 2 h,

Answer:

The answer is given below:

Step-by-step explanation:

The computation of the dimension of the pennant is shown below:

As we know that

Area of the triangle = 1 ÷ 2 × base × height

where

x represents the base of the traingle

h represent the height that should be (5x - 10)

Now according to the above formula

420 =  1 ÷ 2 × x × (5x - 10)

840 = x(5x - 10)

840 = 5x^2 - 10x

5x^2 - 10x - 840 = 0

5(x^2 - 2x - 168) = 0

x^2 - 2x - 168 = 0

x^ - 14x + 12x - 168

x (x - 14) + 12(x - 14)

(x + 12) (x - 14)

So, here x = 14

Now height would be

= 5(14) - 10

= 60 inches

Answer:

if this is factoring i wanna say

x= -7

x= 8

but i could be wrong this is a trick 1

Step-by-step explanation:

an equivalent ratio to 6:4 would be 3:2 and an equivalent ratio for 4:3 would be 8:6

hope this helps! :)

The ratios 3:2 and 4:3 are not the same ratio, we can conclude that 6:4 and 4:3 are not equivalent ratios.

A proportion is a statement that two ratios are equal. It compares two ratios and states that they are equivalent.

No, the ratios of 6:4 and 4:3 are not similar. We must reduce each ratio to its simplest form in order to determine whether two ratios are equivalent (by dividing both the numerator and denominator by their greatest common factor).

For 6:4, the greatest common factor is 2, so we can simplify to:

6:4 = 3:2

For 4:3, there are no common factors other than 1, so it is already in its simplest form.

Since 3:2 and 4:3 are not the same ratio, we can conclude that 6:4 and 4:3 are not equivalent ratios.

Answer: 30

Step-by-step explanation:

3(0.3m + 6) + m =75

(0.3 x 3 = 0.9)

(6 x 3 = 18)

0.9m + 18 + m = 75

0.9m + m + 18 = 75

(m=1)

1.9m + 18 = 75

1.9m = 75 - 18

1.9m = 57

m = 57÷ 1.9

m = 30

Answer:

Acute because all angles are less than 90

Step-by-step explanation:

flowers needed to surround the garden = circumference of the garden / space

circumference of a circle = 2nr

n = 3.14

r = radius

The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability

1ft = 12 inches

125 x 3 = 375

2 x 3.14 x 375 = 2355

flowers needed = 2355 / 3 = 785
