The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?

an = 4 · ( ) n - 1
an = 2 · 4 n - 1
an = 32 · 2 n - 1
an = 4 · 2 n - 1

Answer:

the solution to that is 26.

Answer:

26

Step-by-step explanation:

Substitute x = - 6 into the expression

x² + x - 4

= (- 6)² + (- 6) - 4

= 36 - 6 - 4

= 30 - 4

= 26

Answer:

f = 2 1/4c

Step-by-step explanation:

Number of cups of flour is proportional to the number of cakes

Number of cups of flour = f

Number of cakes = c

Therefore,

f = k * c

Where,

k = constant of proportionality

Number of cups of flour = 22 1/2 cups

Number of cakes = 10 cakes

f = k * c

22 1/2 = k * 10

45/2 = 10k

k = 45/2 ÷ 10

= 45/2 × 1/10

= (45*1) / (2*10)

= 45/20

= 2 5/20

k = 2 1/4

The equation is

f = k * c

f = 2 1/4 * c

f = 2 1/4c

Answer:

Step-by-step explanation:

What is the value of this expression? 6 + (-9) - (-5)

6 + (-9) - (-5)

= 6 - 9 + 5

Following the rules of BODMAS, addition comes first before subtraction

= 6 - 14

= - 8

6 + (-9) - (-5) = -8

Note:

- * - = +

- * + = -

+ * - = -

+ * + = +

The area of the rectangle is 128 square feet.

To find the area of a rectangle, you multiply the length by the width. In this case, the rectangle is 16 feet long and 8 feet wide.

Area = Length * Width

Substituting the given values:

Area = 16 feet * 8 feet

To perform the calculation, multiply the numbers:

Area = 128 square feet

Therefore, the area of the rectangle is 128 square feet.

The area of a rectangle represents the total amount of space enclosed within its boundaries. In this case, the rectangle measures 16 feet in length and 8 feet in width, so the area is calculated as 16 feet multiplied by 8 feet, resulting in 128 square feet.

The concept of area is fundamental in geometry and is used to measure the size of two-dimensional shapes. In the case of a rectangle, the area represents the product of its length and width, as every point within the rectangle contributes to its overall size.

Knowing the area of a rectangle can be useful in various situations. For example, if you want to determine how much flooring material is required to cover a rectangular room, you would need to know the area of the floor.

Answer:

D

Step-by-step explanation:

180-43=137

Answer:

180 - (43 + 56) = 81 (angle 1)

180 - 81 = 99 (angle 2)

180 - 56 = 124 (angle 3)

180 - 43 = 137 (angle 4)

Answer:

At least 16 service technicians

Step-by-step explanation:

Given

[tex]C(t) = -0.0625t^4 + t^3 - 6t^2 + 16t[/tex]

Required

Number of service technician to be online at 12 noon

First, we calculate the value of t

[tex]t = 12\ Noon - 8:00AM[/tex]

[tex]t = 4[/tex]

Substitute [tex]t = 4[/tex] in [tex]C(t) = -0.0625t^4 + t^3 - 6t^2 + 16t[/tex]

[tex]C(4) = -0.0625 * 4^4 + 4^3 - 6 * 4^2 + 16 * 4[/tex]

[tex]C(4) = 16[/tex]

This implies that there are 16 customers online at 12 noon.

If 16 customers are online, then there should be at least 16 service technicians online.

Answer:

C. 74

Step-by-step explanation:

add up all the numbers but not the value so you have 18 numbers. divide that by 2 and get 9. so 74 is between 73 and 78 so it divides the 18 numbers evenly into 9 and 9.

Answer:

If using one pound of pumpkin the baker needs to use 4 pounds of flour mixture

Step-by-step explanation:

step 1: I am going to convert the measurements

into decimals

8/5=1.6

2/5=.4

step 2: I will use cross multiplication to find out how much pumpkin for one pound of flour

1.6=.4

 1=?

1*.4=.4/1.6=.25

step 3:  I will convert .25 into a fraction

.25=1/4

for every 1/4 pound pumpkin, I will use 1 pound of flour

which is why

Answer:

angleQ+angleR is 180degrees because of the properties of isoceles trapezoid. So, if you set equation and solve, you'll get the fact that x is 12, and angleR is 130degrees, and angleQ is 50degrees. According to the properties of isoceles trapezoid, angleQ is the same as angleT. So, angleT is 50degrees

Answer:

Step-by-step explanation:

P(g=1) is equal to

1-P(g=0)-P(g=2)

P(g=0)=(7/12)(6/11)

P(g=2)=(5/12)(4/11) so

P(g=1)=1-(42/132)-(20/132)

P(g=1)=(132-42-20)/132

P(g=1)=70/132

P(g=1)=35/66

Answer:

0 and 4

Step-by-step explanation:

y = x^2 - 4x can be factored as follows:  y = x(x - 4).

We find the zeros by setting this factored form equal to zero and solving for x:

x(x - 4) = 0, or x = 0, or x = 4.

The two zeros of this function are 0 and 4.

The quantity which has magnitude, and direction and follows the law of vector addition is called a vector.

George Washington tosses a baseball with an underlying speed of 20.2 feet each second at a point of 69° degrees with the even.

The initial vertical velocity of the ball is given as,

⇒ 20.2 x sin 69°

⇒ 20.2 x 0.9335

⇒ 18.9 feet per second

The initial horizontal velocity of the ball is given as,

⇒ 20.2 x cos 69°

⇒ 20.2 x 0.3583

⇒ 7.2 feet per second

The initial vertical and horizontal velocity of the ball will be 18.9 feet per second and 7.2 feet per second, respectively. Then the correct option is C.

Answer:

Stefanie bought 10 erasers.

Step-by-step explanation:

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items.

Beind "x" be the number of erasers bought, you can express Stepanie's purchases by the equation:

1.75 + 0.25*x = 4.25

Solving:

0.25*x = 4.25 - 1.75

0.25*x = 2.5

x= 2.5÷ 0.25

x=10

Stefanie bought 10 erasers.
