Answer: D

Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added which means that the difference between consecutive terms is constant and this is referred to as the common difference.

A. would not be an arithmetic sequence because the difference between the terms is not the same. For example, the difference between 2 and 5 is 3 and the difference between 5 and 10 is 5.

B. would not be an arithmetic sequence for the same reason as the first choice. The difference between the terms is not the same.

C. would not be an arithmetic sequence for the same reason as the first and second choices. The difference between the terms is not the same.

D. would be an arithmetic sequence because we add the same number to reach the next term in the sequence.

So to get from -4 to -7, we add -3. to get from -7 to -10, we add -3. To get from -10 to -13, we add -3 and so on.

Wes works at a science lab that conducts experiments on bacteria. The population of the bacteria multiplies at a constant rate,

Dmitry [639]

Answer:

Correct answer: at 2 p.m. the population was 10,000

at 3 p.m. the population was 50,000

Step-by-step explanation:

At 1 p.m. population was 2,000

At 2 p.m. or after first hour, the population of bacteria increases

in this way 2,000 · k

At 3 p.m. or after second hour, the population of bacteria increases

2,000 · k²

At 4 p.m. or after third hour, the population of bacteria increases 2,000 · k³

2,000 · k³ = 250,000 => k³ = 250,000 / 2,000 = 125

k = ∛125 = 5 => k = 5

At 2 p.m. or after first hour, the population of bacteria was 2,000 · 5 = 10,000

At 3 p.m. or after second hour, the population of bacteria was 2,000 · 5² =

= 2,000 · 25 = 50,000

Using a formula estimate the body surface area of a person whose height is 150 cm and who weighs 80 kg.

ladessa [460]

Answer:

B. $1.83\text{ m}^2$

Step-by-step explanation:

We are asked to find the body surface area of a person whose height is 150 cm and who weighs 80 kg.

$\text{Body surface area}( m^2)=\sqrt{\frac{\text{Height (cm)}\times \text{Weight (kg)}}{3600}}$

Substitute the values:

$\text{Body surface area}( m^2)=\sqrt{\frac{150\text{ cm}\times 80\text{(kg)}}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{\frac{12,000}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{3.3333333}$

$\text{Body surface area}( m^2)=1.825741$

$\text{Body surface area}( m^2)=1.83$

Therefore, the body surface area of the person would be 1.83 square meters.

If the angles are represented in degrees, find both angles sin(x+76)=cos(3x+2)

poizon [28]

Step-by-step explanation:

$x + 76 + 3x + 2 = 90$

$4x + 78 = 90$

$4x = 12$

$x = 3$

Angle 1 is 79

Angle 2 is 11.
