Check whether the sequence is arithmetic. If​ so, find the common difference d. 2​, 7​, 12​, ​17, 22 ... Select the correct choice below​ and, if​ necessary, fill in the answer box within your choice.

Answer:

To find the slope, use the formula rise/run or change in y/change in x

In this case, the slope is 5

To find y-intercept, substitue  values for x and y

Step-by-step explanation:

-3 = 5(2) + b

-3 = 10 + b

-10    -10  

-13 = b

Therefore, b is -13

So here's how the equation looks in slope-intercept form

y = 5x + -13

Answer:

c. 10, -10

Step-by-step explanation:

10x10=100

-10x-10=100

Answer:C

Step-by-step explanation: when doing the square root of 100 it’s 10 but -10 times -10 is also 100 because of double negatives

Answer:

2  to 8  and 8 to -2

Step-by-step explanation:

Solution to these set of inequalities is : 2 < x < 8  

Important Information

x + 7 > 9

x > 9 - 7

x > 2

8x < 16

x < 16/2

x <  8

So, numbers that satisfy the conditions that 2 < x < 8 are solutions to this set of inequalities.

Answer:

8.31

Step-by-step explanation:

By Pythagoras Theorem,

(10)² + x² = (13)²

=> x² = (13)² - (10)²

=> x² = 169 - 100

=> x² = 69

=> x = [tex]\sqrt{69}[/tex]

=> x ≈ 8.31

Answer:

3.225 gram

Step-by-step explanation:

Given that :

Initial weight = 0.06g

Rate of increase, r = 10% = 0.1 per day

Weight gain after 6 weeks

For an exponential model. f(x)

f(x) = a(1 + r)^x

Where ; a = initial amount ; r = growth rate ; x = period

Our model becomes :

f(x) : 0.06(1 + 0.1)^x

f(x) = 0.06(1.1)^x

Number of days in 6 weeks = 6*7 = 42 = x

f(42) : 0.06(1.1)^42

= 3.285 gram

Hence, weight gain after 6 weeks :

(3.285 - 0.06) g = 3.225 gram

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack  to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack

Answer:

an expression equivalent to f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

Step-by-step explanation:

As given ,

f(x) = x³ , g(x) = 9 , h(x) = 2x

Now,

f(2x) = (2x)³ = 2³.x³ = 8x³

⇒f(2x) = 8x³

Now,

[tex]\frac{g(x)}{h(x)} = \frac{9}{2x} = \frac{9}{2}x[/tex]

⇒[tex]3\frac{g(x)}{h(x)} = 3.\frac{9}{2}x = \frac{27}{2}x[/tex]

∴ we get

f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

Answer:

D

Step-by-step explanation:

Here, we want to get the height of the cone

radius = diameter/2

r = 12/2 = 6 m

To get this, we use the formula for the volume

V = 1/3 * pi * r^2 * h

133 = 1/3 * 3.142 * 22/7 *6^2 * h

h = 1.12 m
