Step-by-step explanation:

Answer:

first term is 8 and common difference d is -4

Step-by-step explanation:

nth term of an arithmetic sequence is: aₙ=12-4n

First term is putting n=1:

aₙ=12-4n

a₁=12-4(1)

a₁=12-4

a₁=8

So, first term a₁= 8

Now finding second term to find common difference

Second term is: n=2

aₙ=12-4n

a₂=12-4(2)

a₂=12-8

a₂=4

So, second term is: 4

The common difference is: a₂-a₁= 4-8 = -4

So, first term is 8 and common difference d is -4 if nth term is 12-4n

Answer:

It'll take 12 years

Step-by-step explanation:

Given

Type A:

[tex]Initial\ Height = 10ft[/tex]

[tex]Growth = 19in[/tex]

Type B:

[tex]Initial\ Height = 4ft[/tex]

[tex]Growth = 25in[/tex]

Required

Determine the years they'll reach the same height

First, convert feet to inches in both measurements (this is done by multiplying measurement by 12):

Type A:

[tex]Initial\ Height = 10ft[/tex]

[tex]Initial\ Height = 10 * 12in[/tex]

[tex]Initial\ Height = 120in[/tex]

Type B:

[tex]Initial\ Height = 4ft[/tex]

[tex]Initial\ Height = 4 * 12in[/tex]

[tex]Initial\ Height = 48in[/tex]

The height at any year from both trees is calculated using

[tex]Height = Iniital\ Height + Growth * x[/tex]

Where x represents the year;

For Type A:

[tex]Height = 120+ 19 * x[/tex]

[tex]Height = 120+ 19x[/tex]

For Type B:

[tex]Height = 48+ 25 * x[/tex]

[tex]Height = 48+ 25x[/tex]

To get when their height will be equal, we simply equate both expressions:

[tex]48+ 25x = 120 + 19x[/tex]

Collect Like Terms

[tex]25x - 19x= 120 - 48[/tex]

[tex]6x= 72[/tex]

Solve for x

[tex]x = 72/6[/tex]

[tex]x = 12[/tex]

Hence, It'll take 12 years

Answer:

for 7-12 plot the points on a graph. its the rise/run. from the point farthest to the left, go down or up until you are on the same horizontal line. however many units you moved is the first number. (_/?). then from that point, go to the right until to actually land on the point. however many units you used is your second number. The slope will be in a fraction, and sometimes you can turn it into a whole number.

Answer:

25-2

----------  less than 8

   3

Step-by-step explanation:

25 - 2 = 23

23/3 = 7.666...

the answer to the inequality will be less than 8 since 7.6666... < 8

x-intercept: (7,0), y-intercept: (0,-3). Therefore, the correct answer is option B.

The given equation of a line is 3x-7y=21.

The x-intercept is the value of the x-coordinate of a point where the value of y-coordinate is equal to zero.

When y=0, we get

3x-7(0)=21

3x=21

x=7

So, the x-intercept is (7, 0)

The y-intercept is the value of the y-coordinate of a point where the value of x-coordinate is equal to zero.

When x=0, we get

3(0)-7y=21

0-7y=21

y=-3

So, the y-intercept is (0, -3)

Therefore, the correct answer is option B.

Step-by-step explanation:

The Greatest Common Factor (GCF) for 14 and 56, notation CGF(14,56), is 14.

Explanation:

The factors of 14 are 1,2,7,14;

The factors of 56 are 1,2,4,7,8,14,28,56.

So, as we can see, the Greatest Common Factor or Divisor is 14, because it is the greatest number that divides evenly into all of them.

Answer:

The cage will cover an area of 805 ft^2 on the Ocean floor

Step-by-step explanation:

To calculate the amount of space the cage has on the Ocean floor, we calculate the area of the base of the cylinder

Mathematically, that will be pi * d^2/4

= 22/7 * (32 * 32)/4

= 22/7 * 256 = 804.5714285714286

The cage will cover an area of 805 ft^2 on the ocean floor

Answer:

we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Step-by-step explanation:

Given the expression

[tex]4 < -2x + 3 < 9[/tex]

SECOND STEP

subtract 3 from the right-hand side as well as on the left-hand side

[tex]4-3 <-2x+3-3<9-3[/tex]

SOLVING THE REMAINING COMPLETE COMPRESSION

[tex]1 < -2x < 6[/tex]

Divide all parts by -2

so the expression becomes

[tex]\frac{1}{-2}\:<\:\frac{-2x}{-2}\:<\:\frac{6}{-2}[/tex]

[tex]\frac{1}{-2}\:>x\:<\:-3[/tex]

Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.

Answer:

Price Per Item

Step-by-step explanation:

Given:

The value is [tex]\log_90.877[/tex].

To find:

The logarithm to four decimal places using the change of base rule.

Solution:

We have,

[tex]\log_90.877[/tex]

Using the change of base rule, we get

[tex]\log_90.877=\dfrac{\log_{10}0.877}{\log_{10}9}[/tex]      [tex][\because \log_yx=\dfrac{\log_ax}{\log_ay}][/tex]

[tex]\log_90.877=\dfrac{-0.057000}{0.9542425}[/tex]

[tex]\log_90.877=-0.0597332439081[/tex]

Round the value to the four decimal places.

[tex]\log_90.877\approx -0.0597[/tex]

Therefore, the required value is -0.0597.

By the Pythagorean Theorem, the lengths of the sides of a triangle satisfy [tex]a^2+b^2=c^2[/tex] if the triangle is a right triangle (in which case the angle between sides a and b is the right angle).

Answer:

[tex]\dfrac{4}{15} \approx \bold{0.267}[/tex]

Step-by-step explanation:

Given that:

Number of lemon - lime flavored bottles = 8

Number of orange flavored bottles = 7

Bottles are picked one by one.

First for the friend and then for the person himself.

To find:

The probability that both the bottles drawn are of lemon-lime flavor.

Solution:

Total number of bottles available in the cooler = 8 + 7 = 15

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

[tex]P(First\ lemon-lime) = \dfrac{8}{15}[/tex]

Now, lemon - lime flavored bottles left = 7

Total number of bottles left = 14

[tex]P(Second\ lemon-lime)=\dfrac{7}{14}[/tex]

Required probability:

[tex]P(Both\ lemon - lime) = \dfrac{8}{15}\times \dfrac{7}{14}\\\Rightarrow P(Both\ lemon - lime) = \dfrac{4}{15} \approx \bold{0.267}[/tex]
