Is 5x + 2 a numerical expression?​

Answers

Answer 1

Answer:

Yes

Step-by-step explanation:

Yes, this is a numerical expression because x represents a number.  This number is unknown, so x = 1 --- 5x (1) + 2 is equivalent to 5x + 2.  5x (1) +2 is a numerical expression, SO that means that 5x + 2 is a numerical expression.

Step-by-step explanation:

The formula of the area of the rectangle is A = l × w, where

l is its lengthw is its width

In the rectangle ABCD

∵ AB = 2x cm

l = 2x

∵ AD = x cm

w = x

→ Use the formula of the area above to find its area

∵ A = 2x × x

A = 2x²

∵ The area of the shaded region = 50 cm²

→ When the shaded region removed, then the remaining area is the

   unshaded region

∵ The area of unshaded region = 22 cm²

∵ The area the ABCD = area the shaded region + area unshaded region

∴ A = 50 + 22

A = 72 cm²

→ Equate the two right side of A

∵ 2x² = 72

→ Divide both sides by 2

∴ x² = 36

→ Take √  for both sides

x = 6

Jeremiah's retirement party will cost $16 if he invites 4 guests. What is the maximum number of guests there can be if Jeremiah can afford to spend a total of $20 on his retirement party? Solve using unit rates.

Answers

Answer:

5 guests

Step-by-step explanation:

Jeremiah party will chat $16 if he invites 4 guest

The first step is to calculate how much it will cost to feed one guest

$4 = 16 guests

1 guest= 16/4

1 guest = $4

Therefore if Jeremiah can afford to spend $20 then the maximum number of people that will be present can be calculated as

$4 = 1 guest

$20= 20/4

= 5 guests

Hence the maximum number of guest is 5 guests

The Jackson's dinner cost $125. They left $21.25 as a tip. What was the percentage of the tip? Please explain and help me! THANK YOU!!!

Answers

Answer:

17%

Step-by-step explanation:

to find the percentage of something, you have to fill out the following formula:

x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:

125x = 2125

then you have to divide, to single out x:

the answer is 17

so it is 17%

17%
Divide the tip by the amount dinner was and you get your percentage for the tip

Answers

Answer:

Domain is all real numbers.

Range is -3 to infinity that is y >= -3 (that is y -3)

Increasing from x > -4 ( that is from -4 to +infinity) that is to right of -4

Decreasing from x <-4 (that is -infinity to -4) that is to left of -4

This has a minima at x= -4 with y= -3. We can write as (-4, -3)

Maxima is not there as it is going to infinity

A rock is thrown straight up from the top of a bridge that is 75 ft high with an initial velocity of 32 ft/s. The height of the object can be modeled by the equation s(t) = -16t2 + 32t + 75. Determine the time(s) the ball is lower than the bridge in interval notation.

In two or more complete sentences, explain why (-∞,0) is not included in the solution.

Answers

The ball is lower than the bridge at the interval [2, 3.385] and (-∞,0) contains negative values

How to determine the time the balloon lower than the bridge?

The equation of the function is given as

h(t)= -16t^2 + 32t + 75

The above equation is a quadratic equation

When the balloon is less than the bridge i.e. a height of 75 feet, we have

h(t) < 75

So, we have the following equation and inequality

h(t)= -16t^2 + 32t + 7

h(t) < 75

Next, we plot the equation and inequality on a graph (see attachment)

The equations intersect at

t = 0 and t = 2

Remove when t = 0

t = 2

The ball hits the ground at t = 3.385

So, the interval is [2, 3.385]

Also, (-∞,0) is not included in the solution because time cannot be negative

Write an equation for the nth term of the arithmetic seqeuence. Then find a10 100,110,120,130...​

Answers

The 10th term of this arithmetic sequence 100,110,120,130...​ is 190.

What are arithmetic and geometric sequence?

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, An arithmetic sequence 100,110,120,130...​

First term a₁ = 100, Common difference(d) = 130 - 120 = 120 - 110 = 10.

We know nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)×d.

aₙ = 100 + (n - 1).10.

aₙ= 100 + 10n - 10.

aₙ = 10n + 90

So, the 10th term a₁₀ = 100 + (10 - 1).10 = 100 + 90 = 190.
