The graph for |x| + 3 > 3 is attached below.
What is open sentence?It is unknown if a mathematical sentence is true or false since it uses variables, which is known as a "open sentence" in mathematics. On the other hand, a closed sentence is a mathematical statement that is known to be either true or untrue.
Given:
|x| + 3 > 3
|x| > 3- 3
|x| > 0
Now, The open sentence is an absolute inequality, so we start by analyzing the inequality sign > 0 means that, the x-values of the inequality is not less than 0.
So, the shaded area of the graph are: x >0 then right side of the graph is shaded.

a) After 10 years, the amount (future value) in the mutual fund will be $27,679.22.
b) The total amount deposited in the mutual fund is $23,000.
c) The amount of interest earned on the quarterly deposits is $4,679.22.
What is the future value?The future value is the compounded present value of periodic deposits.
The future value is compounded at an interest rate per period.
We can compute the future value using an online finance calculator, which also shows the total deposits and interest earned.
N (# of periods) = 40 quarters (10 years x 4)
I/Y (Interest per year) = 3.7%
PV (Present Value) = $0
PMT (Periodic Payment) = $575
Results:
Future Value (FV) = $27,679.22
Sum of all periodic payments = $23,000 ($575 x 40 quarters)
Total Interest = $4,679.22
Thus, making a quarterly deposit of $575 for 10 years at 3.7% APR will yield a future value of $27,679.22.

A single card is drawn from a standard 52 card deck fund the conditional probability that the card is a spade given that it is a 10
Answers
When the card is a jack, there is a 0.25 probability that you will receive a spade.
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability.
The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
In order to better grasp probability, let's look at a straightforward application. Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.
There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.
According to our question-
P(Spade) = 13/52 = 1/4 P(Jack) = 4/52
= 1/13 P(Spade and Jack)
= (1/4)(1/13) = 1/52 P(Spade/Jack)
= P(Spade and Jack)/P(Jack)
= (1/52)/(1/13) = (1/52)(13/1)
= 13/52 = 1/4 = 0.25
Hence, When the card is a jack, there is a 0.25 probability that you will receive a spade.

Answers
After solving, the maximum height of the ball is 90.25 feet.
In the given question,
A person standing close to the edge on top of a 48-foot building throws a ball vertically upward.
The quadratic function
h(t) = -16t^2+52t + 48 models the ball's height about the ground, h(t) in feet, t seconds after it was thrown.
We have to find the maximum height of the ball.
Height is given that;
h(t) = -16t^2+52t + 48
Now comparing the given equation by the standard equation ax^2+bx+c=0
Here b = 52, a = -16
For maximum height put t= -b/2a
t = -52/2(-16)
t = 52/32
t = 1.625
Maximum height
h(1.625) = -16(1.625)^2+52(1.625) + 48
h(1.625) = -42.25+ 84.5 + 48
h(1.625) = 90.25 feet
The maximum height of the ball is 90.25 feet.

Given that Ethan and his children went into a grocery store and he bought $6 worth of apples and bananas. Each apple costs $0.75 and each banana costs $0.30. He bought a total of 14 apples and bananas altogether.
The number of apples and bananas will be calculated as,
0.75x +0.30y = 6
x + y = 14 or x = 14 - y
0.75(14-y) = 0.30y = 6
10.5-0.75y + 0.30y = 6

trying to find the arc length of the arc for the polar curve r=8cosθ between 0 and π4
Answers
Answer:
Step-by-step explanation:
To find the arc length of the polar curve r = 8cosθ between 0 and π/4, we can use the formula for arc length:
L = ∫a^b √(r^2 + (dr/dθ)^2) dθ
Substituting in the values for r and dθ, we get:
L = ∫0^(π/4) √(8^2cos^2θ + (-8sinθ)^2) dθ
= ∫0^(π/4) √(64cos^2θ + 64sin^2θ) dθ
= ∫0^(π/4) √(64) dθ
= ∫0^(π/4) 8 dθ
= 8(π/4 - 0)
= 8π/4
= 2π
Therefore, the arc length of the polar curve r = 8cosθ between 0 and π/4 is 2π.

Answers
Answer:
Step-by-step explanation: h(t)=-16t2+85
Let h(t)=0 to find when the object will hit the ground
0=-16t2+85
Solve for t=?
We need to get t term on its own
Take 85 from both sides
0-85=-16t2+85-85
-85=-16t2
To get t term on its own
Divide both sides by -16
-85/-16=-16t2/-16
5.3=t2
We have to solve for t squared that means we must take the square root of both sides
