Answer:
x = 28.9
Step-by-step explanation:
tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 48 = [tex]\frac{26}{x}[/tex]
(tan of 48 is 1.11)
⇒ 1.11 = [tex]\frac{26}{x}[/tex]
multiply 26 on both sides
⇒ 1.11 x 26 = [tex]\frac{26}{x}[/tex] x 26
⇒ 28.86 = x
round to the nearest tenth
⇒ 28.86 = 28.9
A particle is moving with the given data. Find the position of the particle. a(t) = t2 − 2t + 9, s(0) = 0, s(1) = 20
Answer:
Position of the particle is 20.
Step-by-step explanation:
Position function is integration of velocity function.
Velocity function is integration of acceleration function.
So, let's integrate the given a(t) to get v(t)
If we integrate v(t) then we get s(t)
It is given the values of s(0) =0 and s(1)=20
So, position of the particle is difference of 20, 0. That's 20-0 =20.

A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.
Answer:
Equation: y = 8x + 56
After 5 minutes, the volume of the water was 96 gallons
Step-by-step explanation:
Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.
Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.
There are already 56 gallons of water in the tank, so b will be 56.
Plug in these values into the equation:
y = 8x + 56
So, the linear equation is y = 8x + 56
Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:
y = 8x + 56
y = 8(5) + 56
y = 40 + 56
y = 96
So, after 5 minutes, the volume of the water was 96 gallons
What does 1/4 equal for a fraction
Answer: 0.25 as a decimal
Answer:
0.25
Step-by-step explanation:
You can think of fractions as smaller increments of money.
2/4=0.5
3/4=0.75
Bob has a dollar bill. He uses 1/4 of it to buy a coupon.
Imagine this happening:
1$
Uses 1/4
So... Let's look at what I've given you.
2/4=0.5
3/4=0.75
Well, let's stretch some things a liiiiitle bit.
Bob has a dollar bill blah blah...
We get to 1/4.
Le's make that 2/4.
2/4 is 0.5
So... By stretching the truth
We can infer that
If we put 1/4 back
(Oh no now the word problem creators are mad at me ;) lol)
Anyways, we can infer that by putting 1/4 back
That since 3/4 is 0.75
Then what's connected to 0.5 and 0.75?
The answer, my friend,
Is 0.25

The total cost C dollars, that a shop charges to print T shirts C = 45 + 7n , is the number of shirts ordered. Coach Dell paid 206 fo order T the track team, How Tshirts did Coach Dell order?
Answer:
i think the answer is 23
Step-by-step explanation:
well the equation says c=45+7n so the total cost is 206 . i subtracted 45 from 206 leaving me with 161 then i divided that by 7 leaving me with 23
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The total cost of n T-shirt is C = 45 + 7n.
The number of T-shirt coach Dell ordered for the team is 23 T-shirts.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Total cost:
C = 45 + 7n
n = number of shirts.
Now,
Dell paid $206.
This means,
206 = 45 + 7n
Subtract 45 on both sides.
206 - 45 = 7n
161 = 7n
Divide both sides by 7.
n = 161/7
n = 23
The number of shirts is 23 if the cost of the paid is $206.
Thus,
The number of T-shirt coach Dell ordered for the team is 23 T-shirts.

Which is an example of a quadratic function whose axis of symmetry is to the right of the y-axis?
A. y=-x2 - 2x + 1
Answer:
a.
Step-by-step explanation:
imagine a graph that you see, the x-axis has to be positive for it to be on the right side of the y-axis so the value of the y axis can be positive or negative and then you substitute for a positive number, in this case, into the x axis and then you would solve for every answer choice to see if it's right or not if it is accurate.

A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Write an equation that represents the situation. Use x to represent the number of roast beef sandwiches. Then determine how many sandwiches the customer buys.
Amount used for payment: 80$
The change received: $19.25
An equation that represents this situation is _____
The customer buys ____ sandwiches
Please help me with these two questions.
Answer:
1. 6.75x or (6.75, 1)
2. He buys 9 sandwiches.
Step-by-step explanation:
For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x
For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.
I hope this helps :)

A new motorcycle has a value of $8000 every year is value decreased by $500 which function can be used to find why the value of motorcycle in X years?
The function for the value of the motorcycle after x years are;
y = 8000 - 500x
y = -500x + 8000
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have given that new motorcycle has a value of $8,000. Every year its value decreases by $500.
Now, we have y = amount of the motorcycle
x = number of years
The function for the value of the motorcycle after x years.
y = 8000 - 500x
y = -500x + 8000
Thus,
y = 8000 - 500x
y = -500x + 8000
