Answer:
f(5) = 2
Step-by-step explanation:
it says to use the function (-x+3) for when x is bigger than 2
f(x) = (-x) + 3 replace x with 5
f(5) = (-5) + 3 and f(5) = 2
Answer:
[tex]f(5)=-2[/tex]
Step-by-step explanation:
In piecewise functions, we need to find the applicable equation to use based on our value of [tex]x[/tex]. [tex]f(5)[/tex] denotes [tex]x[/tex] as 5. Since [tex]5>2[/tex], we will use the equation that corresponds to [tex]x>2[/tex], which is [tex]-x+3[/tex].
Substituting [tex]x=5[/tex], we have:
[tex]x=-(5)+3,\\x=-5+3,\\x=\boxed{-2}[/tex]
What is the value of x? what is the measure of
Answer:
x = 21, ∠ ABE = 55°
Step-by-step explanation:
∠ ABD is right and
∠ ABE + ∠ DBE = ∠ ABD , that is
3x - 8 + x + 14 = 90
4x + 6 = 90 ( subtract 6 from both sides )
4x = 84 ( divide both sides by 4 )
x = 21
Then
∠ ABE = 3x - 8 = 3(21) - 8 = 63 - 8 = 55°

Answer:
Step-by-step explanation:
to find ∠QPS we need the arc SQ and RS we will take 1/2(RS-QS) = QPS
find QS :
360 = RS + RQ + QS
360 = 150 + 110 + QS
100 = QS
now plug into formula above
∠QPS = 1/2(150-100)
∠QPS = 1/2(50)
∠QPS = 25°
Frank was skiing down big bear mountain. He finished 22% of his skiing in the morning. Then he still had 23.4 miles left. How many miles did he ski in the morning?
Answer: 6.6 miles
Step-by-step explanation:
Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.
The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:
78% of x = 23.4
0.78 × x = 23.4
0.78x = 23.4
x = 23.4 / 0.78
x = 30 miles
Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:
= 30 - 23.4
= 6.6 miles

What is the length of the base of a triangle with a height of 7 and and area of 7?
Answer:
base = 2
Step-by-step explanation:
area = 1/2 base * height
7 = 1/2b * 7
7 = 7b/2
cross multiply
14 = 7b
divide both sides by 7
b = 2
Answer:
2
Step-by-step explanation:
So the formula for area of a right triangle is A=B*L*1/2
Variables to remember:
H=height
B=base
A=area
We know that 7=7*B* 1/2. Since they say area is 7, height is 7.
So, we know that L has to equal 1 to make 7*B=7
However, we must remember that this is *1/2. So to make area=7, we must get 14. To get 14, we must have 7*2*1/2, which would equal 14*1/2, equaling 7.
So the answer for B is:
2

Answer:
D. 2%
Step-by-step explanation:
The growth rate can be found by looking at the growth factor of the exponential function.
f(x) = (initial value) × (growth factor)^x
The growth rate is related by ...
growth factor = growth rate + 1
This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.
__
We can write the function g(x) describing the table as ...
g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))
So, this could be ...
g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x
where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor
This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.
__
Then the difference between the growth rates of the two functions is ...
4% - 2% = 2% . . . . . matches choice D

1. An account is opened with a balance of $2800
earning 4.25% simple interest. What will be the
balance in the account in 30 years?
Answer:
The simple interest in the account will be $3570 and the total amount including principle and simple Interest will be $6370Step-by-step explanation:
firstly ,
Given That
principal(p)=$2800
Rate(R)=4.25%
Time(T)=30 years
now , we have from formula
simple interest (S.I)= P × T ×R / 100
= (2800×30×4.25) / 100
= $3570
Therefore , Simple Interest in 30 years will be $3570
now , we know
Amount(A) = Principal (P) + Interest (I)
= $2800 + $3570
= $ 6370
Therefore the simple interest in 30 years will be $3570 and the total amount in the bank will be $6370 .

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 9cm, and the base has a radius of 4cm. How much water is needed to fill 150 cups? Use 3.14 for π, and do not round your answer.
Answer:
22608cm³
Step-by-step explanation:
Step 1
We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.
Cup is shaped as a cone
The volume of a cone = πr²h/3
Where
r = radius = 4cm
h = height = 9cm
π = 3.14
Hence,
Volume of the cone (cup) =
3.14 × 4² × 9/3
= 150.72 cm³
Step 1
How much water is needed to fill 150 cups?
1 cup = 150.72 cm³ of water
150 cups = x
Cross Multiply
x = 150 × 150.72 cm³
x = 22608 cm³ of water
Therefore, 22608cm³ of water is needed to fill 150 cups

What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.
Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.
Let x be the length of the radius. Then we have
x² = 6² - 5²
x² = 36 - 25
x² = 11
x = √11
x = 3.316
x ≅ 3.3

dimensions of the classroom are 30 units by
30 units. Each desk is two units wide by
three units long. How much space will be
leftover after all the desks are in the room?
Answer:
750 units.
