Answer:
For less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.
Step-by-step explanation:
Option 1:
For n calls, the cost is given by:
[tex]C_{1}(n) = 25 + 0.3n[/tex]
Option 2:
The cost is flat of 40, so [tex]C_{2}(n) = 40[/tex]
Which plan is the best option?
Depends on the number of calls, as for a high number, [tex]C_1[/tex] will be higher than [tex]C_2[/tex]. We have to find this number. So
[tex]C_{1}(n) > C_{2}(n)[/tex]
[tex]25 + 0.3n > 40[/tex]
[tex]0.3n > 15[/tex]
[tex]n > \frac{15}{0.3}[/tex]
[tex]n > 50[/tex]
This means that for less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.

Find c. Round to the nearest tenth. Laws of sines
9514 1404 393
Answer:
c ≈ 56.3 cm
Step-by-step explanation:
I find it convenient to turn the given equations upside down. Then you just need to multiply by sin(C) to get the solution.
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (27 cm)sin(102°)/sin(28°)
c ≈ (27 cm)(0.978/0.469)
c ≈ 56.3 cm

What is the volume of a rectangular prisim with the following dimensions?
Length= 4
Width= 3
Height= 10
Answer:
120
Step-by-step explanation:
so volume = l*w*h
= 120
if my answer helps please mark as brainliest.
Answer:
120³
Step-by-step explanation:
Hi!
This is very easy you just need to know the formula for finding the area of a rectangular prism. I attached something to help you with that but I also have an explanation.
The formula to find the area of a rectangular prism is L x W x H,
or in full words Length x Width x Height.
So now lets see what the problem has given us so we can plug things in.
Length = 4
Width = 3
Height = 10
Wow, it gives us all of it!
So now we just have to plug these numbers into the equation and solve.
So :
Length x Width x Height
4 x 3 x 10
Now we solve it :
4 x 3 = 12
And then we take 12 and multiply it by the last 10 in the equation.
12 x 10 = 120
And that is your answer, the volume of the rectangular prism!
Make sure to add a ³ after the 120 like so :
120³
This tiny 3 represents volume in math since the shape is 3D.
And if there are units of measurement involved like feet or inches make sure to put that in there as well like so :
120 feet³
I hope this helps!

Step-by-step explanation:
The given quadrilateral is a parallelogram.
What is a parallelogram?
A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
The proof is as follows;
STATEMENTS REASONS
1) AM = CM and BM = DM Given
2) m ∠ AMB = m ∠ DMC and
m ∠ AMD = m ∠ BMC Definition of Vertical angles
3) Δ AMB ≅ Δ DMC and
Δ AMD ≅ Δ BMC By SAS congruency criterion
4) AB = CD and
BC = AD BY CPCTC
5) ABCD is a parallelogram If both pairs of opposite sides of a
quadrilateral are congruent then it is

x/5 + 20 = 20.1
5x + 20 = 20.1
Answer:
No solution
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
a) The value of x in equation (a) is x = 0.5.
b) The value of x in equation (b) is x = 0.02.
Let's solve the equations for the value of x:
a. X/5 + 20 = 20.1
Step 1: Subtract 20 from both sides to isolate the term with x:
X/5 = 20.1 - 20
Step 2: Simplify the right side:
X/5 = 0.1
Step 3: To solve for x, multiply both sides by 5:
X = 0.1 * 5
X = 0.5
So, the value of x in equation (a) is x = 0.5.
b. 5x + 20 = 20.1
Step 1: Subtract 20 from both sides to isolate the term with x:
5x = 20.1 - 20
Step 2: Simplify the right side:
5x = 0.1
Step 3: To solve for x, divide both sides by 5:
x = 0.1 / 5
x = 0.02
So, the value of x in equation (b) is x = 0.02.

What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
WE are given that angle CAD = 36 degree
So, we know that parallelogram has parallel opposite sides.
Thus according to alternate interior angle we can say that;
angle CAD = angle m<1 = 36
therefore, the measure of angle m<1= 36°

SEE PICTURE
Step-by-step explanation:
Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).
For x + 6 if x < 2,
It becomes 2(x + 6) if x < 2.
We have 2x + 12 if x < 2.
For x² + 4x - 15 if 2 <= x <= 5,
It becomes 2(x² + 4x - 15) if 2 <= x <= 5.
We have 2x² + 8x - 30 if 2 <= x <= 5.
For 5 - x if 5 < x,
It becomes 2(5 - x) if 5 < x.
We have 10 - 2x is 5 < x.
