XCIX = LV _ XXXIII
XI
i need to know what signs go where is it "+ +" or "- +"
or "+ -" or "- +" ???
Answer:
The sign that go in the expression is - "+ +"
Step-by-step explanation:
Given - XCIX = LV _ XXXIII _ XI
To find - i need to know what signs go where is it "+ +" or "- +" or "+ -" or "- +" ???
Proof -
We know that from the table that,
XCIX = 99
LV = 55
XXXIII = 33
XI = 11
So,
The equation becomes
99 = 55 _ 33 _ 11
Now,
If we put + + then the equation becomes
99 = 55 + 33 + 11
⇒99 = 99
It satisfies.
Now,
If we put - + then the equation becomes
99 = 55 - 33 + 11
⇒99 = 33
It does not satisfies.
Now,
If we put + - then the equation becomes
99 = 55 + 33 - 11
⇒99 = 77
It does not satisfies.
So,
The sign that go in the expression is - "+ +"
The correct mathematical signs are "++" to have XCIX = LV + XXXIII + XI
This is the application of Roman Numerals.
Given the expression XCIX = LV _ XXXIII _XI
We need to know which of the signs will fit in the space provided in the equation.
First, we need to convert the roman numeral to roman figures as shown:
XCIX = 99
LV = 55
XXXIII = 33
XI = 11
Taking the sum of the right-hand side of the equation;
55 + 33 + 11 = 99
This shows that the correct mathematical signs are "++" to have
XCIX = LV + XXXIII + XI

Complete the square
to find the vertex
of this parabola.

х
- 16 Y-4 x-12=0
Answer:
Vertex coordinates; (h,k) = (2, -1)
Step-by-step explanation:
Vertex form of a parabola is;
y = a(x - h)² + k
Now, we are given;
x² - 16y - 4x - 12 = 0
Rearranging, we have;
x² - 4x = 16y + 12
Let's complete the square on the left hand side;
First add square of half of the coefficient of x to both sides;
x² - 4x + (-½ × 4)² = 16y + 12 + (-½ × 4)²
x² - 4x + 4 = 16y + 12 + 4
LHS can be expressed as;
(x - 2)² = 16y + 16
16y = (x - 2)² - 16
Divide both sides by 16 to get;
y = (1/16)(x - 2)² - 1
Comparing this with y = a(x - h)² + k, we have;
a = 1/16
h = 2
k = -1
(h,k) = (2, -1)
Which is an equation of the line through (-1, –4) and parallel to the line 3x + y = 5?
Answer:
3x + y = -7
Step-by-step explanation:
The desired equation has exactly the same form as does the given 3x + y = 5 except that we must replace the 5 with a 'C' and find the value of 'C.'
Write out 3x + y = 5. Replace the x with -1, the y with -4. Calculate C:
3(-1) + -4 = C, or C = -7
the desired equation is 3x + y = -7

The rectangular pyramid below has a volume of 200 m3. What is the height of the rectangular pyramid in meters? If the base is 6 by 5 meters
Answer:
6.67meters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid = Length × Width × Height
From the question
Volume = 200m³
Base of the pyramid = Length × Width = 6m by 5m = 6m × 5m
To find the height of the pyramid = Volume/Length × Width
Height = 200m³/ 6m × 5m
Height = 6.67m
Height of the rectangular pyramid in meters = 6.67 m
Find the volume of the cylinder.

A rectangular prism shaped produce drawer in a refrigerator is 8 inches tall. The perimeter of the bottom of the drawer is 48 inches. The length of the bottom of the drawer is 4 inches longer than the width
Question: A rectangular prism shaped produce drawer in a refrigerator is 8 inches tall. The perimeter of the bottom of the drawer is 48 inches. The length of the bottom of the drawer is 4 inches longer than the width. Find the volume of rectangular prism shape.
Answer:
1120 cubic inch
Step-by-step explanation:
Applying
V = Ah................... Equation 1
Where v = volume, A = Area of the base, h = height.
Note: The prism has a rectangular base,
Therefore,
A = l×w
A = lw................... Equation 2
Where l = lenght of the rectangle, w = width of the rectangle.
Substitute Equation 2 into equation 1
V = lwh................. Equation 3
Also
P = 2(l+w).................. Equation 4
From the question,
l = w+4 (the length of the bottom of the drawer is 4 inches longer than the width), P = 48 inches.
Substitute these values into equation 4
48 = 2(w+4+w)
2(w+4+w) = 48
(w+4+w) = 48/2
(w+4+w) = 24
2w+4 = 24
2w = 24-4
2w = 20
w = 20/2
w = 10 inches, l = 10+4 = 14 inches.
Also given: h = 8 inches.
Substitute these values into equation 3
V = 10×14×8
V = 1120 cubic inch

One member from a book club is randomly selected. There is a 40% chance the member is male, and there is a 15% chance that the member is male and finished reading the last book. What is the probability that the member did not finish reading the last book, given that the member is male?
Answer:
18%
Step-by-step explanation:
Given that
40% would be the chances the member is male
And, 15% chance that the member is male and finished the reading of the last book
We need to find out the probability
Let us assume the probability of reading the last book be P(R)
The probability that the member is a male, P(M) = 0.4
The probability that the member is male and finished reading the last book, P(M ∩ R) = 0.15
Now
P(M ∩ not R) = 0.40 - 0.15
= 0.25
P(not R | M) = P(M ∩ not R) ÷ P(M)
P(not R | M) = 0.18
= 18%
5. Anthony owns a business that sells parts for electronic game systems. The profit for his business can be
modeled by the equation P = -0.2x2 + 10x – 25, where x is the quantity sold, in thousands, and P is the
profit in thousands
a) What is the maximum profit Anthony will receive
b) How many parts would he need to sell to receive the maximum profit?
Solution given:
p(x)=0
-0.2x2 + 10x – 25=0
-0.2(x²-50x+125)=0
x²-2.25.x+25²=25²-125
(x-25)²=500
x-25=[tex] \sqrt{500} [/tex]
x-25=±10√5
taking positive
x=22.3606+25
x=47.3606
taking negative
x= -22.3606+25
x=2.639
so
maximum profit Anthony will receive :47.3606*1000= 47360600(approach)
now
47360 .6 or 2639 parts he would need to sell to receive the maximum profit

Answer:
A is false (Y is far left of 0, so it is a negative. H is close to 0 so it is positive. Y is farther from zero, so it is bigger. For example, Y could be -7, and H could be 3. The sum of -7 and 3, would be -5.
B is false (E is on the left of 0 so it is negative. Y is on the left of zero so it is also negative. Negative divided by a negative is a positive )
C is false (H is positive and E is negative. Positive times a negative equals a negative.)
D is true (A is close to zero, so it is a small positive number. H is farther from zero, so it is a larger positive number. For example, A can be 2 and H can be 5. So, 3 - 5 would equal a negative.)
