1cm³=1mL
1942cm=x mL
1cm³ 1942cm³
________ = ________
1mL x mL
Cross multiply
1x=1942
divide both sides by 1
x=1942mL
Answer=1942mL
Perimeter of the base = 8 + 5 + 5 = 18 ft
Height = 7 ft
Base area = 1/2 x 8 x 3 = 12 ft²
Surface area = (18)(7) + 2(12) = 150 ft²
--------------------------------------------------
Answer: 150 ft²
--------------------------------------------------
The above answer is according to the worksheet but I will present it in another way for you to understand better.
The figure has 5 sides
-------------------------
Bottom Triangle
-------------------------
Area = 1/2 x base x height
Area = 1/2 x 8 x 3
Area = 12 ft²
-------------------------
Top Triangle
-------------------------
Top Triangle = Bottom Triangle
Top Triangle = 12 ft²
-------------------------
3 Rectangles on the sides
-------------------------
Area of 1st Rectangle = Length x Width
Area of 1st Rectangle = 7 x 5 = 35 ft²
Area of 2nd Rectangle = 7 x 5 = 35 ft²
Area of 3rd Rectangle = 8 x 7 = 56 ft²
Total area of the rectangles = 35 + 35 + 56 = 126 ft²
-------------------------
Total Surface Area
-------------------------
126 + 12 + 12 = 150 ft²
<em>(*Area of the 3 rectangles + top triangle + bottom triangle)
</em>
-------------------------
Answer: 150 ft²

Answer:
C. 0
Step-by-step explanation:
The points of intercection between the graph of a quadratic function of the form are given by the discriminant of the quadratic formula.
Remember that the quadratic formula is:
The discriminant of he quadratic formula is just the thing inside the radical, in other words:
- If the discriminant is negative, the graph of the quadratic function doesn't intercept the x-axis.
- If the discriminant is positive, the graph of the quadratic function intercept the x-axis at 2 points.
- If the discriminant is 0, the graph of the quadratic function intercept the x-axis at 1 point.
We can infer form our quadratic that , , and , so let's replace the values in the discriminant:
Since the discriminant is negative, we can conclude that the graph of the quadratic function doesn't intercept the x-axis at any point.
Dear sir, we know not what you mean.
