Answer:

(x+7i)(x-7i)

Step-by-step explanation:

Since there is no middle term in the equation, one root must use addition (like a + b) while the other uses subtraction (like a – b) so they cancel one another and the middle term disappears. That would make the third term of the equation negative. However, in this instance, the third term is positive. Therefore, roots with imaginary units must be involved. Thus, (x+7i)(x-7i) is the only solution. This is also true because the complex arithmetic rule results in the following:

(a+bi)(a-bi)=a^2+b^2\\\rightarrow(x+7i)(x-7i)=x^2+7^2\\=x^2+49

37. A company is choosing between two tanks for mixing chemicals Bothhave the same price, so the company plans to choose the one
omeli [17]
Volume of the conical tank = 1/3pi*r^2 * h = 1/3pi * (10/2)^2 * 15 = 125pi cubic feet or 392.7 cubic feet = 392.7 * 7.48 gallons = 2937 gallons.

Volume of the hemispherical tank = 2/3pi * r^3 = 2/3pi * (5.5)^3 = 348.5 cubic feet = 348.5 * 7.8 gallons = 2606 gallons

Hence the conical tank will contain more chemicals

Answer: 1300 cm^3, 850 cm^2

Step-by-step explanation:

With a triangular prism, you need to calculate the surface area of the triangle first and then the length. Here's how to solve for the volume (A):

Triangles is b*h/2, plug in the equation

10*13/2

130/2

65

Now use the length of the rest of the shape, which is 20 cm.

65*20=1300

the volume is 1300 cm^3.

for B, finding the surface area requires you to analyze each individual part of the shape.

Each part colored in represents a different shape:

Red:

10*20=200

Blue:

13*10/2=65

65*2=130 (Two triangles)

Green:

13*20=260

260*2=520 (Two rectangles)

Add them all up together.

200+130+520= 850 cm^2
