State if each triangle is a right triangle: *13 in2 in12 in​

Mathematics
1 answer:
olga_2 [115]3 years ago
7 0

Answer:

It would be a obtuse triangle instead

Step-by-step explanation:

By using pythagorean and theorem (a^2 + b^2 = c^2)

So it would be 13^2___2^2 + 12^2

When you square them, you get 169___4 + 144

144 + 4 = 148, which is less than 169

SO it would be 169>148

So no, not a right triangle

How to solve 2a x a x a x3a + b +4b
kodGreya [7K]

Answer:

6 {a}^{4}  + 5b

Step-by-step explanation:

2a \times  a\times a \times 3 a+ b + 4b \\ 2a \times a = 2 {a}^{2}  \\ 2 {a}^{2}  \times a = 2 {a}^{3}  \\ 2 {a}^{3}  \times 3a = 6 {a}^{4}  \\b +  4b = 5b

Therefore the answer is

6 {a}^{4}  + 5b

cupoosta [38]

Answer:

NPV = $ 17,200,000

Step-by-step explanation:

Total expenditures = $ 11,000,000

Net cash inflow = $ 3,000,000 per year

total duration of cash inflow = 9 years

Thus, total cash inflow = $ 3,000,000 per year × 9 years = $ 27,000,000

salvage value = $ 1.2 million = $ 1,200,000

NPV = Salvage value + total cash flow - Expenditures

on substituting the values, we get

NPV = $ 1,200,000 + $ 27,000,000 - $ 11,000,000

or

NPV = $ 17,200,000

Usimov [2.4K]

Answer:

a) P=0.0225

b) P=0.057375

Step-by-step explanation:

From exercise we have that  15​% of items produced are defective, we conclude that  probabiity:

P=15/100

P=0.15

a)  We calculate the probabiity  that two items are​ defective:

P= 0.15 · 0.15

P=0.0225

b)  We calculate the probabiity  that  two  of  three items are​ defective:

P={3}_C_{2} · 0.85 · 0.15 · 0.15

P=\frac{3!}{2!(3-2)!} · 0.019125

P=3 · 0.019125

P=0.057375
