Given |u| = 10 at ∠135° and |v| = 5 at ∠30°, what expression can be used to find |u + v|?
astraxan [27]

Answer:

B, 10^{2} + 5^{2}- 2(10)(5)cos(75)

Step-by-step explanation:

Using the law of cosines, which is c^{2}=a^{2}+b^{2}-2ab cos(C), you can simply insert all the values.

c=|u+v|

a= r value of u (10)

b= r value of v (5)

To find  C, you simply have to subtract v from u, and then subtract that number from 180 to find the reference angle.

I.E.: ∠135 - ∠30 = ∠105 ↔ 180 - 105 = 75 =  C

so, the completed equation would be 10^{2} + 5^{2}- 2(10)(5)cos(75)

Consider a gene with four alleles a1, a2, a3, and a4. if the cross a1a2 × a3a4 yields two offspring, what is the probability tha
mylen [45]
Possible genetic combinations of offspring are:
<span>
- A1A3
- A2A3
- A1A4
- A2A4
</span>

Therefore, each genotype has a probability of 1/4

The probability of having thesame genotype the second time is 1/4 * 1/4

= 1/16

The probability that both offsprings will have the same genotype is 1/16

Complete the following invoice for upholstery fabric.
Degger [83]

Answer:

a) $49.48

b) $220921.91

Step-by-step explanation:

(a) 4 yd @ $12.37 per yd = 4 x $12.37 = $49.48

(b) 271 yd @ 815.21 per yd = 271 x $815.21 = $220921.91

(c) 20% yd @ $4.95 per yd : Here the nunber of yards are missing. Hence could not be answer . However if number of yards is x . The answer would be

20% of 4.95x

(20%=0.20)

0.20 × 4.95x

Help, question is below :)))
qaws [65]

Answer:

$43 million

Step-by-step explanation:

<h3>Step 1. Turn the sentence into an equation (total = T)</h3>

15.4 million = 0.36 (T)

<h3>Step 2. Solve for T </h3>

15,400,000 / 0.36 = T

42,777,777.78 = T

$42.8 million ≈ $43 million (rounded)

The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!

Hope this helps :)
