We have that

<span>question 1
Add or subtract. 
4m2 − 10m3 − 3m2 + 20m3
=(4m2-3m2)+(20m3-10m3)
=m2+10m3

the answer is the option
</span><span>B: m2 + 10m3

</span><span>Question 2: 
Subtract. (9a3 + 6a2 − a) − (a3 + 6a − 3)
=(9a3-a3)+(6a2)+(-a-6a)+(-3)
=8a3+6a2-7a-3

the answer is the option
</span><span>B: 8a3 + 6a2 − 7a + 3 

</span><span>Question 3: 
A company distributes its product by train and by truck. The cost of distributing by train can be modeled as −0.06x2 + 35x − 135, and the cost of distributing by truck can be modeled as −0.03x2 + 29x − 165, where x is the number of tons of product distributed. Write a polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck. 


we have that
[</span>the cost of distributing by train]-[the cost of distributing by truck]
=[−0.06x2 + 35x − 135]-[−0.03x2 + 29x − 165]
<span>=(-0.06x2+0.03x2)+(35x-29x)+(-135+165)
=-0.03x2+6x+30

the answer is the option
</span><span>C: −0.03x2 + 6x + 30

Find the value of the cot 10° using your calculator.
Galina-37 [17]
The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.

Find the angle measure. It is not asking for X
MrMuchimi
<h3>Answer:   131 degrees</h3>

Work Shown:

(angle JIW) + (angle WIH) = angle JIH

(2x+8) + (101) = 11x + 10

2x+109 = 11x+10

2x-11x = 10-109

-9x = -99

x = -99/(-9)

x = 11

So,

  • angle JIW = 2x+8 = 2*11+8 = 22+8 = 30 degrees
  • angle WIH = 101 degrees
  • angle JIH = 11x+10 = 11*11+10 = 121+10 = 131 degrees

The smaller angles add to 30+101 = 131 to confirm we have the correct answer.

For more information, check out the angle addition postulate.

In a choose. Cross of choose. Pea plants with round (r) yellow (y) seeds, there will be a choose. Ratio of 9 choose. , 3 choose.
Ludmilka [50]

The pea plants and the yellow seeds are illustrations of genotype ration

The complete statement is: In a monotype cross of heterozygous pea plants with round (R) yellow (Y) seeds, there will be a ratio of 9 round and yellow, 3 round and not yellow, 3 not round and yellow, and 1 not round and not yellow

<h3>How to determine each ratio of the genotype</h3>

To determine the count, we make use of the following representations

  • Round and Yellow -> RRYY
  • Round and not yellow -> RRyy
  • Not round and yellow -> rrYY
  • Not round and not yellow -> rryy

From the complete question, we have:

  • Round and Yellow (RRYY) = 9
  • Round and not yellow (RRyy) = 3
  • Not round and yellow (rrYY) = 3
  • Not round and not yellow (rryy) = 1

Hence, the complete statement is:

9 round and yellow, 3 round and not yellow, 3 not round and yellow, and 1 not round and not yellow
