Mathematics

Ulleksa [173]3 years ago
3 0

Answer:

Step-by-step explanation:

(f + g)(x) simply means that you are adding together the 2 functions that are written in terms of x.

x^3-x+x^3+2x^2-10

The only like terms we have there are the x-cubed's, so

2x^3+2x^2-x-10=(f+g)(x)

Please help!!!! Can’t figure it out.
OleMash [197]

Answer:

A) x = 12

Step-by-step explanation:

if its a right angle? then the angle in total is 90 degrees,

subtract the 35 from 90 to get 55 degrees,

4x + 7 = 55 solve this

4x = 48

x = 12

the relationship between money earned and hours worked is linear. joe computes the slope between (4, 30) and (12, 90), then comp
julia-pushkina [17]
Slope = rise/run =[y2-y1]/[x2-x1]

1) slope = [90 - 30] / [12 - 4] = 60 / 8 = 15/2

2) slope = [75 - 30] / [10 - 4] = 45 / 6 = 15 / 2

The slopps are equal.

rusak2 [61]

Answer: Step-by-step explanation:

if I am correct.. Katie is gonna be paying $77.76. Meanwhile, Mike and Ryan are paying $38.88

half of 155.52 = 77.76

half of 77.76 = 38.88

$77.76 + $33.88 + $38.88 = $155.52

A triangle has side lengths of 9 in, 13 in, and 20 in. What is the measurement of this triangle’s largest angle?
zvonat [6]
1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :

      i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.

       ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:

       a^{2}=b ^{2}+c ^{2}-2bc(cosA)

2. 

20^{2}=9 ^{2}+13 ^{2}-2*9*13(cosA)

400=81+169-234(cosA)   150=-234(cosA)

cosA=150/-234= -0.641

3. m(A) = Arccos(-0.641)≈130°, 

4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc
