POLS HELP ME NOWWWW I DONT UNDERSTAND IT
Leni [432]

Answer:

B

Step-by-step explanation:

using the equation 'y = 12x', if you plug in zero for 'x' you get zero for 'y'; the only graph that has the point (0, 0) is (b)

also, the x-axis represents time so, as time increases, so does the number of calories burned (which is measured on the y-axis) -- not staying flat or decreasing

A triangle has side lengths of 9 in, 13 in, and 20 in. What is the measurement of this triangle's largest angle?
Rama09 [41]

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

Find the volume of the composite solid below. If needed,round to the nearest hundredth. Use 3.14
ZanzabumX [31]

Answer:

429.42 cm

Step-by-step explanation:

<u>Volume of a rectangle prism:</u>

V = whl

V = (5)(12)(7)

V = 420

<u>Volume of a cylinder:</u>

V = πr²h

V = (3.14)(1²)(3)

V = (3.14)(1)(3)

V = 9.42

<u>Combined:</u>

420 + 9.42

429.42
