Answer:

x=26

y=9

Step-by-step explanation:

(5x-17)+(3x-11)=180

8x-28=180

8x=208

x=26

(2y+5)+90[the right angle]+(3x-11)=180

2y+95+3(26)-11=180

2y+84+78=180

2y+162=180

2y=18

y=9

Consider the function ƒ(x) = –x4 + 9. Determine which of the following is its graph, based on end behavior.

JulsSmile [24]

Answer:

Step-by-step explanation:

If the degree of the polynomial is even (positive) ends of the function will either upwards or downwards on axis.

If the coefficient of the leading term of a polynomial is negative, both the ends of the graph will move downwards.

The given function is,

f(x) = -x⁴ + 9

Degree of the polynomial = 4

Coefficient of the leading term = -1

Therefore, ends of the polynomial will open downwards.

Tasha plans to tile the floor in her room with square tiles that are 1/4 foot long. Will she use more or fewer tiles if she is o

RideAnS [48]

Tasha will use more tiles because 1/4 is smaller fractional portion than 1/3. (1/4=3 ft, 1/3= 4 ft)

Answer:

$V=97.6\ in^3$

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4/2=2\ in$ ---> the radius is half the diameter

$h=8\ in$

substitute

$V=\pi (2)^{2}(8)\\\\V=32\pi\ in^3$

step 2

Find the volume of the cone

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have

$r=2\ in$ ---> the radius is the same that the radius of the cylinder

$h=0.70\ in$

substitute

$V=\frac{1}{3}\pi (2)^{2} (0.70)\\\\V=0.93\pi\ in^3$

step 3

Find the volume of the plastic object

we know that

The volume of the plastic object is equal to the volume of the cylinder minus the volume of the cone

$V=32\pi-0.93\pi=31.07\pi\ in^3$

assume

$\pi=3.1416$

$V=31.07(3.1416)=97.6\ in^3$
