Answer:
No. of x-intercepts is equal to the no. of distinct species factors of a polynomial
Since this curve has only one distinct factor i.e (x+7)
The only x-intercepts is -7
(-7,0)
Y intercept would be at (0+7)⁷
Which is (0,7⁷)
Or (0,823543)
Since it's an odd power, branch of the curve for x > 7 would approach positive infinity
Branch for x < 7 would approach negative infinity
No because if you add all of the things she had already bought it would have been 6.09 and if she had bought more the total would’ve been 12.18
$3.25+$1.85+$0.99= 6.09
$6.09- $10.00= $3.91
1. - Since a cube is all the same lengths on all sides you would want to find the area of one of the sides. You would do this by multiplying 3.8 by 3.8.
3.8*3.8=14.44
Since you have six faces on a cube you want to multiply this by 6.
14.44*6=86.64
So your answer for 1. is 86.64 in^2 of glass
3. Same thing as number one. Find the face of one side:
1 1/3*1 1/3 is about 1.7777
Multiply this by the six faces.
1.7777*6 is about 10.66666
So your answer for 3. is about 10.666 (repeating) in^2
4. For this one, you want to follow the surface area formula for a cylinder. Which is - A=2πrh+2πr^2
When you put all your numbers in it would look like this:
2*3.14*2*22+2*3.14*2^2
Once you do that equation you will get 301.44
So that should be your answer 301.44 cm^2
Hope this helps!
