Answer:
Kathleen, a professional golfer, had an average score last season
of 80 points. This season, her average score has been 72 points.
What is the percent of decrease in Kathleen's average score
Answer:
49cm^2
Step-by-step explanation:
The perimeter is just a continuous line which forms the boundaries of a geometric figure.
The perimeter is just all the sides added up.
12cm+10cm+10cm+8cm+6cm+3cm = 49cm^2
Answer:
D. -3.0 < x < 7.5
Step-by-step explanation:
Given the side lengths of a triangle: 6.5 units, 3.5 units, and 2.5 + x units
For the triangle to exist:
- A side length cannot be negative
- A side length cannot be zero
Therefore, the third side length
x+2.5>0
x>-2.5
x must be greater than -2.5 and less than or equal to 6.5 units.
The correct option is D which satisfies this condition.
D. -3.0 < x < 7.5
Answer:
Step-by-step explanation:
![{ \tt{\int\limits^2_1 {x^{2}-8x+8 } \, dx}} \\ \\ = { \tt{[ \frac{ {x}^{3} }{3} - 4 {x}^{2} + 8x ] {}^{2} _{1}}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%5Cint%5Climits%5E2_1%20%7Bx%5E%7B2%7D-8x%2B8%20%7D%20%5C%2C%20dx%7D%7D%20%5C%5C%20%20%5C%5C%20%3D%20%20%7B%20%5Ctt%7B%5B%20%5Cfrac%7B%20%7Bx%7D%5E%7B3%7D%20%7D%7B3%7D%20%20-%204%20%7Bx%7D%5E%7B2%7D%20%20%2B%208x%20%5D%20%7B%7D%5E%7B2%7D%20_%7B1%7D%7D%7D)
Substitute x with the limits:
Answer:
x+y=0
Step-by-step explanation:
slope m of given equations is
(-5+1)÷(3+1)
=-1
then the equations of this line is
y-(-1)=m(x-1)
or, y+1=-1(x-1)
or, y+1= -x+1
or, x+y=0
x+y=0 is required equation of line.
