Answer:
7.5 miles per hour
Step-by-step explanation:
Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate
To find: speed in miles per hour
Solution:
Distance travelled by Kayla = 
mile
Time = 
hour
To find the speed in miles per hour, use the following formula:
Speed = Distance ÷ Time = 
miles per hour
Answer:
Isosceles triangle.
Step-by-step explanation:
In order to determine the nature of the triangle, we will need to get the sides XY, XZ and YZ using the distance formula;
For XY;
X(-4,2), Y(4.2)
XY = √(2-2)²(4-(-4)²)
XY = √(4+4)²
XY = √8²
XY = 8
For XZ;
X(-4,2), Z(0, - 1)
XZ = √(-1-2)²(0-(-4))²
XZ = √(-3)²+4²
XZ = √9+16
XZ = √25
XZ = 5
For XZ;
Y(4.2), Z(0, - 1)
YZ = √(-1-2)²(0-(4))²
YZ = √(-3)²+(-4)²
YZ = √9+16
YZ = √25
YZ = 5
Since XZ = YZ = 5, this shows that two sides are equal. Hence the triangle is an isosceles triangle.
NB: Isosceles triangle only have two of its sides and angles equal
Answer:
no
Step-by-step explanation:
No, it is not since 2 points have the same x-coordinate and different y-coordinates.
2 is not correct
<span>Use the function below to find f(–4). f(x) = 2x</span>
Hi there!
f(x) = x^3 - 8x^2 + 16x
The multiplicity of a root is the number of times the root appears.
So the answers are
x = 0 and the multiplicity of 1
x = 4 and the multiplicity of 2
I hope this helps!
Good luck!
