Answer:
Touches at -3 and crosses at 3.5
Step-by-step explanation:
f(x)=(2x-7)^7 (x+3)^4 is given
To find x intercepts:
for x intercepts the value of f(x) =0
Hence f(x)=(2x-7)^7 (x+3)^4=0
Solving we get
2x-7 =0 or x+3 =0
x = 3.5 or x=-3
Thus we find the zeroes of the polynomial of f(x) are 3.5 and -3.
3.5 has a multiplicity of 7 and -3 a multiplicity of 4
Since 7 is odd, i.e. 3.5 has a multiplicity of odd number, hence f(x) crosses x axis at x 3.5
Since -3 has a multiplicity of an even number 4, we find that the curve touches x axis at the point -3.
Answer:
pie is known as 3.14 the radius is 19 the r^2 is 361
Step-by-step explanation:
pie is mathmatticly know as just 3.14 the radius is half the diameter and r^2 multiplys the radius by itself like 19 times 19
Solution :
It is given that a psychologist wants to determine the difficulty of the task influences on the estimate of how long people spend working on it.
Now we have to describe a experiment by using a completely randomized design and learn the effect of the difficulty on the estimated time is by randomly assigning 15 students to a Group 1 of easy mazes and other 15 students to the second group 2 of hard mazes. And then we compare the time estimates of the two groups.
I believe the answer is 21
It's called the "dividend". A dividend is a number to be divided by another number. The 3 is the divisor, a number by which another number is to be divided.
