Answer:
1. x=4
2. x=6
Step-by-step explanation:
I've attached the graphs here:
Clearly, the solution for first one is(Reminder: the solution is the x-intercepts, when y is zero):
x=4
And the second is:
x=6
Hope this helps!
Mark brainliest if you think I helped! Would really appreciate!
Answer:
Step-by-step explanation:
f(x)=x^2 represents a parabola with vertex at (0, 0), that opens up.
If we translate this graph h units to the right, then g(x) will be:
g(x) = (x - h)^2.
If we translate the graph of f(x)=x^2 k units up, then g(x) will be:
f(x)=x^2 + k
Next time, please indicate whether you are shifting the original graph to the right or to the left, and/or up or down.
Answer:
Given :An Internet survey was e-mailed to 6977 subjects randomly selected from an online group involved with ears. There were 1337 surveys returned.
To Find : Use a 0.01 significance level to test the claim that the return rate is less than 20%.
Solution:
n = 6977
x = 1337
We will use one sample proportion test



We are given that the claim is the return rate is less than 20%.

Formula of test statistic = 
= 
= 
Refer the z table
P(z<-1.85)=0.0332
Significance level = 0.01=α
Since p value > α
So, we accept the null hypothesis .
So,the claim that the return rate is less than 20% is false.

ANSWER:
We know that angle fromed by same arc are congruent. so
∠ACB ~ ∠ADB
∠CAD ~ ∠CBD
Therefore, ΔCAF ~ ΔDBF by AA similarity. So, By CPCT
arcAC = arcBD.
