Step-by-step explanation:

3. all three equations are in the form of

y = mx + b

where m is the slope and b is the y intercept.

A and X both have a y intercept of 1 so A and C is the answer.

4. A megative slope is included by a negative sign so A and C is the answer.

5. The linear parent function is the identity function which is

y = x

6. Since our points share the same y coordinate, our slope will be a horinzontal line which indicates a slope of zero.

7. The sleepest line has the greatest absolute value slope which is y=-9x.

8. The fattest has the smallest absolute value slope which is y=x+9.

9.The first and second one are parallel because they have the same slope

13.The second one does.

14. 8x+10 is greater slope than 5x.

15. y=5 because it has no y intercept

√3×sinx+cosx=0 tmf nghiệm
Crazy boy [7]

Answer:

x= -30

Step-by-step explanation:

√3×sinx+cosx=0

√3sinx=-cosx

√3sinx/-cosx=1

-sinx/cosx=1/√3

-tanx=1/√3

(tan(180-30))=1/√3

tan(-30)=1/√3

Therefore, x= -30

Let f(x)=2.912345x^2+3.131579x-0.099999
Rudiy27
A.) Integers are positive and negative counting numbers. So, in order to find the integer coefficients, round off the coefficients in the equation to the nearest whole number. The function for g(x) is:

g(x) = 3x²+3x

B.) Substitute x=4 to the two functions.

f(x) = 2.912345x²<span>+3.131579x-0.099999
</span>f(4) = 2.912345(4)²+3.131579(4)-0.099999
f(4) = 59.023837

g(x) = 3x²+3x
g(4) = 3(4)²+3(4)
g(4) = 60

C.) The percentage error is equal to:

Percentage error = |g(4) - f(4)|/f(4)  * 100
Percentage error = |60 - 59.023837|/59.023837  * 100
Percentage error = 1.65%

D.) If x is a large number, for example x=10 or x=20, then g(x) would be an overestimate. This is because the value of x is raised to the power of 2. So, as the x increases, the corresponding function would increase exponentially. Even at x=4, g(x) is already an overestimate. What more for larger values of x? That means that the gap from the true answer f(x) would increase.
