Answer: 13
Step-by-step explanation:
I used Pythagorean theorem to solve this problem. As DC and AD is 12 and 5, you would do 12²+5²= c². 12²= 144 and 5²= 25. 144+25= 169. It doesn't end there. Do the square root of 169 ---> √169=13.
Hi, since p=-1, we can replace each p with -1, so -1x2-4x-1+4=6! 6 should be your answer!
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (3,5)
The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex
so
---> axis of symmetry
<u><em>Find the y-intercept</em></u> (value of f(x) when the value of x is equal to zero)
For x=0
The y-intercept is the point (0,14)
<u><em>Find the x-intercept</em></u> (values of x when the value of f(x) is equal to zero)
For y=0
---> has no real solutions
The function has no x-intercepts (The roots of the quadratic equation are complex numbers)
therefore
The graph in the attached figure
Answer:
222cm3
Step-by-step explanation:
9cm × 3cm × 6cm = 162cm
8cm - 3cm = 5cm
5cm × 2cm × 6cm = 60cm3
162cm3 + 60cm3 = 222cm3
Volume = 222cm3
Answer:
5 is the coefficent of y if you simplify and 3 is the constant
Step-by-step explanation:
7y-2y=5y. The coefficient is the number that goes with the variable, or letter, such as y. The constant is the number that does not have any coefficients attached to it.
