Answer:
I'm going to use the Pythagoras theorem
1. hypotenus²= base²+height²
h²=80²+18²
h²=6400+324
√h²=√6724
hypotenuse= 82
2. 53²=45²+h²
2809=2025+h²
2809-2025=h²
784=h²
√784=√h²
h=28
3. 40²=b²+24²
1600=b²+576
1600-576=b²
√1024=√b²
b= 32
Answer: -26=p
Explanation: The slope formula is m=(y2-y1)/(x2-x1).
Thus, we have 6=(2-p)/(-10-(-6)).
Combining the xs gives us 6=(2-p)/-4.
Multiplying both sides by -4 leaves us with -24=2-p.
We do -24-2 to isolate p and find that p=-26.
Hello!
The discriminant of quadratic functions is: b² - 4ac. Since the equation is in standard form, which is Ax² + Bx + C = 0 , we can substitute those values into our discriminant and simplify.
The value of the discriminant will tell us how many solutions there are to the given quadratic equation.
A positive discriminant will have two real solutions.
A discriminant of zero will have one real solution.
A negative discriminant will no real solutions.
1. Substitute, a = 16, b = 8, c = 1.
8² - 4(16)(1)
64 - 4(16)(1)
64 - 64(1)
64 - 64
0
Since the discriminant is zero, the answer is choice A, double root, because since it is raised to the power of 2, it must has two roots, but in this case, both of the roots the same x-values.
Double time pay.....basically, this means double his regular pay
2(9.86) = 19.72 per hr for overtime pay
at 13 hrs...
19.72 (13) = 256.36 total overtime pay
