Answer:
26.2 degrees
Step-by-step explanation:
Yuo would subtract the angle value known from the total value. So 68.2 - 42 = 26.2.
Answer:
8y^2 - 10y + 3
Step-by-step explanation:
(2y – 1)(4y – 3)
Using FOIL
=(2y)(4y) -(2y)(3) - (1)(4y) - (1)(-3)
= 8y^2 - 6y - 4y + 3
= 8y^2 - 10y + 3
2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
It is more effective if I explain using examples. So, for multiplication, you just have to multiply the magnitude, then add the exponents of the base 10. For example, when you multiply 5.2×10³ and 1.6×10², the solution would be:
(5.2)(1.6)(10³⁺²) = 8.32×10⁵
Now, for division, you will have to divide the magnitudes, and subtract the exponents by numerator minus denominator. The solution is as follows:
(5.2/1.6)(10³⁻²) = 3.25×10¹
