?= 35.66º
Step-by-step explanation:
26/32=0.8125
cos 35.66º=0.8125
Answer:
? = 36 degrees
Step-by-step explanation:
Use trigonometry!
since we know the adjacent and hypotenuse sides, use cos.
cos(?) = adjacent/hypotenuse = 26/32
? = arccos(26/32)
? = 35.659
Rounding it up, we get.
? = 36 degrees

A 5.0 µC point charge is moved within an electric field and has an electric potential energy change of 10.0 J. What is the electric potential difference before and after the charge was moved? Show work. (µC = 1.0 × 10–6)
Answer:
Step-by-step explanation:
so
V = energy / q
The potential difference * charge = potential energy change of charge
delta V = 10J/(5*10^-6) = 2*10^6 volts

A.33
B.44
C.55
D.66
Answer:
55
Step-by-step explanation:
There are 11 units used on the paper. If each unit is 5cm, that means you can do 11*5 and get 55 cm.
Answer:
55
Step-by-step explanation:
1 unit = 5cm
we need to find out how much 11 units are so,
we multiply both sides: 1 unit *11 = 5cm*11, 11 units = 55 cm

The hypotenuse of the right triangle is 29 units.
The ratios are as follows:
sin x = 20 / 29
cos y = 20 / 29
What is a right angle triangle?Right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios. The sides can also be solved using Pythagoras theorem.
The hypotenuse side is the longest side of a right angle triangle.
Therefore,
c² = a² + b²
c = √20² + 21²
c = √400 + 441
c = √841
c = 29
hypotenuse = 29 units
sin x = opposite / hypotenuse = 20 / 29
cos y = adjacent/ hypotenuse = 20 / 29

Which answer uses the distributive property to simplify the following? 3 × (5 + 8) A. (3 × 5) + (3 × 8) B. (3 × 5) × (3 × 8) C. 3 + 5 + 8
Answer:
A. (3 x 5) + (3 x 8)
Step-by-step explanation:
The Distributive property distributes the common factor that the numbers in the parenthesis are multiplied with.
Ex. A(B + C) will equal (A x B) + (A x C).
3 x (5 + 8) will equal (3 x 5) + (3 x 8).
