b. 1.05×10−14

c. 1.05×10−13

d. 1.05×1015

option B

Step-by-step explanation:

Multiply.

To multiply it we apply exponential property

First we multiply the number 3.5  and 3

3.5 times 3 is 10.5

Now we apply exponential property to multiply the exponents

To get the expression in scientific notation we move the decimal point 1 units to the left

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
