Answer:
Step-by-step explanation:
To find the length of the pole, use Pythagorean theorem,
4.6m = 4.6*100 = 460 cm
hypotenuse² = base² + altitude²
altitude² = hypotenuse² - base²
=460² - 280²
= 211600 - 78400
= 133200
altitude = √133200 = 364.97 cm
Length of the pole = 364.97 cm
b) Length of stair² = 95² + 364*94²
= 9025 + 133200
= 142225
Length of stair= √14225 = 377.13
Length of stair = 377.13 cm

Answer:
Step-by-step explanation:
Let the age of twins Jasmine and James = x years
For Jasmine,
Karlo told Jasmine to multiply her age by 3 and add 6.
Expression will be → 3x + 6
Then multiply this sum by 2,
We get the expression → 2(3x + 6)
Karlo told James to multiply his age b 2 and add 4,
Expression → 2x + 4
Then multiply this sum by 3,
Expression → 3(2x + 4)
A). Expression for Jasmine → 2(3x + 6)
Expression for James → 3(2x + 4)
When you have a negative power or exponent you move the decimal to the right
when you have a positive exponent or power you move the decimal to the left
