<em>Answer: When dividing by 10, 100, 1000 and so on, move the decimal point to the left as many places as there are 0s. So when dividing by 10, move the decimal point one place, by 100 two places, by 1000 three places and so on.</em>

pentagon [3]

Answer:

Brian has $776 more account in his account than Chris.

Step-by-step explanation:

Compound interest Formula:

A=P(1+r)^t

I= A-P

A= Amount after t years

P= Initial amount

r= Rate of interest

t= Time in year

Given that,

Brian invests $10,000 in an account earning 4% interest, compounded annually for 10 years.

Here P = $10,000 , r= 4%=0.04, t=10 years

The amount in his account after 10 years is

A=10000(1+0.04)^{10}

   =$14802.44

  ≈$14802

Five years after Brian's investment,Chris invests $10,000 in an account earning 7% interest, compounded annually for 5 years.

Here P = $10,000 , r= 7%=0.07, t=5 years

The amount in his account after 5 years is

A=10000(1+0.07)^{5}

   =$14025.51

  ≈$14026

From the it is cleared that Brian has $(14802-14026)=$776 more account in his account than Chris.

Line segments AB and BC are tangents to Circle P. What is the value of x?
QveST [7]

Answer:

c. 107°

Step-by-step explanation:

In the figure attached, Circle P, segments AB and BC, and angle x are shown.

From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:

x + 73° = 180°

x = 180° - 73°

x = 107°

Given that y= 7 cm and θ= 49 °, work out x rounded to 1 DP.<br><br> (not drawn to scale.)
Anastaziya [24]

The value of x in the diagram is 6.1 cm.

<h3>What is right-angle triangle?</h3>

A right-angle triangle is a triangle that has 90° as one of the angles in the triangle.

To calculate the value of x in the right-angled triangle above, we use the formula below

Formula:

  • tanθ = y/x............ Equation 1

Make x the subject of equation 2

  • x = y/tanθ............. Equation 2

From the question,

Given:

  • θ = 49°
  • y = 7 cm

Substitute these values into equation 2

  • x = 7/tan49°
  • x = 7/1.15
  • x = 6.1 cm

Hence, the value of x in the diagram is 6.1 cm.
