Answer:

Isosceles Triangle      

Step-by-step explanation:

  • Reflection symmetry exists when the figure can be folded over onto itself along a line. This line is called the line of symmetry.
  • In a regular polygon, the number of lines of symmetry is equal to the number of sides in the polygon.
  • Isosceles triangle is a type of triangle that will always have exactly 1-fold reflection symmetry.
  • 1-fold reflection symmetry means that one line or 1 division can divide the whole figure into two symmetrical parts.
  • An isosceles triangle is a triangle that has two sides of equal length. Isosceles triangle has at least one line of symmetry.

Thus, the answer is Option c) Isosceles triangle.

Mark invests $6,700 in an online savings account which gives 4.2% simple annual interest. He also invests $6,000 in a savings ac
dalvyx [7]

Answer:

$4,221.00 for online and 6,210.00 for the instore

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4.2%/100 = 0.042 per year.

Solving our equation:

A = 6700(1 + (0.042 × 15)) = 10921

A = $10,921.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,700.00 at a rate of 4.2% per year for 15 years is $10,921.00.

Calculation:

First, converting R percent to r a decimal

r = R/100 = 6.9%/100 = 0.069 per year.

Solving our equation:

A = 6000(1 + (0.069 × 15)) = 12210

A = $12,210.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 6.9% per year for 15 years is $12,210.00.

a dime is dropped from a building at 1.024 ft . if the equation for height as a function of time is h(t)=-16t^2+ initial height
babunello [35]

Answer:

The dime hits the ground after 8 sec.

Step-by-step explanation:

Set h(t) = -16t^2 + h(0) equal to 0:  -16t^2 + 1,024 ft = 0, or:

16t^2 = 1,024 ft, or:

 t^2 =  64 ft^2

Then t = +8 sec

The dime hits the ground after 8 sec.
