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.

A study of the annual population of butterflies in the country park shows the population,B(t), can be represented by the functio
pav-90 [236]

Given:

Annual population of butterflies after t years is

B(t)=137(1.085)^t

To find:

The growth rate.

Solution:

The general exponential function is

f(t)=a(1+r)^t        ...(i)

where, a is initial value, t is time and r is growth rate.

We have,

B(t)=137(1.085)^t

It can be written as

B(t)=137(1+0.085)^t           ...(ii)

On comparing (i) and (ii), we get

Initial value : a=137

Growth rate : r=0.085=8.5\%

Therefore, the growth rate is 8.5%.

Which equation has exactly one solution?
ziro4ka [17]

Answer:

  The answer is D

Step-by-step explanation:

9(x + -3) + 28 = 4x + -3

Reorder the terms:

9(-3 + x) + 28 = 4x + -3

(-3 * 9 + x * 9) + 28 = 4x + -3

(-27 + 9x) + 28 = 4x + -3

Reorder the terms:

-27 + 28 + 9x = 4x + -3

Combine like terms: -27 + 28 = 1

1 + 9x = 4x + -3

Reorder the terms:

1 + 9x = -3 + 4x

Solving

1 + 9x = -3 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

1 + 9x + -4x = -3 + 4x + -4x

Combine like terms: 9x + -4x = 5x

1 + 5x = -3 + 4x + -4x

Combine like terms: 4x + -4x = 0

1 + 5x = -3 + 0

1 + 5x = -3

Add '-1' to each side of the equation.

1 + -1 + 5x = -3 + -1

Combine like terms: 1 + -1 = 0

0 + 5x = -3 + -1

5x = -3 + -1

Combine like terms: -3 + -1 = -4

5x = -4

Divide each side by '5'.

x = -0.8

Simplifying

x = -0.8

The area of the rectangular faces of the box are shown . What is the volume of the box
Gnoma [55]
Label the 3 distinct sides of the box.  I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:

ab=54 in^2
ac=90 in^2
bc=60 in^2

Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c.  Then the volume of the box is a*b*c.

Example:  bc = 90, but c = 60/b.  You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.

Continuing this procedure, I determined that a=9, b=6 and c=10.  Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)

In this scatterplot the individuals are states. The variable "cig" is the number of cigarettes sold per person in the state in 1
Ipatiy [6.2K]

Answer:

e= -5.41

Step-by-step explanation:

Hello!

In linear regression, a residual value is a distance between the observed values and the regression line.

The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).

e= Y - ^Y

e= 15.92 - 21.33 = -5.41

I hope it helps!
