Using N as the center and any radius, draw an arc which intersects NM and NO. Label the interception points P and Q.
With a straightedge, connect points D and E.

Answers

Answer:

Step-by-step explanation:

using N as the center and the same radius as before, draw an arc that intersects NO .Label the arc PQ where Q intersects NO.

Congruent angles have the same measure.

The next step is (b) Using N as the center and the same radius as before, draw an arc that intersects NO. Label the arc PQ where Q intersects NO.

The attached image implies that you have already constructed a straight line NO.

The next step is to construct an arc that intersects line NO

To do this, we make use of the following steps

Measure the distance ABMeasure the distance BDConstruct an arc PQ of length BD using point N as the centerLabel the points of intersection as P and Q

Hence, the next step is (b)

A loan of 43,000 is made of 4% interest, compounded annually. After how many years will the amount due reach $66,000 or more?

Answers

Answer:

10 yrs

Step-by-step explanation:

A=P(1+r/n)^nt, P=initial investment, r=annual interest rate,n=number of compounding periods per year, A=amount after t years

For given problem:

P=37000

r=5.5%=.055

n=1

A=62000

62000=37000(1+.055)^t

62/37=1.055^t

tlog(1.055)=log(62/37)

Using log keys on calculator:

t=log(62/37)/log(1.055)≈10 yrs

Elena began to solve this equation:
12x + 6(4x + 3) =2(6x + 4) – 2
----------------------
3
12x + 6(4x + 3) = 3(2(6x + 4) - 2)
12x + 6(4x + 3) = 6(6x+ 4) – 6
12x + 24x + 18 = 36x + 24 - 6

When she got to the last line she stopped and said the equation is true for all values of x. How could Elena tell?

Answers

Answer:

They have the same slope and y intercept after combining like terms, they are the same line and have infinetely many solutions.

Step-by-step explanation:

If you combine like terms it would give you 36x + 18 = 36x +18,

nThat's infinetely many solutions since they have the same slope and y-intercepts, therefore they are the same line.

The equation has infinitely many solutions. That means equation is true for all values of x.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

We have equation;

12x + 6(4x + 3) =2(6x + 4) – 2

And Elena solved,

12x + 24x + 18 = 36x + 24 - 6

Now, we will solve further,

36x + 18 = 36x + 18

That means equations are equivalent.

And there are two equations and one unknown.

So equation has infinitely many solutions.

Therefore, the equation has infinitely many solutions. That means equation is true for all values of x.

The number of people who have heard a rumor often grows exponentially. Consider a rumor that starts with 3 people and where the number of people who have heard it doubles each day. How many people would know the rumor after 20 days?

Answers

Answer:

3.9125 × 10⁵² people

Step-by-step explanation:

A rumor starts with 3 people and the number of people who heard it doubles each day.

How many people would have heard the rumor after 20 days?

To calculate exponential growth, we use the formula:

[tex]y (t) = ae^{kt}[/tex]

where;

a = value at the start =3

k = growth rate = 2×3 = 6

t = time = 20 days

y(t) = value of the population at the given time (t) =??

[tex]y(t) = 3 \times e^{6\times 20}[/tex]

y(t) = 3.9125 × 10⁵² people

A biologist recorded the population growth of two species of frogs in a pond area starting in 2010. The first species started with 42 frogs and increased by 6 frogs per year. The second species started with 30 frogs and increased by 8 frogs per year.

make an equation modeling equal populations of the frogs at T years after 2010.

Answers

Answer:

42 + 6t = 30 + 8t

Step-by-step explanation:

1st species starts with 42f. They gain 6 frogs a year, with the letter 't' representing years. 42 + 6t would be the rate for the first species. 2nd species starts with 30 and gains 8 frogs a year, the letter 't' also representing years. So 30 + 8t would be the rate. Writing an equation to find when the groups are equal, it would result in 42 + 6t = 30 + 8t

To find the answer to this,

42 + 6t = 30 + 8t

Step 1: Subtract 30 from both sides

42-30 +6t = 30-30 + 8t

12 + 6t = 8t

Step 2: subtract 6t from both sides

12 + 6t-6t = 8t-6t

12 = 2t

Step 3: divide both sides by 2

12/2 = 2t/2

6 = t

Step 4 : Rearrange

t = 6

Hope this helps!

The value of x for the function g(x)=-2x+3 is 3.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

g(x)=-2x+3

Now, for g(x) = -3 we have

-2x+ 3 = -3

Now, Subtract 3 from both side

-2x + 3 - 3 = -3 -3

-2x = -6

Divide both side by (-2) we get

-2x / (-2) = -6 / (-2)

x = 3

Hence, the value of x is 3.
