Step-by-step explanation:

convert to meters

6 dm = 0.6 m

40 mm = 0.04 m

2 m = 2 m

10 cm = 0.1 m

sum

0.6 + 0.04 + 2 + 0.1 =

2.74 m

Answer:

2.74m

Step-by-step explanation:

Convert all values to meters.

6dm = 0.6m

40mm = 0.04m

2m = 2m

10cm = 0.1m

sum = 0.6+0.04+2+0.1

= 2.74

The true statement is the value of f(2) is larger than the value of f(3).

The function is given as:

f(x) = −3x^2 + 4x + 6

Calculate f(2) and f(3), as follows:

f(2) = −3(2)^2 + 4(2) + 6 = 2

f(3) = −3(3)^2 + 4(3) + 6 = -9

By comparison;

f(2) is greater than f(3) because 2 > 9

Hence, the true statement is the value of f(2) is larger than the value of f(3).

The equation of the circle is (x + 7)² + (y + 6)² = 4 if the center and radius are (-7,-6) and 2 respectively.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have center of the circle(h, k) = (-7, -6)

The radius of the circle r = 2

The standard form of a circle:

(x - h)² + (y - k)² = r²

(x - (-7))² + (y - (-6))² = 2²

(x + 7)² + (y + 6)² = 4

Thus, the equation of the circle is (x + 7)² + (y + 6)² = 4 if the center and radius are (-7,-6) and 2 respectively.

The system of equations represented by the graph is the one in option b.

We can see that the graph is:

A solid line with a positive slope, such that the region above the line is shaded.

This is represented by:

y ≥ line.

And we can see a horizontal line at y = 4, the line is dashed and the region below the line is shaded, then we have:

y < 4

Then the system is of the form:

y ≥ line.

y < 4

Answer:

59 degrees

Step-by-step explanation:

Supplemental means that the angles add to 180.

x + y + z = 180

x + y = 2z + 3

Replace x + y  in the top equation with 2z + 3

2z + 3 = z = 180

3x + 3 = 180 Combine the z's.

3x = 177 subtract 3 from both sides

x = 59

Based on the calculations, the amount of money she invested is equal to $3,520.

First of all, we would assign variables to the amount of money that he invested at different interest rates as follows:

Since Lydia invested the same amount of money in both stocks, we have:

x = y     ....equation 1.

At the two interest rates, the total amount Lydia gets is given by:

0.11x + 0.14y = 440     ....equation 2.

Solving the equations simultaneously, we have:

0.11y + 0.14y = 440

0.25y = 440

y = 440/0.25

y = $1,760.

Thus, the total investment is given by:

Total investment = 1760 + 1760

Total investment = $3,520.

Simple interest is interest calculated on the principal portion of a loan or the original contribution to a savings account. Simple interest does not compound, meaning that an account holder will only gain interest on the principal, and a borrower will never have to pay interest on interest already accrued.

We have,

Amount spent each month = $83.42

Interest rate, r = 1.8% = 0.018

Time, n = 3 years

Now,

The total amount collected at the end of the year = $83.42 × 12 = $1001.04

The value of the amount deposited in the bank after 3 years will be

Future value = Present value × ( 1 + r )ⁿ

on substituting the respective values,

we have

Future value = $1001.04 × ( 1 + 0.018 )³

or

Future value = $1,056.07

Hence,

The money he could have at the end of 3 more years will be $1,055.17

A function is a law that relates a dependent and an independent variable.

It is given that f(x) = x³

g(x) = -2x³

When a function is reflected along an axis , the coordinate of that axis remains the same but the coordinate of the other axis becomes negative

So, if x coordinate is transformed to -ve of the parent function , The function is reflected along y axis.

As there is 2 in front of the parent function ,

f'(x) = a f(x) , represents vertical stretch when a >1

The amount of money earned, in continuous compounding, after t years, is given by:

[tex]A(t) = Pe^{rt}[/tex]

In which:

The parameters are given as follows:

A(0) = 20000, r = 0.0297, t = 10.

Hence the worth in 10 years will be given by:

[tex]A(t) = Pe^{rt}[/tex]

[tex]A(10) = 20000e^{0.0297 \times 10}[/tex]

A(10) = $26,916.31.

Now, we find in how many years it will be worth $70,000, as follows:

[tex]A(t) = Pe^{rt}[/tex]

[tex]70000 = 20000e^{0.0297t}[/tex]

[tex]e^{0.0297t} = 3.5[/tex]
