[tex]\huge\boxed{\sf 9300\ m\²}[/tex]

Step-by-step explanation:

The figure is made up of:

Formula for area of rectangle:

Formula for Area of triangle:

Area of rectangle:

Length = 90 m

Width = 70 m

= Length × Width

= 90 × 70

= 6300 m²

Area of Triangle:

Base = 170 - 70 = 100 m

Height = 90 - 30 = 60 m

[tex]\displaystyle =\frac{1}{2} (Base)(Height)\\\\= \frac{1}{2} (100)(60)\\\\= (50)(60)\\\\= 3000 \ m^2[/tex]

Total Area of the figure:

= 6300 + 3000

= 9300 m²

Answer: $1,271.88

Step-by-step explanation:

        The total cost of the camera with sales tax included will be 100% plus our sales tax:

100% + 9.75% = 109.75%

        Dividing a percent (%) by 100 gives us a decimal:

109.75% / 100 = 1.975

        We can multiply this decimal by the listed price of the camera to find our answer

643.99 * 1.975 = $1,271.88

     The camera will cost $1,271.88 with sales tax.

Answer:

I'm going to assume the # is meant $, if that is the case then the trader made 8% profit

Step-by-step explanation:

200 out of 2500 is basically 200/2500. 200 divided by 2500 is 0.08, and to find the percent of a number you have to multiply it by ten (or just move the decimal two places to the right) 0.08 multiplied by 10 would give you 8, so the answer is 8 percent. Hope this helps!

Answer: ok well the answer is 631 if it were rounded it would be 630

Answer:

Exponential

Step-by-step explanation:

The function g(x) described by the given table of values is most likely an exponential function because x increases by a constant factor and the values of g(x) increase or decrease by a consistent factor. This behavior aligns with the characteristics of an exponential function, where the variable x appears in the exponent. I put polynomial as my answer on the test and got it incorrect and then realized the answer was exponential.

Answer:

[tex]50\; {\rm ft} \times 50\; {\rm ft}[/tex] would maximize the area for a rectangle with the given circumference of [tex]200\; {\rm ft}[/tex]. (Note, that a circle of the same circumference would have an even larger area.)

Step-by-step explanation:

Assume that the base of the house is a rectangle. Let the length of the two sides be [tex]x\; {\rm ft}[/tex] and [tex]y\; {\rm ft}[/tex], respectively. The goal is to find the [tex]x[/tex] and [tex]y[/tex] that:

[tex]\begin{aligned} \text{maximize} \quad & x\, y \\ \text{subject to} \quad & 2\, (x + y) = 200 \\ & x > 0 \\ & y > 0 \end{aligned}[/tex].

Using the equality constraint [tex]2\, (x + y) = 200[/tex] (or [tex]x + y = 100[/tex]), the variable [tex]y[/tex] could be replaced with [tex](100 - x)[/tex] to obtain an equivalent problem of only one variable:

[tex]\begin{aligned} \text{maximize} \quad & x\, (100 - x) \\ \text{subject to} \quad & x > 0 \\ & (100 - x) > 0 \end{aligned}[/tex].

Simplify to obtain:

[tex]\begin{aligned} \text{maximize} \quad & -x^{2} + 100\, x \\ \text{subject to} \quad & x > 0 \\ & x < 100 \end{aligned}[/tex].

The objective function of this problem is [tex]f(x) = -x^{2} + 100\, x[/tex]. Derivatives of this function include

Since [tex]f^{\prime\prime}(x)[/tex] is constantly less than [tex]0[/tex], [tex]f(x)[/tex] is concave and would be maximized when [tex]f^{\prime}(x) = 0[/tex].

Setting [tex]f^{\prime}(x) = -2\, x + 100[/tex] to [tex]0[/tex] and solving for [tex]x[/tex] gives:

[tex]-2\, x + 100 = 0[/tex].

[tex]x = 50[/tex].

Notice that [tex]x = 50[/tex] satisfies both constraints: [tex]x > 0[/tex] and [tex]x < 100[/tex]. Therefore, [tex]x = 50[/tex] is indeed the solution that maximizes the area [tex]f(x) = -x^{2} + 100\, x[/tex] while at the same time meeting the requirements.

With the length of one side being [tex]x = 50[/tex] ([tex]50\; {\rm ft}[/tex],) the length of the other side would be [tex]100 - x = 50[/tex] ([tex]50\; {\rm ft}\![/tex].) Hence, a rectangular house of dimensions [tex]50\; {\rm ft} \times 50\; {\rm ft}[/tex] would maximize the area under the given requirements.

Focus (-2,0)

Answer:

(-2, 0)

Step-by-step explanation:

Standard form of a parabola with a horizontal axis of symmetry:

[tex](y-k)^2=4p(x-h)\quad \textsf{where}\:p\neq 0[/tex]

[tex]\textsf{Vertex}=(h, k)[/tex]

[tex]\textsf{Focus}=(h+p,k)[/tex]

Given equation:

[tex]x=-\dfrac18y^2[/tex]

Rewrite in standard form:

[tex]\implies (x-0)=-\dfrac18(y-0)^2[/tex]

[tex]\implies -8(x-0)=(y-0)^2[/tex]

[tex]\implies (y-0)^2=-8(x-0)[/tex]

Comparing with the general standard form:

Therefore:

[tex]\textsf{Vertex }(h,k)=(0,0)[/tex]

[tex]\textsf{Focus }(h+p,k)=(0-2,0)=(-2,0)[/tex]

Step-by-step explanation:

Answer:

To calculate compounded interest, use the compound interest formula.

A(t)=P(1+rn)n⋅t

Recognize the information given in the problem.

P=2560,r=0.035,n=1,t=4

Substitute the values into the appropriate position in the formula.

A(4)=2560(1+0.0351)1⋅4

Simplify by multiplying and dividing by 1.

A(4)=2560(1+0.035)4

Simplify using the order of operations.

A(4)=$2,937.66

The balance at the end of 4 years would be $2,937.66.

Answer:

A) from year 1 to year 2

Step-by-step explanation:

Answer:

1.

First, I would solve for ACB.

Calculations:

63° = y?

I would do that because I know that angle 'y' is vertical to 63°, which is given. (Also vertical angles are congruent, meaning that the measure the same degrees).

2.

Second, I would solve for BAC.

Calculations:

x + 63 + 85 = 180

x + 148 = 180

-148        -148

x = 32°

I would do that because I know that there are two given angles so I could easily solve for the leftover angle, 'z', using the a + b + c = 180° formula.

3.

Next, I would solve for CED.

Calculations:

x + 130 = 180

-130        -130

x = 50°

I would do that because I know finding this angle will help me find angle CDE.

4.

Finally, I would solve for CDE.

Calculations:

x + 63 + 50 = 180

x + 113 = 180

-113        -113

x = 67°

I would do that because I know there are now two given angles so I could easily solve for the leftover angle, x, using the a + b + c = 180° formula.

The new perimeter of the rectangle if the dimensions are quadrupled would be 72 inches.

The perimeter is always obtained by adding all the sides. This means the possible side lengths of the original rectangle are:

5 inches x 4 = 20 inches

4 iches x 4 = 16 inches

20 + 20 + 16 +16= =72 inches

Answer:

7 3/4

Step-by-step explanation:

Method 1:

Step 1: Instead of subtracting you distribute the minus sign to the number in the parenthesis

4 1/2 - (-3 1/4) = 4 1/2 + 3 1/4

Step 2: Then you can just add

4 1/2 + 3 1/4= 7 3/4

Method 2:

If you dont know fractions transfer them into decimals. 1/2 = 0.5 and 1/4 = 0.25

Step 1: Instead of subtracting you distribute the minus sign to the number in the parenthesis

4.5 - (-3.25) = 4.5 + 3.25

Step 2: Add the numbers

4.5 + 3.25= 7.75

Step 3: Convert the decimal back into a fraction

7.75= 7 3/4

Answer:

31/40

Step-by-step explanation:

Given expression:

[tex]\dfrac{2}{5} + \dfrac{3}{8}[/tex]

Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.

The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.

Multiply the denominators with such a number that is equivalent to 40.

Note: The number you are multiplying should also be multiplied to the numerator.

[tex]\rightarrow \dfrac{2 \times 8}{5 \times 8} + \dfrac{3 \times 5}{8 \times 5}[/tex]

[tex]\rightarrow \dfrac{16}{40} + \dfrac{15}{40}[/tex]

Finally, simplify the expression to determine the solution.

[tex]\rightarrow \dfrac{31}{40}[/tex]

Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.

Ah yes, adding fractions! Adding fractions can be a bit of a pain.

So, we have  [tex]\frac{2}{5} + \frac{3}{8}[/tex].

To add fractions, the bottoms, or denominators, must be the same number. So we must multiply the fractions by certain numbers to make the denominators the same number. So let's go easy and make the denominator 40, because 8 goes into 40 and so does 5. So, to make 8 become 40, we'll multiply the whole fraction by 5. For 5, we'll multiply by 8.

[tex]5 * \frac{3}{8} = \frac{15}{40}[/tex]

[tex]8 * \frac{2}{5} = \frac{16}{40}[/tex]

Now we'll add the two fractions. When we add fractions we only add the tops, the numerators.

[tex]\frac{15}{40}+\frac{16}{40} = \frac{31}{40}[/tex]

Then we must reduce (or try to reduce). This fraction cannot be reduced, so the answer is simply  [tex]\frac{31}{40}[/tex].

I hope this helps you understand.
