Need Further Guidance To Solve The Missing Step In The Proof

Answers

Answer 1

From the question given, we are asked to determine the missing steps to prove that QUAD is a parallelogram.

recall, for a diagram to be a parallelogram, the slope of the vertices must be equal.

So, the missing step is:

line QU is parallel to line AD and line UA is parallel to line DQ because the segments have the same slope.

Therefore, the correct option is A, which is line QU is parallel to line AD and line UA is parallel to line DQ because the segments have the same slope.

Toby eats tacos every 5 days. Toby also drinks horchata every 6 days. If Toby has horchata and tacos today how many days will he have too wait to enjoy his favorite treats on the same day again?

Answers

We are given the following information

Toby eats tacos every 5 days.

Toby also drinks horchata every 6 days.

If Toby has horchata and tacos today how many days will he have to wait to enjoy his favorite treats on the same day again?

We need to find the least common multiple (LCM) of 5 and 6 days.

Multiples of 5 = 5, 10, 15, 20, 25, 30

Multiples of 6 = 6, 12, 18, 24, 30

As you can see, the least common multiple (LCM) of 5 and 6 is 30

Therefore, Toby has to wait for 30 days to enjoy his favorite treats on the same day again.

Last year, Henry had $30,000 to invest. He invested some of it in an account that paid 7% simple interest per year, and he invested the rest in an account that paid 5% simple interest per year. After one year, he received a total of $1760 in interest. How much did he invest in each account? First account: Second account:

Answers

Solution

Step 1

Total amount invested = $30,000

Step 2:

First account

Money invested = m

interest rate = 7%

Time = 1 year

Interest = ?

Second account

Money invested = 30000 - m

interest rate = 5%

Time = 1 year

Interest = ?

Step 3:

Interest received from the first investment

[tex]\begin{gathered} Interest\text{ = }\frac{PRT}{100}\text{ = }\frac{m\times7\times1}{100}\text{ = 0.07m} \\ \end{gathered}[/tex]

Interest received from the second investment

[tex]Interest\text{ = }\frac{PRT}{100}\text{ = }\frac{\lparen30000-m\rparen\times5\times1}{100}\text{ = 0.05\lparen30000 - m\rparen}[/tex]

Step 4:

Total interest = $1760

[tex]\begin{gathered} \text{0.07m + 0.05\lparen30000 - m\rparen = 1760} \\ 0.07m\text{ + 1500 - 0.05m = 1760} \\ 0.02m\text{ = 1760 + 1500} \\ 0.02m\text{ = 260} \\ \text{m = }\frac{260}{0.02} \\ \text{m = \$13000} \end{gathered}[/tex]

Can You Describe A Scale Copy?

Answers

A scale copy is basically to copy the same geometrically figure but at different sizes of the original figure. The copy will be bigger or smaller than the original one. It will depend on the factor to scale the figure.

For example, if we want to duplicate the size of the original figure, we need to multiply by 2 each size of the figure. In this case, the figure is bigger than the original one by a factor of 2.

Conversely, if we need to have a smaller representation of the original one, we can multiply each side of the original figure by a fraction. It could be 1/2, 1/10, 1/75, and even 1/100, and so forth. The factor will depend on the needs about how to represent the original figure on an appropriate scale. In this way, if we have a size of b, we need to multiply it by the factor above mentioned, for instance:

[tex]\frac{1}{2},\frac{1}{10},\frac{1}{75}\frac{1}{100},\frac{1}{500}[/tex]

Scale copy is fundamental in Design, and whenever is necessary to represent the original object on a different scale.

When we add or subtract a constant from each data in a data set, the mean, median and mode change in the same amount.

So if before we had that the mean = 21.5, median = 24.5 and mode = 25 and we add $3 to each data, then all three values change by adding 3:

• new mean, = previous mean + 3 = 21.5 + 3 =, 24.5

The perimeter of a semicircle is 24.672 inches. What is the semicircle's diameter? Use 3.14 for n.

Answers

Given:

The perimeter of a semicircle is 24.672 inches.

Explanation:

To find the semicircle's diameter:

Using the formula of the perimeter of a semicircle,

[tex]\begin{gathered} P=(\pi+2)r \\ 24.672=(3.14+2)r \\ 24.672=(5.14)r \\ r=\frac{24.672}{5.14} \\ r=4.8\text{ inches} \end{gathered}[/tex]

Then, the diameter is,

[tex]\begin{gathered} d=2r \\ d=2(4.8) \\ d=9.6\text{ inches} \end{gathered}[/tex]

Thus, the diameter of the semicircle is d = 9.6 inches.

Suppose that a and b are real numbers with a+5b=10 find the greatest possible value of the expression a*b enter the exact value.

The greatest possible value is ? Which occurs when a= ? And b=?

Answers

The maximum value of (a x b) would be 1.472 at a = 0.8 and b = 1.84.

What is maxima and minima?

In mathematical analysis, the maxima and minima of a function, known collectively as extrema, are the largest and smallest value of the function, either within a given range, or on the entire domain.

Given is a + 5b = 10.

It is given to find the maximum value of the product of [a] and [b].

We can write -

a + 5b = 10

b = 2 - a/5

So, we can write -

a x b as a(2 - a/5)

So, we can write that -

y = f(a) = a(2 - a/5)

Differentiate with respect to [a], we get -

dy/da = a d/da (2 - a/5) + (2 - a/5) d/da (a)

dy/da = a(0 - 1/5) + (2 - a/5)

dy/da = - a/5 + 2 - a/5

dy/da = 2 - 0.4a

For maximum value -

dy/da = 0

2 - 0.4a = 0

2 = 0.4 a

a = 2 x 0.4

a = 0.8

Therefore -

5b = 10 - 0.8

5b = 9.2

b = 1.84

The maximum value of a x b will be -

0.8 x 1.84

1.472

Therefore, the maximum value of (a x b) would be 1.472 at a = 0.8 and b = 1.84.

Given the parametric equations x = t 2 + 2 and y = t 3 − 4t, where −3 ≤ t ≤ 3, which of the following graphs represents the curve and its orientation?

Answers

Hello there. To solve this question, we'll have to remember some properties about orientation of parametric curves and how to determine their graphs.

First, given the parametric equations:

[tex]\begin{gathered} x=t^2+2 \\ y=t^3-4t \end{gathered}[/tex]

We can solve the first equation for t, such that:

[tex]\begin{gathered} t^2+2=x \\ t^2=x-2 \\ t=\pm\sqrt[]{x-2} \end{gathered}[/tex]

Since t is between - 3 and 3, we have to analyze which values of x are possible using the end points:

(-3)² + 2 = 3² + 2 = 9 + 2 = 11

So as you can see, the values of x are

[tex]2\le x\le11[/tex]

Plugging the first solution into the equation for y, we have

[tex]\begin{gathered} _{}y=(\sqrt[]{x-2})^3-4\sqrt[]{x-2}_{} \\ y=(x-6)\sqrt[]{x-2} \end{gathered}[/tex]

And as x is between 2 and 11, we get that y is between

[tex]-15\le y\le15[/tex]

Sketching this curve, we have

With the other solution, we get

[tex]\begin{gathered} _{}y=(-\sqrt[]{x-2})^3-4\cdot(-\sqrt[]{x-2}) \\ y=-(x-2)\sqrt[]{x-2}+4\sqrt[]{x-2} \\ y=(6-x)\sqrt[]{x-2} \end{gathered}[/tex]

The two curves together looks like

Finally, we have to determine the orientation

For this, let's take a point in the first solution, say we take t = 1 then t = 2

Plugging it into the equations, we get

[tex]\begin{gathered} x=1^2+2=1+2=3 \\ y=1^3-4\cdot1=-3 \end{gathered}[/tex]

Now with t = 2

[tex]\begin{gathered} x=2^2+2=4+2=6 \\ y=2^3-4\cdot2=0 \end{gathered}[/tex]

So as t increses, we go from:

So this is the orientation of the curve and it is the answer contained in the fourth option.

"When finding all the unknown values in similar right triangles you have choices: you can useproportional relationships or the Pythagorean Theorem. Which would you use for each of theseexamples, and why?"

Answers

We know that triangles ABC and DEF are similar. So, in order to find all the unknown values we can use proportional relationships because we have all values of the small triangle and at least, one value of the big triangle.

For instance, if we want to know the lenght of segment FD, the following ratio must be preserved:

[tex]\frac{BC}{AC}=\frac{FE}{FD}[/tex]

since BC=5 , AC=4 and EF=10, we have

so ED is equal to

[tex]\begin{gathered} FD=\frac{4\cdot10}{5} \\ FD=\frac{40}{5} \\ FD=8 \end{gathered}[/tex]

Similarly, we can obtain ED as

The area of a rectangle is 50m^2, and the length of the rectangle is 5 m less than three times the width. Find the dimensions of the rectangle.(Length= m)(Width= m)

Answers

Given:

Area of the rectangle is 50 sq. m.

The length of the rectangle is 5 m less than three times the width.

That is,

l=3w-5

To find the dimensions:

The formula for the area of the rectangle is , A=lw

Therefore,

[tex]\begin{gathered} A=(3w-5)() \\ 50=3w^2-5w \\ 3w^2-5w-50=0 \\ (3w-15)(3w+10)=0 \\ 3w=15,3w=-10 \\ w=5,w=-\frac{10}{3} \end{gathered}[/tex]

Since, width can not be negative.

So, -10/3 can be neglected.

Hence, w=5

So, the length is,

[tex]\begin{gathered} l=3(5)-5_{} \\ =15-5 \\ =10 \end{gathered}[/tex]

Hence, the dimensions are, l=10 m and w=5 m.
