Please help me I’m not good with graphs

Answer:

[tex]3*2=8[/tex]

Step-by-step explanation:

We know that [tex]r*s=s^{r}[/tex], and we want to find [tex]3*2[/tex] using this formula. To do this, notice that [tex]r=3[/tex] and [tex]s=2[/tex], so all we have to do is substitute the given values into the formula. Therefore:

[tex]r*s=s^{r}[/tex]

[tex]3*2=2^{3}[/tex] (Substitute [tex]r=3[/tex] and [tex]s=2[/tex] into [tex]r*s=s^{r}[/tex])

        [tex]=8[/tex] (Simplify)

Hope this helps!

Answer:

C. SAS

Step-by-step explanation:

If you look at both of the triangles carefully, you will see that both side AB and side DC have the same amount of lines. Since they have the same sides, the angle that they share would equal each other as well. The last side is obviously equal to each other because they are the same.

SSS, because all of the sides are the same ; AC = BD , AB = CD , and they both share side BC

Answer:

12/20

Step-by-step explanation:

Cosine is a trigonometric identity. It is a ratio of the adjacent side and hypotenuse of a right triangle.

The adjacent side to angle Θ is 12. The hypotenuse of this triangle is 20.

cosΘ in this case would be 12/20.

Step-by-step explanation:

[tex] = 2\pi \times r = 2\pi \times \frac{16}{2} = 2\pi \times 8 = 50.265 = 50.27[/tex]

To be able to solve clearly this problem, the best thing to do is to plot the graph (see attached pic). From the graph we can see that the points form a trapezoid.

The base is formed by the segment connecting point A and point B.

While the two heights: shorter one by the segment connecting points A and D, and the longer one by the segment connecting points B and C.

The formula for area of trapezoid is given as:

A = b (h1 + h2) / 2

Where,

b = base of the trapezoid  = 3 – (-4) = 7

h1 = shorter height = 2 – (-2) = 4

h2 = longer height = 2 – (-5) = 7

Therefore the area is:

A = 7 (4 + 7) / 2

A = 77 / 2

A = 38.5

Answer:

Step-by-step explanation:

To do this problem you would need to have at least one side length AND the hypotenuse to figure out the other side length.

Answer:

2 shifts

Step-by-step explanation:

Amount earned washes dishes = 12 dollars / hour

Shift duration = 75 minutes

Cost of laundry = 12 quarters per load

Cost of 10 loads of laundry = (10 * 12 quarters) = 120 quarters

1 quarter = 25 cents

120 quarters = (25 * 120) = 3000 cents

100 cents = $1

3000 cents = 3000/ 100 = $30

Hence, to make $30 from washing dishes :

$12 = 1 hour

$30 = x

x = 30 / 12

x = 2.5 hours

1 shift lasts 75 minutes

2.5 hours = (2.5 * 60) = 150 minutes

150 / 75 = 2 shifts

Answer:

She started 4 meters ahead and moves forward 1.5 meters every second.

The rate is 1 and 1/2 meters per second and she did get a head start of 4 meters

Answer:

1st volume = 160

2nd volume = 160 + 54 = 214

3rd volume = 160 + 54 + 32 = 246

4th volume = x + 54 + 32 = 246

Step-by-step explanation:

Given that:

Number of volumes = 4

1st volume = x pages

2nd volume = 54 more = x + 54

3rd volume = 32 more = x + 54 + 32

4th volume = 32 more = x + 54 + 32

Total number of pages = 866

Hence,

1st + 2nd + 3rd + 4th = 866

x + x + 54 + x + 54 + 32 + x + 54 + 32 = 866

4x + 226 = 866

4x = 640

x = 160

1st volume = 160

2nd volume = 160 + 54 = 214

3rd volume = 160 + 54 + 32 = 246

4th volume = x + 54 + 32 = 246

Answer:

x = 67

Step-by-step explanation:

2x - 17 + 63 = 180 {Linear pair}

     2x + 46  = 180    

             2x = 180 - 46

             2x = 134

               x = 134/2

              x = 67

[tex]\color{plum}\bold{x \tt \: = 67}[/tex]

∠63° and ∠(2x-17)° are a linear pair, so their sum will be equal to 180°.

Which means :

[tex] = 63 + 2x - 17 = 180[/tex]

[tex] = 63 + 2x = 180 + 17[/tex]

[tex] = 63 + 2x = 197[/tex]

[tex] = 2x = 197 - 63[/tex]

[tex] = 2x = 134[/tex]

[tex] = x = 67[/tex]

Let us place 67 in the place of x and see if the substitution is equivalent to 180° :

[tex] = 63 + 2 \times 67 - 17 = 180[/tex]

[tex] = 63 + 134 - 17 = 180[/tex]

[tex] = 63 + 117 = 180[/tex]

[tex] = 180 = 180[/tex]

Thus, the value of x we found out is correct.

Therefore, x = 67

Answer:

the width be 70 yards

Step-by-step explanation:

The computation of the width of the field is as follows:

As we know that

The Perimeter of the rectangle is

= 2 × (length + width)

Where

Perimeter is 340 yards

Let us assume the width be x

So, the length would be x + 30

Now put these values to the above formula

340 = 2 × (x + x + 30)

340 = 2 × (2x + 30)

340 = 4x + 60

4x = 280

x = 70

The length would be

= 70 + 30

= 100

Hence, the width be 70 yards

Answer: 1.  7(3+5)= 21+35

2. 15 - 10 = 5 (3-2)

Step-by-step explanation:

1: 7(3+5) = ? + ?

Opening the bracket and multiplying each number by 7

7 x 3 + 7 x 5 = 21 + 35 =56

7(3+5)= 21+35

2.15 - 10 = ? (3-2)

15- 10 = 5  , On the other hand,

3-2 = 1

to make the left hand equivalent to the right hand side , we multiply the difference gotten from 3-2 by 5 so we have

15 - 10 = 5 (3-2)

5=5(1)

5=5

Answer:

648 cups, 3 fluid ounces

Step-by-step explanation:

You need to know that 1 cup = 8 fluid ounces (fl. oz).

convert to fl. oz:

1296 cups = 10368 fl.oz.

total fl.oz. = 10368+6 = 10374

10374 / 2 = 5187 fl.oz.

= 648 cups and 3 fluid ounces

Answer:

  A, B, D

Step-by-step explanation:

A. Multiplication is the same as repeated addition.

B. Multiplying a fraction by an integer effectively multiplies only the numerator. The denominator remains unchanged.

C. (false -- see B)

D. A product is unchanged if a factor is removed from the multiplicand and is applied to the multiplier. (The associative property of multiplication tells you this.)

Answer:

C

Step-by-step explanation:

Since at the 95% confidence, the difference between the number of croaks per hour between southern and northern region frog is lying in the rage 7.1 to 8.1, this shows that the southern region's frogs' croak frequency is highly likely to be greater than that of northern region's frogs' croaks' frequency.

The claim supported by the interval is

Option C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

The interval we obtain at certain confidence tells that the value of the test statistics will lie in that interval with that confidence.

Since the test statistics was measuring the croak frequency difference

with southern - northern, and since at 95% confidence,  the difference will lie in interval (7.1, 8.1), which is positive, thus the frequency of crocks for southern frogs is greater than the frequency of crocks for northern frogs.

Thus,

The claim supported by the interval is

Option C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

Answer:

The required expression which can be used to find the nth term in the sequence is:

[tex]a_n=2n+3[/tex]

Hence, the fourth option i.e. 2n+3 is the correct option.

Step-by-step explanation:

Given the sequence

5, 7, 9, 11,...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]7-5=2,\:\quad \:9-7=2,\:\quad \:11-9=2[/tex]

The difference between all the adjacent terms is the same and equal to

d = 2

So

Thus, the nth term of the sequence is

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substitute a₁ = 5 and d = 2 in the sequence

[tex]a_n=2\left(n-1\right)+5[/tex]

[tex]a_n=2n+3[/tex]

Therefore, the required expression which can be used to find the nth term in the sequence is:

[tex]a_n=2n+3[/tex]

Hence, the fourth option i.e. 2n+3 is the correct option.

Answer:

(x=0, y=11)

(x=2, y=9)

Step-by-step explanation:

first equation substitution for x first.

y=11-x

plug into 2nd equation

(x+2)^2+(11-x-7)^2=20

this should lead you into a quadratics equation.

you get x=0, x=2.

do the same for y value this time, subbing in the x value

(11-y+2)^2+(y-7)^2=20

this also leads into a quad equation

solve and you get y=11, and y=9
