Answer:

D.) 256

Step-by-step explanation:

The first week she made 4 hats, the next week she made 4 times as much which is 16( 4x4=16). The third week she made 64 (16x4=64). The fourth week she made 256 (64x4)

Answer:

256 hats.

Step-by-step explanation:

You can see that every week, the number of hats knitted increases times 4;

1st week: 4 hats knitted.

1st week: 4 hats knitted in total.

2nd week: 4 times as many hats knitted the first week; (4 x 4 = 16).

2nd week: 16 hats knitted in total.

3rd week: 4 times as many hats knitted the second week; (16 x 4 = 64).

3rd week: 64 hats knitted in total.

4th week: 4 times as many hats knitted the third week; (64 x 4 = 256).

4th week: 256 hats knitted in total.

Step-by-step explanation:

(1 - cos²A)(1 + tan²A) = tan²A

1 + tan²A - cos²A - cos²A · tan²A = tan²A

1 + tan²A(1 - cos²A) - cos²A = tan²A

1 - cos²A + tan²A(sin²A) = tan²A

sin²A + tan²A(sin²A) = tan²A

sin²A (1 + tan²A) = tan²A

sin²A (sec²A) = tan²A

sin²A (1/cos²A) = tan²A

(sin²A)/(cos²A) = tan²A

tan²A = tan²A → Proved

Answer:

4.) Cost of cordless phone = $55

cost of each additional handset = $25  

Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:

$55 + 3($25) = $55 + $75 = $130

5.) Given the function, f(d ) = .20d + 14, where:

f(d) = global temperature (in Celsius)

d = number of decades  

To evaluate the value of f (d ) at f(10), you'll have to substitute the value of d = 10 as input into the function:

f(10) = .20(10) + 14

f(10) = 2 + 14

f(10) = 16

6.) Value of f(10):

    In 10 decades, the predicted global temperature will be 16° Celsius.

7.) The correct answer is B. The global temperature f(d) depends on the number of decades, d.

Explanation: the independent variable is d →  it is the input of the function. The output primarily depends on the given value of input.

8.) Given the function, f(t ) = 0.2t

where t = represents number of days elapsed since the planting of the seed.

         Evaluate f(40):

        f(40) = 0.2(40)

        f(40) = 8

Answer:  To isolate the variable in ¹/₄ x multiply by 4 or divide by 1

Step-by-step explanation:

              Let                  ¹/₄ x = a

multiply by 4:          4 (¹/₄) x  = 4 a

                                      1  x  = 4 a

divide by 1:                    ¹/₁ x  = ⁴/₁ a

                                          x  = 4a    [x is now isolated]

To isolate the variable in 1/4x multiply by 4 or divide by 1/4

From the question, we have the following parameters that can be used in our computation:

Expression = 1/4x

To isolate the variable in 1/4x, we multiply by 4

So, we have

Expression = 1/4x * 4

Expression = x

OR

To isolate the variable in 1/4x, we divide by 1/4

Expression = 1/4x / 1/4

Expression = x

Answer:

for this problem we use the sine function

[tex] \sin(x) = \frac{opp}{hyp} \\ \sin(38 ) = \frac{x}{100} [/tex]

multiply both sides of the equation by 100

[tex]100 \sin(38) = \frac{100x}{100} [/tex]

100 cancels on the right hand side of the equation

[tex]100 \sin(38) = x \\ x = 61.566\:ft[/tex]

Plug (0,-5) into the equation -

-5 = -5(0)

-5 times 0 is 0

-5 = 0

(0,-5) is NOT a solution to the equation.

Good luck!

Answer:

No, it is not the solution to the equation.

Step-by-step explanation:

(0, -5)

y = -5x

So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.

-5 = -5(0)

-5 = 0

Therefore, (0, -5) is not a solution to the equation

Answer:

1719: 573 =   41.46: 23.93

Answer:

A = 372 m²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₁ the parallel bases

Here h = 12, b₁ = 40 and b₂ = 22 , then

A = [tex]\frac{1}{2}[/tex] × 12 × (40 + 22) = 6 × 62 = 372 m²

Answer:

The slope is (2/5) or 0.40

Step-by-step explanation:

Slope is the rise of the line (y axis) over run (x axis).  Take any two points.  I picked (0,-2) and (5,0).  The run is the change in x, which is (5 - 1) or 5.  The rise for this change in x is (0 -(-2)) = 2.  Rise/Run = 2/5 or 0.40.

Answer:

line 1

Step-by-step explanation:

perpendicular is the opposite so therefore line 1 is the answer

From the given figure, line AB perpendicular to line 1.

We need to check which line is perpendicular to AB.

In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.

From the given figure we can see that line AB perpendicular to line 1.

The line AB perpendicular to line 1, intersect each other and made an angles 90°.

Therefore, from the given figure, line AB perpendicular to line 1.

Answer:

30 degrees

Step-by-step explanation:

Since all triangles' angles add up to 180 degrees, you can add the sum of the angles you already know and subtract it from 180.

126+24=150

180-150=30

so angle Q = 30 degrees

Answer:

Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)

Step-by-step explanation:

All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!
