Write sin 64° in terms of cosine.

Answer:

gradient = 1

Step-by-step explanation:

calculate the gradient using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-(-2)}{2-0}[/tex] = [tex]\frac{0+2}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

[tex]\underline{\underline{\large\bf{Solution:-}}}\\[/tex]

[tex]\longrightarrow[/tex]By observing the graph of the line , we can observes that it intersects x- axis at 2 and y -axis at -2 i.e., it passes through (2,0) and (0,-2) respectively.

[tex]\textsf{The gradient of a line passing through two}[/tex][tex]\sf{given \: points \:(x_1,y_1) \:and \:(x_2,y_2) \: is \:given \: by - }[/tex]

[tex]\green{ \underline { \boxed{ \sf{ Gradient =\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]

Here,

Putting Values:-

[tex]\begin{gathered}\\\implies\quad \bf Gradient =\frac{-2-0}{0-2} \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \bf \frac{\cancel{-2}}{\cancel{-2}} \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \bf 1 \\\end{gathered} [/tex]

>>The gradient of the graph shown is 1

Problem 1

Slope = 3/4

Y intercept = -5

You have the right idea for the slope, but I would use a slash as shown above to indicate a fraction. It looks like you're subtracting 3 and 4 based on what you typed in. Though that might be the division symbol (it's a bit blurry so I can't see it fully/clearly)

=============================================

Problem 2

Answer: 14

The rate of change tells us how fast or slow that he's harvesting the crop. It's another way of saying his speed. The equation in this case is y = 14x+120 where 120 is the starting amount and its the y intercept. X represents the number of days, y represents the number of acres harvested.

Problem 3

This problem is cut off so I cannot answer it. It doesn't clarify what "normal temperature" means. Please update.

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

We can put the rate of hours a week as 5. Since in this case hours will substitute for distance, and distance=speed*time, then the amount of hours will be 5*4=20.

edit: mistyped

Answer:

20 hours

Step-by-step explanation:

Given the following question:

5 hours per week
How many hours does she ride in 4 weeks?

We know the amount of hours Wanda rides per week, so this is a simple multiplication problem.

[tex]5h\times4w[/tex]
[tex]5\times4=20[/tex]
[tex]=20[/tex]

Wanda rides her bike for "20 hours" in 4 weeks.

Hope this helps.

Answer:

From the graph and data points, you can observe that Group B has a HIGHER range and has a greater variability. so it's NOT 1. 4. or 3. THEREFORE it's 2.

Explanation:

You start out by finding the mean (finding the sum of the data values and then dividing the sum by the number of data values)

and subtracting the first plot by the last in each graph.

(at least I think)

I've been through this topic. (it was a long time ago since I'm now in highschool so this might be different now as the grading curriculum has changed)

Step-by-step explanation:

.…ye bccc She have 3 sis and they read 2 pages every morning and 4 in the afternoon × 5

Answer:

vanilla=$5 and fruit juice=$3

Step-by-step explanation:

let $x and $y denote the cost of vanilla thickshake and fruit juice respectively.

Now,

$x=$y+2$ (Given)-----(i)

3×$x + 5×$y =30

3×($y+$2)+5×$y=30 (From equation i )

3×$y +$6 + 5×$y = 30

8×$y + $6 = $30

8×$y= $24

.: $y =$3

Then,

From i

$x =$y+$2

=$3+$2

Answer:-3

Step-by-step explanation:

If 3 =h and z=9 you just substitute them into the places of h and z

So 3(8) - 3(9) so 24-27

Answer:

x=7°

Step-by-step explanation:

The figure is a triangle.

1. Triangles's angles add up to 180°.

2. We know that 1 angle measures 104°, so the remaining 2 angles add up to 76°. It is an isosceles triangle, so both of the remaining 2 angles have equal measures.

3. 76÷2=38°.

4. 9x-25°=38°

5. 63°-25°=38°

6. 9x=63°

7. x=7°

Step by step explanation above. Hope it is correct!

C is the correct Chocie; other chocies are incorrect and have nothing to do with the problem

Step-by-step explanation:

Answer:

Deductive reasoning

Step-by-step explanation:

Answer:

Therefore, they can buy

6.36 bats and 12.72gloves

Step-by-step explanation:

Let us represent:

The number of bats purchased = b

The number of gloves purchased = g

We are told in the question that:

The number of bats they will purchase is half the number of gloves

b = 1/2g

b = g/2

g = 2b

The teams plan to purchase bats that cost $60 each and gloves that cost $25 each. they will purchase. If they have $700, how many of each can they buy?

Hence:

$60 × b + $25 × g = $700

= 60b + 25g = 700

We substitute 2b for g

60b + 25(2b) = 700

60b + 50b = 700

110b = 700

b = 700/110

b = 6.3636363636

b = 6.36 bats

Therefore, the number of bats they can buy = 6.36 bats

Remember:

g = 2b

b = 6.36

Hence,

g = 2 × 6.36

g =12.72

Therefore, the number of gloves = 12.72 gloves

Answer:

y = -4

Step-by-step explanation:

Since x and y vary inversely, we have:

xy=k

For x= -2 and y = -8, we have:

⇒  -2×-8=k

⇒  k= 16

For x= -4, we have :

⇒  -4y=16

⇒  y= 16/-4

⇒  y=  -4

[RevyBreeze]

Answer:

y = -4

Step-by-step explanation:

The equation for inverse variation is

xy = k where k is a constant

x=-2 and y = -8  so we can find k

-2 * -8 = k

16 = k

The equation is xy = 16

Know we want to find y when x = -4

-4 *y =16

Divide each side by -4

-4y /-4 = 16/-4

y = -4

Answer:

60

Step-by-step explanation:

all the outer angles have to add up to 360

Answer:

20

Step-by-step explanation:

[tex]\frac{35n}{35} =\frac{700}{35} \\[/tex]

multiply both sides by 35

[tex]35*\frac{35n}{35} = 700 * 35\\35n = 700[/tex]

divide both sides by 35

[tex]n = 20[/tex]

Answer:

N = 20

Step-by-step explanation:

Move all terms to the left

35n/35-(700/35)=0

Add all of the numbers together, and all of the variables

35n/35-20=0

Multiply all of the terms by the denominator

35n-20*35=0

Add all of the numbers together, and all of the variables

35n-700=0

Move all of the terms containing N to the left, all other terms to the right

35n=700

n=700/35

n=20

Answer:

Please find the answer in the explanation

Step-by-step explanation:

Given that Jordan started at her home at point h she ran to the bank library post office at point B the café and then back to her home The coordinates the position in the miles of each of these locations with respect messenger tell which is located at the origin.

The total distance travelled will be the magnitude in miles from point h to B plus the magnitude in miles from point B to the cafe plus magnitude in miles from cafe back to point B plus the magnitude in miles from point B back to point h.

That is,

If the displacement from point h to b = x

And from B to the cafe = y

Then the total distance travelled will be

Distance = 2x + 2y

Perimeter: h + h + g +g = P or 2h + 2g = P

P = 2h + 2g

68.4 = 2(4.7) + 2g

68.4 = 9.4 + 2g

59 = 2g

g = 29.5
