Answer:

65 degrees

Step-by-step explanation:

Relative to angle A, you are given the measure of the opposite side and the hypotenuse of the right triangle. When it comes to right triangles, we know through our trig identities that the sin of an angle is equivalent to the length of the opposite side over the hypotenuse. Therefore, we can use trig to solve this problem:

[tex]sinA=\frac{a}{c}[/tex]

If we sub in the values of a and c which are given to us, we get the following:

[tex]sinA=\frac{10}{11}[/tex]

To solve for A, we can take arcsin(10/11) because arcsin is inverse:

[tex]A=arcsin(\frac{10}{11} )[/tex]

Using a calculator, we get that A is approximately 65 degrees

Answer:

3.5kg

Step-by-step explanation:

Let original weight  of grapes in box be X and weight of grapes in basket be Y.

From the first sentence
X = 2Y  (weight in box = 2 times weight in basket)   --- (1)

If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2

From the second statement

Y + 2 = X + 0.5

Subtracting Y from the LHS gives 2 = X - Y + 0.5

Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5  --- (2)

Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg

But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg

The hull speed of a boat when given by the function v = 1.34√l, makes the expression represent the speed of Santa Monica, v = a√b, with a = 1.34, and b = ln - 10, where lₙ is the length of the Nina Pinta. The restriction on lₙ is that lₙ > 10.

In the question, we are asked to express the speed of the boat of Santa Monica in terms of the length, lₙ of the Nina Pinta.

We are informed that the function is represented as v = a√b, for the speed of Santa Monica.

We are given that the hull speed of a boat of length l is given as v = 1.34√l.

Comparing, the speed of Santa Monica v = a√b, to the general formula v = 1.34√l, we get:

a = 1.34, and

b = the length of the boat of Santa Monica.

The length of the boat of Santa Monica is 10 ft. shorter than of Nina Pinta.

Thus, b = lₙ - 10, where lₙ is the length of the boat of Nina Pinta.

Since b has to be positive, as the function involves square root over b, lₙ - 10 > 0, or, lₙ > 10, is the restriction on the length of the boat of Nina Pinta.

Thus, the hull speed of a boat when given by the function v = 1.34√l, makes the expression represent the speed of Santa Monica, v = a√b, with a = 1.34, and b = ln - 10, where lₙ is the length of the Nina Pinta. The restriction on lₙ is that lₙ > 10.

We cannot express the function [tex]x^{2} -sin(x+y)=1[/tex] in y=f(x) form it has an implicit function.

Given function [tex]x^{2} -sin(x+y)=1[/tex] and dy/dx=2x sec(x+y)-1

A relation is said to be an implicit solution of a differential equation involving x,y and derivatives of y with respect to x if defined explicit solution. In other words  the function which cannot be written as y=f(x).

Function is a relationship between two or more variables which have one value for each value of x.

We have to first differentiate the function with respect to x.

[tex]x^{2} -sin(x+y)=1[/tex]

2x-cos(x+y)(1+dy/dx)=0

2x-cos(x+y)+cos(x+y)dy/dx=0

cos(x+y) dy/dx=cos(x+y)-2x

dy/dx={cos(x+y)-2x}/cos(x+y)

dy/dx=cos(x+y)/cos(x+y)-2x/cos(x+y)

dy/dx=1-2x cos(x+y)

The given solution is incorrect.

when we solve the function to collect the variable y in one side we cannot be able to do that.

2×-5=-8 and 2×-5/8=-1.25

Answer:

x = 10.5

Step-by-step explanation:

I'll assume this is the equation: (2x-5)/8 = 2

(2x-5)/8 = 2

(2x-5) = 16   [Multiply both sides by 8]

2x = 21        [Add 5 to both sides]

x = (21/2)    [Divide both sides by 2]

or x = 10.5

So, the next four terms are:

Next 1 = 1/5 * 1875 = 375

Next 2 = 1/5 * 375 = 75

Next 3 = 1/5 * 75 = 15

Answer:

x = 9

Step-by-step explanation:

since the terms are in AP then there is a common difference between consecutive terms, that is

a₂ - a₁ = a₃ - a₂ ( substitute values )

x - 7 = 11 - x ( add x to both sides )

2x - 7 = 11 ( add 7 to both sides )

2x = 18 ( divide both sides by 2 )

x = 9

Answer:

9

Step-by-step explanation:

The nth term of an AP has the formular

a+ ( n - 1 ) d

a = first term

n = number of terms

d = common difference

common difference d = T2 - T1 0r T3 - T2

d = x - 7 or 11 - x

Therefore,

3rd term

a + (3 - 1)d

a + 2d

Hence,

7 +2d = 11

substitute the value of d above

7 + 2 (x -7) = 11

7 + 2x - 14 = 11

2x = 11 +14 -7

2x = 18

dividing bothsides by 2

x = 18/2

Answer:

y = - x² + 1

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (0, 1 ) , then

y = a(x - 0)² + 1 = ax² + 1

to find a substitute any other point that lies on the graph into the equation

using (1, 0 ) , then

0 = a(1)² + 1 ( subtract 1 from both sides )

- 1 = a

y = - x² + 1 ← equation of graph

Answer:

- x² + 1

Step-by-step explanation:

the vertex of the graph is (0 , 1)

Then the equation of the graph has this form :

(x - 0)² + 1  or  - (x - 0)² + 1

Since the parabola is opening down

Then

the equation of the graph is :

- (x - 0)² + 1 = - x² + 1

The total angle of each diamond is 360 degrees. The opposite angles of the diamond are congruent.

Congruency: In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

The two adjacent angles are 2x + 20 degrees and 50 degrees.

Opposite angles measure 2x + 20 and 50 degrees.

The sum of the angles of each rectangle is 360

2x + 20 + 50 + 2x + 20 + 50 = 360

Add the line terms and subtract

4x + 140 = 360

4x = 2

Divide both sides by 4

Answer:

20 km rate should 7.76

Step-by-step explanation:

Definitions

The variable rate is the rate for every km.

The fixed rate is what is charged for someone just getting on their bicycle.

Givens

Length of race = 6 km

variable rate = 0.22 / km

fixed rate = x

Total cost = 4.68

Formula

Total cost = fixed rate + variable rate * distance

Solution

4.68 = 6*0.22 + x

4.68 = 1.32 + x                       Subtract 1.32 from both sides.

4.68 - 1.32 = 1.32 - 1.32 + x   Combine

3,36 = x

The fixed rate is 3.36

Before getting the answer to the question asked, we should see if we get the same fixed rate for 24 km

Check

Total Cost = fixed rate + variable rate*distance

Total Cost = 8.64

fixed rate = x

variable rate = 0.22

distance = 24 km

8.64 = x + 0.22 * 24                Combine

8.64 = x + 5,28                        Subtract 5.28 from both sides

8.54 - 5,28 = x + 5.28 - 5,28  Combine

3.36 = x which agrees with our first calculation for the fixed rate.

Answer

y = 3.36 + 20*0.22

y = 3.36 + 4.4                           Combine

y = 7.76
