Help please how do I find x and y

Answer:

Step-by-step explanation:

Answer:

First angle would be 31°, second angle would be 59°

Step-by-step explanation:

You can use the equation 90° = a + (2a - 3°), where a is the measure of your smaller angle.

simplify:

90° = 3a - 3°

93° = 3a

31° = a

let your second angle equal (2a - 3°)

(2(31°) - 3°) = 59°

We have proved that f o g is uniformly continuous on R, as desired.

F(g(x)) or (f g)(x) denotes the combination of the functions f(x) and g(x), where g(x) acts first. It brings together two or more functions to produce a new function.

To prove that the composite function f o g is uniformly continuous on R, we need to show that for any ε > 0, there exists a δ > 0 such that for any x, y ∈ R,

| x - y | < δ implies | (f o g)(x) - (f o g)(y) | < ε

We can start by using the uniform continuity of g to choose a δ1 > 0 such that for any x, y ∈ R,

| x - y | < δ1 implies | g(x) - g(y) | < ε

Now, we can use the uniform continuity of f with ε replaced by δ₁ to choose a δ₂ > 0 such that for any u, v ∈ R,

| u - v | < δ₂ implies | f(u) - f(v) | < δ₁

Finally, we can choose δ = δ₂ to show that for any x, y ∈ R,

| x - y | < δ implies | (f o g)(x) - (f o g)(y) | < ε

To see why this is true, let's assume that | x - y | < δ. Then, by the definition of the composite function,

(f o g)(x) - (f o g)(y) = f(g(x)) - f(g(y))

Now, since | g(x) - g(y) | < δ₁, we know that | f(g(x)) - f(g(y)) | < ε, by the choice of δ₁. And since | x - y | < δ₂ implies | g(x) - g(y) | < δ₁, we have shown that

| x - y | < δ₂ implies | (f o g)(x) - (f o g)(y) | < ε

Therefore, we have proved that f o g is uniformly continuous on R, as desired.

Answer:

35°

Step-by-step explanation:

angle3 = 3x-7

the two angles are complementary  ( they sum to 90)

4x-1     +     3x-7      = 90

The link between s, t, and u is therefore u2= t2+s2 and provides the answer to the triangle problem.

A triangle is a polygon since it has three parts and three vertices. It is a basic geometric shape. A triangle with the corners A, B, & C is referred to as a triangle ABC. A singular plane & triangle in Geometric shapes are found so when three components are not collinear. Due to its right side and three corners, triangles are considered polygons. The corners of a triangle are defined as the locations at which its three sides meet. 180 degrees is obtained by multiplying three triangle angles.

For the function g(x,y) = ln(x^2 +y^2 -9), the domain is all values of x and y that make the argument inside the natural logarithm non-negative.


To find and sketch the domain and range of the given functions, we'll first identify the domain and range for each function and then sketch them. Let's start with the first function, g(x,y):

g(x, y) = ln(x^2 + y^2 - 9)

1. Domain: The domain is the set of all possible input values (x, y) for which the function is defined. The natural logarithm function is only defined for positive numbers. Therefore, we need x^2 + y^2 - 9 > 0.

x^2 + y^2 - 9 > 0
x^2 + y^2 > 9

This inequality represents the points outside a circle with a radius of 3 centered at the origin. Thus, the domain is the set of all points (x, y) outside this circle.

2. Range: The range is the set of all possible output values for the function. Since the natural logarithm function has a range of all real numbers when its input is positive, the range of g(x, y) will also be all real numbers.

Now let's sketch the domain and range of g(x, y):

Domain: Draw a circle with a radius of 3 centered at the origin. Shade the area outside the circle to represent the domain.
Range: Since the range is all real numbers, you can simply write "R" to represent the range.

As for the second function, f(x, y, z), there is no given function definition.

Answer: 0.84375

Step-by-step explanation:

1. x = 5.4n

2. 5.4n + n = 5.4

3. n(6.4) = 5.4

4. n = 0.84375

DOUBLE CHECK

x = 5.4(0.84375)

x = 4.55625

4.55625 + 0.84375 = 5.4

0.84375 = 5.4 - 4.55625

0.84375 = 0.84375

The solution is, : for 0.84375 = N such that x+N=5.4 and x/n=5.4 are equivalent equations.

Answer:

She has 27 quarters

Step-by-step explanation:

Let:

x = Number of nickels

y = Number of quarters

US$0.05 = 5 cents = monetary value of a nickel

US$0.25 = 25 cents = monetary value of a quarter

                      x + y = 68

                     x = 68 - y  ---- --------  (equation i)

                0.05x + 0.25y = 8.80----- (equation ii)

These two are linear simultaneous equations, which can be solved either by substitution, elimination or graphical method.

Substitution method:

Substitute (equation i) into (equation ii) to solve for y:

0.05(68 - y) + 0.25y = 8.80

Expand the brackets by applying the Distributive Law and then bring all the like terms together. y needs to be isolated and made the subject of the equation:

= 3.4 - 0.05y + 0.25y = 8.80

= 0.25y - 0.05y = 8.80 - 3.40

= 0.20y = 5.40

= y = \(\frac{5.40}{0.20}\)

∴ y = number of quarters = 27

Using the slope line formula,

The slope of line y = mx is 1.0315.

We have given that,

parabola equation is y = 5x - 3x²

line passing through origin is in the form of y = mx

==> mx = 5x - 3x²

==> 3x²+ mx - 5x = 0

==> 3x² + x(m -5) = 0

==> x(3x + (m -5)) = 0

==> x = 0 , x = (5 -m)/3

The total area of the bounded region is then the integral of 5x - 3x² from x = 0 to x = (5-m)/3

Area under y = 5x - 3x2 and y = mx is (125/54)/2 = 125/108

==> [0 to (5 -m)/3] ∫(5x - 3x²-mx )dx = 125/108

==> [0 to (5 -m)/3]∫( (5 - m)x - 3x2 )dx = 125/108

==> [0 to (5 -m)/3] ((5 - m)x²/2 - x³ )= 125/108

==> (5 - m)[(5 -m)/3]²/2 - ((5 -m)/3)³ = 125/108

==> (5 -m)³/18 - (5 -m)³/27 = 125/108

==> (5 -m)³/54 = 125/108

==> (5 -m)³ = 125/2

==> (5 -m) = 3.9685

==> m = 5 - 3.9685

==> m = 1.0315

Hence slope of line = 1.0315

Step-by-step explanation:

The probability that none of the 4 light bulbs work is 2.56%.

As per the given information, the probability that an individual light bulb works is 0.6.

Therefore, the probability that it does not work (i.e., fails) is:

1 - 0.6 = 0.4

Since each light bulb works independently of the other light bulbs, the probability that none of the 4 light bulbs work is the product of the individual probabilities that each light bulb fails.

Calculated as,

P(none work) = P(first fails) × P(second fails) × P(third fails) × P(fourth fails)

P(none work) = 0.4 × 0.4 × 0.4 × 0.4

P(none work) = 0.0256

Therefore, the probability that none of the 4 light bulbs work is 0.0256 or approximately 2.56%.

Each bus can carry 14 students and each van can carry 6 students.

Let's assume that a van can carry 'v' students.

Let's assume that a bus can carry 'b' students.

Using this notation, we can set up the following system of equations:

For the first high school:

8v + 9b = 228

For the second high school:

4v + 5b = 124

We have two equations and two unknowns, so we can solve for 'v' and 'b'.

To do this, we can start by solving the second equation for 'b':

5b = 124 - 4v

b = (124 - 4v)/5

We can substitute this expression for 'b' into the first equation:

8v + 9((124 - 4v)/5) = 228

Multiplying both sides by 5 to eliminate the fraction:

40v + 9(124 - 4v) = 1140

Distributing the 9:

40v + 1116 - 36v = 1140

Simplifying:

4v = 24

v = 6

Substituting this value of 'v' into the equation for 'b':

5b = 124 - 4(6)

b = 14

Therefore, a van can carry 6 students, and a bus can carry 14 students.

So the answer is: Each bus can carry 14 students and each van can carry 6 students.
