Answer:
The value of x will be:
[tex]x=22\sqrt{2}[/tex]
or
[tex]x = 31.1[/tex]
Step-by-step explanation:
Given
a = 22b = 22To determine
hypotenuse x = ?
For a right-angled triangle with sides, a and b the hypotenuse c is defined as
[tex]c=\sqrt{a^2+b^2}[/tex]
substituting a = 22, b = 22 and c = x
[tex]x=\sqrt{22^2+22^2}[/tex]
[tex]x=\sqrt{22^2\cdot \:2}[/tex]
Apply radical rule: [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]
[tex]x=\sqrt{2}\sqrt{22^2}[/tex]
[tex]x=22\sqrt{2}[/tex]
or
[tex]x = 31.1[/tex]
Therefore, the value of x will be:
[tex]x=22\sqrt{2}[/tex]
or
[tex]x = 31.1[/tex]

what is the rate of change of the function? -2, -1/2,1/2,2?
Given:
The graph of linear function.
To find:
The rate of change the given linear function.
Solution:
From the given graph it is clear that the line passes through the points (0,1) and (1,-1). So, rate of change is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-1-1}{1-0}[/tex]
[tex]m=\dfrac{-2}{1}[/tex]
[tex]m=-2[/tex]
Therefore, the rate of change of the given linear function is -2. Hence, the correct option is A.
The graph shows a journey in a car. Which of the statements most likely describes the journey at the portion of the graph labeled K?
a. The car travels the same distance per unit of time because the portion shows a linear, increasing function.
b. The car travels different distances per unit of time because the portion shows a linear, increasing function.
c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.
d. The car travels the same distance per unit of time because the portion shows a nonlinear, increasing function.
Answer:
c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.
Step-by-step explanation:
We are given the graph of a function of the distance in function of the time.
We want to study the graph during the part of the graph labeled K, which is non-linear, meaning that the accelaration is not constant. This means that the car travels different distances per unit of time, and the correct answer is:
c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.
URGENT! PLEASE HELP!
Answer:
Let's define the East as the x-axis, and the North as the y-axis
Now we can write the speed of the plane as:
(Vx, Vy)
Such that the total velocity of the plane is 350mph
This means that, if the plane flies at an angle of A degrees from the East, then:
Vx = 350mph*cos(A)
Vy = 350mph*sin(A)
We know that the speed of the wind is 65mph at 43° North from East.
This velocity, (Wx, Wy), can be written in components as:
Wx = 65mph*cos(43°) = 47.54 mph
Wy = 65mph*sin(43°) = 44.33 mph
Now, when the plane flies with the wind, the velocity of the plane will be equal to the velocity of the plane plus the velocity of the wind.
This is:
Velocity = (Vx, Vy) + (Wx, Wy) = (Vx + Wx, Vy + Wy)
The plane wants to keep going to the East, then the y-component must vanish (remember that the y-component is the one associated with the North)
Then we must have that:
Vy + Wy = 0
replacing the correspondent values, we have:
350mph*sin(A) + 44.33 mph = 0
350mph*sin(A) = -44.33 mph
Sin(A) = -44.33 mph/350mph
A = Arcsin(-44.33 mph/350mph) = -7.27°
This means that the plane must fly at -7.27° degrees North of East (Or 7.27° South of East)
That is the direction at which the plane must fly.

4cos4(x)-5cos2(x)+1=0 from[0,2pi]
If you could can you give steps please
Answer:
x = {0, π/3, π, 4π/3}
Step-by-step explanation:
4cos⁴(x) - 5cos²(x) + 1 = 0
(u² - 1)(4u² - 1) = 0
u² - 1 = 0
u² = 1
u = ± 1
cos x = ± 1
=> x = 0 or π
4u² - 1 = 0
4u² = 1
u² = 1/4
u = ± 1/2
cos x = ± 1/2
=> x = π/3 or 4π/3
Therefore, x = {0, π/3, π, 4π/3}.

Answer:
5 and 5b: y=-2x+10
5a: y-2=-2(x-6)
Step-by-step explanation:
We can use the mentioned data points to identify the slope. Time will always the x coordinate/axis, so gallons will be the y coordinate/axis. As you probably already know, slope is rise over run, so we can measure the change in y over the change in x, or we can do [tex]\frac{y-y_{1}}{x-x{1}}[/tex]. When we plug in our points, (2,6) and (5,0), we get [tex]\frac{6-0}{2-5}[/tex], or [tex]\frac{6}{-3}[/tex], or [tex]\frac{2}{-1}[/tex], or simply -2. So our slope is -2.
We can use our y-intercept (which is (0,10), as mentioned in the attached graph and table) to make the equation, in slope-intercept form, [tex]y=-2x+10[/tex] This can answer both question 5 and 5b. Remember that slope-intercept form is written using the format y=mx+b, where x any given x-coordinate, y is the corresponding y-coordinate, m is the slope and b is the y-intercept.
To put this equation in point-slope form, one must first remember that point-slope form is written in the format [tex]y-y_{1} = m(x-x_{1})[/tex], using the coordinates of any given coordinates on the same line, except for the y intercept. m also represents slope in this equation. So for this one, we can easily use (2,6). we can plug in these coordinates to get the equation y-2=-2(x-6).
Hope this helps.

I was at the store, and saw two sizes of avocados being sold. The smaller size sold for $0.92 each. For what prices would the larger avocado be a better deal?
Answer:
Large avocados should cost $ 1.83 or less to be a good deal.
Step-by-step explanation:
Since there are two types of avocado in the store, some small at $ 0.92 and others larger, to determine at what price large avocados would be a good deal, an equivalence must be established in this regard:
Thus, if two small avocados are equal to one large, buying two small avocados at $ 0.92 the total price would be $ 1.84. Therefore, any large avocado that sells for less than $ 1.84 would be a good deal. Thus, large avocados should cost $ 1.83 or less to be a good deal.

If the sides of a triangle have the following lengths, find a range possible values for x
CD = x-4, DE = 3x + 21, CE = 6x - 13
Answer:
9.5 < x < 15
Step-by-step explanation:
The possible values of x for the given problem lies in (-infinity, -1.33) ∪ (9.5, 15).
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
Given that,
The sides of the triangle are as follows,
CD = x - 4, DE = 3x + 21 and CE = 6x - 13.
There can be three cases for the given problem.
Case 1,
The longest side of the triangle is CE = 6x - 13.
Since the sum of the two sides of a triangle is always greater than the longest one, the following inequality can be written for the given triangle,
6x - 13 < x - 4 + 3x + 21
=> 6x - 13 < 4x + 17
=> 6x - 4x < 17 + 13
=> 2x < 30
=> x < 15
Case 2,
The longest side of the triangle is DE = 3x + 21.
Since the sum of the two sides of a triangle is always greater than the longest one, the following inequality can be written for the given triangle,
3x + 21 < 6x - 13 + x - 4
=> 3x + 21 < 7x - 17
=> 7x - 3x > 21 + 17
=> x > 38/4
=> x > 9.5
Case 3,
The longest side of the triangle is CD = x - 4.
Since the sum of the two sides of a triangle is always greater than the longest one, the following inequality can be written for the given triangle,
x - 4 < 3x + 21 + 6x - 13
=> x - 4 < 9x + 8
=> x - 9x > 8 + 4
=> x < -1.33
Thus, the range of the values of x is intersection of x < 15, x > 9.5 and x < -1.33, which is equivalent to (-infinity, -1.33) ∪ (9.5, 15).
Hence, the range of possible values of x lies in the interval (-infinity, -1.33) ∪ (9.5, 15).

In a sale, all normal prices are reduced by 15%
The normal price of a mixer is reduced by 22.50 dollars.
Work out the normal price of the mixer.
Answer:
The normal price of mixer is $150.
Step-by-step explanation:
Given that:
Normal prices are reduced by 15% in sale.
The normal price of mixer is reduced by $22.50
It means that it is the amount of discount.
Let,
x be the normal price of the mixer.
15% of x = 22.50
[tex]\frac{15}{100}x=22.50\\0.15x=22.50[/tex]
Dividing both sides by 0.15
[tex]\frac{0.15x}{0.15}=\frac{22.50}{0.15}\\x=150[/tex]
Hence,
The normal price of mixer is $150.
The normal price of the mixer is $150.
Given that,
In a sale, all normal prices are reduced by 15% The normal price of a mixer is reduced by 22.50 dollars.Based on the above information, the calculation is as follows;
Let us assume the normal price be x
15%x = 22.50
0.15x = 22.50
x = $150
