a car drives 52 km at a speed of 13km/h. how long does the journey take

We can solve for an acute angle in a right triangle if we know the other two angles. In the given hypothetical example, we assumed one angle was 30 degrees and the other was 90 (a right angle). We then subtracted these angles from 180 (the sum of all angles in a triangle) to find the acute angle NPO.

To solve for the acute angle NPO, we would typically need more specific information about the properties of the figure in question. However, let's suppose that triangle NPO is a right triangle and one of the given angles is 30 degrees. In this case, we can use the knowledge that the sum of all angles in a triangle equals 180 degrees.

Therefore, we set up an equation: 30 (degree of the given angle) + 90 (degree of the right angle) + X (angle NPO to be found) = 180. Solving for X gives us that NPO = 180 - 30 - 90 = 60 degrees.

Please remember that solving for an acute angle typically requires specific information about the figure and not all problems are as simple as this example demonstrates.

A linear pair involves adjacent angles formed when two lines intersect. In this context, <NPO is 40°, and <SPR is 50°, adhering to the linear pair property.

A linear pair is formed when two lines intersect at a single point, creating two adjacent angles. If these angles align in a straight line, they constitute a linear pair, and the sum of their measures is always 180°. These angles are often termed supplementary or additional angles.

In the given scenario, angle <QPO is provided as 140°. According to the linear pair property, the angle <NPO supplementary to <QPO forms a straight line, and their sum equals 180°. Therefore, <NPO is calculated as 180° - 140°, resulting in <NPO being 40 degrees.

Moving on to the second part, three angles <SPN, <SPR, and <RPQ are considered. Applying the linear pair property, the sum of these angles is 180°. Given that <SPN is 90° and <RPQ is already known as 140°, the calculation involves finding <SPR. Thus, 90° + <SPR + 40° equals 180°. Solving for <SPR, it is determined to be 50 degrees.

In summary, for the provided angles:

a) <NPO is found to be 40 degrees.

b) <SPR is determined as 50 degrees through the linear pair property.

The question probable may be:

7.What is the measure of Angle NPO?

8.What is the measure of Angle SPR if the measure of Angle RPQ is 40°?

Answer:

246.61 feet (rounded to 2 decimal places)

Step-by-step explanation:

We multiply 3/4 with previous minute traveling.

Minute #1: travels 75 feet

Minute #2: travels (3/4)*75 = 56.25 ft

Minute #3: travels (3/4)(56.25) = 42.19 ft

Minute #4: travels (3/4)(42.1875) = 31.64 ft

Minute #5: travels (3/4)(31.64) = 23.73 ft

Minute #6: travels (3/4)(23.73) = 17.80 ft

So, in 6 minutes, the car travels  75 + 56.25 + 42.19 + 31.64 +23.73 + 17.80 = 246.61 feet.

The given sequence in the question is 93, 27, 14. The solution to this sequence isn't immediately clear, as a standard mathematical pattern - such as addition, subtraction, multiplication, or division - doesn't seem to apply across all elements. Unfortunately, without additional context or a defined pattern to follow, it's not possible to definitively determine the next number in the sequence. Sequences can follow a vast array of potential patterns, including (but not limited to) geometric sequences, arithmetic sequences, quadratic sequences, or even patterns that incorporate elements of probability, set theory, or number theory.

For example, if we were looking for a simple arithmetic pattern in the given sequence, an initial glance might suggest that we are subtracting 66 and then 13 to find the second and third terms respectively. However, continuing this pattern does not result in a logical (-1) for the 'fourth' term in the sequence.

The sequence could also potentially be following a more intricate pattern - it could be geometric (each term multiplied or divided by a consistent number), quadratic (based on square or cube numbers), or even something more complex.

Step-by-step explanation:

Add them together to get rid of the y.

-6x = -4 - y

-7x = -22 + y

=

-13x = -26

Then solve for x.

-13x/-13 = -26/-13

x = 2

Now plug in the x value into either equation and solve for y.

-7(2) = -22 + y

-14 = -22 + y

-14 + 22 = -22 + 22 + y

8 = y

So...

x = 2

y = 8

Answer:

The solution is (-2, -16).

Step-by-step explanation:

-6x = -4-y  can be solved for y:  y = 6x - 4

-7x = -22 + y

In the second equation, substitute 6x - 4 for y:

-7x = -22 + 6x - 4

Grouping like terms:  0 = -22 + 6x + 7x - 4, or

                                   -26  = 13x

So x = -2.  If x = -2, we can obtain the value of y from y = 6x - 4 (see above).

y = 6(-2) - 4 = -16

The solution is (-2, -16).

EXPLANATION

The given trigonometric equation is

[tex]4 \sin ^{2} x - 4 \sin(x) + 1 = 0[/tex]

This is a quadratic equation in sinx.

We split the middle term to obtain,

[tex]4 \sin ^{2} x - 2 \sin(x) - 2 \sin(x) + 1 = 0[/tex]

Factor by grouping to get,

[tex]2 \sin(x) (2 \sin(x) - 1) - 1(2 \sin(x) - 1) = 0[/tex]

This implies that,

[tex](2 \sin(x) - 1)(2 \sin(x) - 1) = 0[/tex]

[tex] \sin(x) = 0.5[/tex]

This gives us,

[tex]x = \frac{\pi}{6} [/tex]

in the first quadrant.

Or

[tex]x = \pi - \frac{\pi}{6} [/tex]

Answer:

x = [tex]\frac{\pi}{6}[/tex], [tex]\frac{7\pi}{6}[/tex],  [tex]\frac{11\pi}{6}[/tex].

Step-by-step explanation:

The given equation is 4 sin²x - 4 sin x + 1 = 0

(2sinx)² - 2(2sinx) + 1 = 0

(2sinx - 1 )² = 0

Sinx = [tex]\frac{1}{2}[/tex] ⇒ x = sin⁻¹ ( [tex]\frac{1}{2}[/tex])

So between the interval [0, 2π] value of x will be  [tex]\frac{\pi}{6}[/tex],  [tex]\frac{7\pi}{6}[/tex],  [tex]\frac{11\pi}{6}[/tex]

[Since sine is positive in 1st 3rd and 4th quadrant]

Find the slope of the line:

Using the slope formula, we have:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the points:

[tex](2,4)\\(-4,-1)[/tex]

So, substituting we have:

[tex]m=\frac{(-1)-(4)}{-4-2}[/tex]

[tex]m=\frac{-5}{-6}[/tex]

[tex]m=\frac{5}{6}[/tex]

Find the "b" value:

Now that we know the value of the slope, we can write the equation of the line:

[tex]y=\frac{5}{6}x+b[/tex]

In order to find "b" we need to substituite any of the given points, we know that line is thru both of the given points, so, substituting (2,4) we have:

[tex]4=\frac{5}{6}*2+b\\\\4=\frac{10}{6}+b\\\\4=\frac{5}{3}+b\\\\b=4-\frac{5}{3}=\frac{(3*4)-5}3}=\frac{12-5}{3}=\frac{7}{3}[/tex]

Now that we know the slope and "b", we can write the equation of the line in slope-intercept form:

[tex]y=\frac{5}{6}x+\frac{7}{3}[/tex]

I believe it is C, there is a geometric law that states that the opposite angles across a line with both going into parallel lines will be the same angle. Rather confusing but a video online would likely explain it better than anyone could here.

Answer:

Option C. 0.5

Step-by-step explanation:

In the given diagram, AB is parallel to DE, and line AE is the transverse.

So ∠DEF ≅ ∠FAB [ Alternate angles ]

and ∠EFD ≅ AFB ≅ 90° [ Vertically opposite angles ]

So, Third angle of the triangles will also be equal.

Since angles DEF and FAB are equal so their sine values will also be equal.

Therefore, sinA = sinE = 0.5

The required fraction 40/32 simplifies to 5/4.

To simplify the fraction 40/32, we can find the greatest common divisor (GCD) of the numerator and denominator and divide both by it.

The prime factorization of 40 is 2³ * 5, and the prime factorization of 32 is 2⁵. The common factors between 40 and 32 are 2³, so the GCD is 2³ = 8.

Dividing both the numerator and denominator by 8, we get:

40/32 = (40 ÷ 8) / (32 ÷ 8) = 5/4

Kyle was 1 minute and 47 seconds faster in a 3-mile race yesterday compared to his normal running time.

Kyle's normal time is 23 minutes and 25 seconds, which is (23 * 60) + 25 = 1405 seconds. Yesterday, Kyle's time was 21 minutes and 38 seconds, which is (21 * 60) + 38 = 1298 seconds.

Now, we subtract the faster time from the normal time: 1405 seconds - 1298 seconds = 107 seconds.

Thus, Kyle was 107 seconds faster yesterday than his normal time. To put it back into minutes and seconds, we divide by 60:  107  \ 60 = 1 minute and 47 seconds.

So, Kyle was 1 minute and 47 seconds faster yesterday.

A quadrilateral with one pair of parallel sides is a trapezoid

A quadrilateral with only one pair of parallel sides can be classified as a trapezoid, which is a distinct type of four-sided figure unlike rectangles or squares.

The quadrilateral Lily designed, with only one pair of parallel sides, can be classified as a trapezoid. In geometry, this kind of shape is distinct from others we learn about in elementary levels, such as squares and triangles. A trapezoid is a four-sided figure, which makes it a type of quadrilateral but not all sides are parallel like in a rectangle or a square.

The defining feature of a trapezoid is that it has at least one set of parallel sides, known as the bases, while the other sides, which are not parallel, are referred to as the legs. Because it only has one pair of parallel sides, it differs from other quadrilaterals like rectangles, squares, and parallelograms, which have two pairs of parallel sides. The non-parallel sides of a trapezoid can be of different lengths and angles to each other, which can make trapezoids quite diverse in shape and size.

Or

[tex]( - \infty , - 7) \cup( - 7 , 0) \cup(0 , 7 )\cup(7 , + \infty )[/tex]

The domain of the function h=9x/x(x^2-49) is x = -7, x = 7.

The domain of the function h = 9x/(x(x^{2}-49)) can be determined by considering the values of x that make the denominator non-zero. Since division by zero is undefined, we need to find the values that would make the denominator equal to zero. In this case, the denominator is x(x^{2}-49), which factorizes to x(x+7)(x-7). So, the values of x that make the denominator equal to zero are x=0, x=-7, and x=7.

However, we also need to consider that the function is undefined when cancelling out those values of x that would also make the numerator zero. In this case, x=0 would make the numerator zero, so it cannot be a part of the domain.

Therefore, the domain of the function h = 9x/(x(x^{2}-49)) is given by x = -7, x = 7.
