Step-by-step explanation:

16.95+9x=25.50+5x

16.95+4x=25.50

4x=8.55

x=2.13

Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).

So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, [tex]\vec{v}[/tex], has been shown in the figure.

The magnitude of the vector:

[tex]|\vec{v}|=\sqrt{(1-0)^2+(-2-0)^2}=\sqrt{1+4}=\sqrt{5}[/tex]

The direction of a vector is the angle made by a vector with the positive direction of the x-axis.

From the figure, [tex]\theta = 180 \degree\tan ^{-1} \left|\frac {0-(-2)}{0-1}\right|[/tex]

[tex]\theta = 180 ^{\circ} - \tan^{-1}(2) = 180 ^{\circ} - 63.43^{\circ}[/tex]

[tex]\theta =116.57 ^{\circ}[/tex]

Hence, the required vector having a magnitude [tex]\sqrt {5}[/tex] and direction [tex]116.57 ^{\circ}[/tex] has been shown in the figure.

Answer:

x = 11, ∠ 2 = 146°

Step-by-step explanation:

∠ 2 and 146° are corresponding angles and are congruent, then

∠ 2 = 146°

Thus

13x + 3 = 146 ( subtract 3 from both sides )

13x = 143 ( divide both sides by 13 )

x = 11

Answer:

The slope is 2

Step-by-step explanation:

Pick two points and plug into this equation: y2-y1/x2-x1

(-3,2) and (-1,6)

2-6/-3-(-1)=-4/-2= 2

Answer:

The slope of the linear function is 2

Step-by-step explanation:

Calculating the Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

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

The table shows four points: (-3,2), (-1,6), (1,10), and (3,14). To find the slope on the line passing through them we only need two, for example (-3,2), (-1,6):

[tex]\displaystyle m=\frac{6-2}{-1+3}[/tex]

[tex]\displaystyle m=\frac{4}{2}=2[/tex]

Any other pair of points should give the very same value for the slope. Use (1,10), and (3,14):

[tex]\displaystyle m=\frac{14-10}{3-1}[/tex]

[tex]\displaystyle m=\frac{4}{2}=2[/tex]

Thus, the slope of the linear function is 2

Answer:

By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Step-by-step explanation:

We need to explain why the function of [tex]f(x)=4x^2+8x[/tex] is neither even or odd

First we will understand, when the function is even and odd

Even function:

A function is even if f(-x) = f(x)

Odd function:

A function is odd if f(-x) = -f(x)

So, if we get the above result by putting x = -x, then we can say that the function is even or odd.

If we don't get any of the above results then the function is neither even nor odd.

So, for the given function: [tex]f(x)=4x^2+8x[/tex]

Put x = -x

[tex]f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x[/tex]

So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Answer:

-1 4/5, -1.7, -1 1/10, -1.

Step-by-step explanation:

We convert all of these to tenths. -1 4/5 becomes - 1 8/10. -1.7 becomes -1 7/10. -1 1/10 is already in tenths and -1 is a whole number. When putting these from least to greatest, remember that the bigger the negative, the less the number is.

10 x a = 10a

answer = 10a

Step-by-step explanation:

the answer on top is step by step

ax2x5

    ^   ^

      10xa

The way I learned it was that if they dont have the same variables dont touch them, so what I did was multiply the like numbers (2 and 5). Why are they alike? Because they don't have a variable! I then just put the X sign there to show that there is no other way to multiply this. If it where addition, it would be 10+a so that would equal 10a.

Answer:

So draw a straight line. This measures as 180 degrees on your protractor. Align your protractor to the straight line, with the circle point in the middle of the line and notice the labels on the side. One of them, between 90 and 180 on the outer scale will measure as 135. Mark this on top of the paper, and remove the protractor. When you remove it, extend your mark to the middle of your line, and this gives you an obtuse angle of 135 degrees. Be sure to recheck!

Answer:

x ≈ 31.0°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanx = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{15}[/tex], then

x = [tex]tan^{-1}[/tex] ([tex]\frac{9}{15}[/tex] ) ≈ 31.0° ( to 1 dec. place )

Step-by-step explanation:

Answer:

521 feet.

Step-by-step explanation:

In the given question, the number of feet covered with respect to climbing would have a positive value. While the number of feet descended would have negative value.

The total feet covered by Brody and Carrie, with the elevation of the trail-head should be equal to the elevation of their destination above sea level.

To determine the elevation of the trail-head, let its elevation be represented by h.

So that,

h + 103 - 84 + 194 = 734

h + 297 - 84 = 734

h + 213 = 734

h = 734 - 213

h = 521

h = 521 feet

The elevation of the tail-head is 521 feet.

2. It can't be an obtuse triangle: 5² + 7² = 74 < 10²

   the triangle is an obtuse-angled triangle if  the square of the longest side (c²) is greater than the sum of the square of other two sides (c²>a²+b²)

Answer:

0.625

Step-by-step explanation:

Given the points :

(0, 4) and (-8, -1)

x1 = 0 ; y1 = 4

x2 = - 8 ; y2 = - 1

Slope, m = rise / run

Rise = y2 - y1 = - 1 - 4 = - 5

Rise = x2 - x1 = - 8 - 0 = - 8

The slope, m = - 5 / - 8

Slope, m = 0.625
