Answer:

The slope is -4.

Step-by-step explanation:

The formula to find slope is y2 - y1 / x2 - x1

Step 1: 9-1 / 6 - 8

Step 2: 8/-2

Step 3: Simplify: The slope is -4

Hope this helps!

Answer:

1) False

2) True

3) a) True b) False

4) False

Step-by-step explanation:

1)

Two-point are collinear if they lie in the same line. The vector -2AB is antiparallel to the vector AB then it is False.

2)

A unit vector could be difinede as:

[tex]\vec{u}=\frac{\vec{v}}{|\vec{v}|}[/tex]

Terefore, [tex]\frac{1}{AB}\vec{AB}[/tex] is a unit vector. It is True.

3)    

a) If AB=-3AC

The points, A, B, and C are collinear, because all of them lie in the same line. True

b) Let's take the modulus in each side.

[tex]\vec{AB}=-3\vec{AC}[/tex]

[tex]|\vec{AB}|=|-3\vec{AC}|[/tex]

[tex]|\vec{AB}|=|-3||\vec{AC}|[/tex]

[tex]|\vec{AB}|=3|\vec{AC}|[/tex]

So it is False.

4)

If we put the vector AI = 3/2 AB into the first equation we will have:

[tex]2(-\frac{3}{2}\vec{AB})+3\vec{IB}=-3\vec{AB}+3\vec{IB}[/tex]

And we can not say that it is a cero vector, so it is False.

I hope it helps you!

Answer:

20.83 yard

Step-by-step explanation:

Calculate Cubic Yards

Calculate your area

Calculate your volume: Multiply area times the depth to get volume in cubic feet

Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer

Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard

Total yards = 5[x] + x + 8

Solve

133 = 6x + 8

6x = 125

x = 20.83 yard

Therefore, the Cyclone cleared 20.83 yards on the first day.

The pitcher can throw 58 until he reaches the limit, hopefully I helped :)

Answer:

Indirect variation

Rule: [tex]y = \frac{18}{x}[/tex]

Step-by-step explanation:

Given

[tex]x \to 2,3,4,5[/tex]

[tex]y \to 9,6,4.5,3.6[/tex]

Required

Determine the type of variation

For direct variation, we have:

y increases, as x increases

In the above function, y decreases, as x increases

Hence, it is not a direct variation

Indirect variation.

In an indirect variation, y decreases, as x increases

And the equation is given as:

[tex]y = \frac{k}{x}[/tex]

Make k the subject

[tex]k =xy[/tex]

Where k is the constant of variation.

For:

[tex](x,y) = (2,9)[/tex]

[tex]k = 2 * 9 = 18[/tex]

For:

[tex](x,y) = (3,6)[/tex]

[tex]k = 3 * 6 = 18[/tex]

For every other values;

[tex]k = x * y = 18[/tex]

Hence, it is an indirect variation.

The rule is:

[tex]y = \frac{k}{x}[/tex]

Substitute 18 for k

[tex]y = \frac{18}{x}[/tex]

Answer:

y = 1.4x + 5.6

Step-by-step explanation:

plug the slope and y-intercept into the formula: y = ax + b (a is the slope and b is the y-intercept)

thus, y = 1.4x + 5.6

Answer:

Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

Step-by-step explanation:

Since Sasha's grandma is going to sew an umbrella for Sasha, which will be made of 4 identical triangles, if each triangle is 3 feet long and 4 feet high, to determine how many square feet of fabric does Sasha's grandma need, the following calculation must be done:

(3 x 4) x 4 = X

12 x 4 = X

48 = X

Therefore, Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

Answer:

Height of toy model liberty statue = 3 feet (Approx.)

Step-by-step explanation:

Given:

Height of real liberty statue = 152 feet

Scale factor = 2:101

Find:

Height of toy model liberty statue

Computation:

Scale factor = 2:101

1 feet toy model = 101 / 2 = 50.5 feet

Height of toy model liberty statue = Height of real liberty statue / Scale factor

Height of toy model liberty statue = 152 / 50.5

Height of toy model liberty statue = 3 feet (Approx.)

Based on the calculations, the measure of angle m<SB rounded to the nearest tenth is equal to 0.70°.

In geometry, a tangent is also referred to as a tangent line and it can be defined as a straight line that touches a plane curve at a specific point.

Based on the diagram, we would apply the cosine function to determine the measure of the angle formed by the hypotenuse side of the triangle with respect to the radius of Earth (adjacent side):

m<SB = cos⁻¹(4000/4000 + 0.2) + cos⁻¹(4000/4000 + 0.01)

m<SB = cos⁻¹(4000/4000.2) + cos⁻¹(4000/4000.01)

m<SB = cos⁻¹(0.99995) + cos⁻¹(0.9999975)

m<SB = 0.573 + 0.128

m<SB = 0.701 ≈ 0.70°.

To find:

The simplified value of the given expression.

Solution:

We have,

[tex]\dfrac{15m^2-3}{3m-1}[/tex]

On dividing, we get

[tex](3m-1)|\overline{15m^2+0m-3}|5m+\dfrac{5}{3}[/tex]

          [tex]-(15m^2-5m)[/tex]

              [tex]\overline{\quad \quad -5m-3}[/tex]

                    [tex]-(5m-\dfrac{5}{3})[/tex]

                       [tex]\overline{\quad \quad -\dfrac{4}{3}}[/tex]

Here, quotient is [tex]5m+\dfrac{5}{3}[/tex]  and the remainder is  [tex]-\dfrac{4}{3}[/tex].

Therefore, [tex]\dfrac{15m^2-3}{3m-1}=5m+\dfrac{5}{3}-\dfrac{4}{3(3m-1)}[/tex].
