We will use graphical method to solve it.

The inequalities are

Graph both

We can see that the solution region is rightwards

The solution is (1.2,0.8)

Option D as the intersection point is ahead 1 unlike option A

Answer:

Given system of inequalities:

[tex]\large\begin{cases}y < \frac{2}{3}x\\y\geq-x+2\end{cases}[/tex]

When graphing inequalities:

[tex]y < \dfrac{2}{3}x[/tex]

The slope of the first inequality is 2/3, therefore at x = 1, y = 2/3.

So the correct line for the first inequality is the dotted line with the shallower slope.

As the relation is < for this inequality, the shading should be below the dotted line.

[tex]y\geq-x+2[/tex]

From inspection of the given graphs, the line of the second inequality (solid line) is the same in all graphs.

As the relation is ≥ for this inequality, the shading should be above the solid line.

Therefore, the only graph that satisfies these conclusions is graph D (attached).

Step-by-step explanation:

z is the length of the midsegment of the triangle. (Given)

[tex]\implies[/tex] midsegment will be parallel to the third side of the triangle.

[tex]\implies x=31\degree[/tex] (Corresponding angles)

Answer:The correct answer is:

90 feet.

Explanation:

Each wire forms a right triangle with the tree and the ground. The height from the ground to the point on the tree the wire is attached to, 3 feet, is one leg. The length from the tree to where the wire is staked in the ground, 4 feet, is the other leg.

We use the Pythagorean theorem to find the hypotenuse: 3²+4²=c²; 9+16=c²; 25=c²; √25=√(c²); 5=c

This means each wire will be 5 feet long. There are 3 wires per tree, which gives us 5*3 = 15 feet. There are 6 tree, so this is 15*6 = 90 feet of wire.

Step-by-step explanation:

Answer:

  175°

Step-by-step explanation:

Bearing angles are usually measured clockwise from North. Reverse bearing angles differ from forward bearing angles by 180°. These relations and the usual angle sum relation for a triangle can be used to solve this problem.

Angle PQR will be the difference in the bearings from Q to P and Q to R:

  ∠PQR = 124° -46° = 78°

Triangle PQR is isosceles, so the base angle at P will be ...

  ∠QPR = (180° -78°)/2 = 51°

__

The bearing from P to R will be 51° less than the bearing from P to Q. The bearing from P to Q is 180° more than the bearing from Q to P.

  PR bearing = PQ bearing - ∠QPR

  = PQ bearing - 51°

  = (46° +180°) -51° = 175°

The bearing of R from P is 175°.

Answer:

  296.1 yards

Step-by-step explanation:

The surveyor is interested in solving a triangle with two sides and the enclosed angle known. The Law of Cosines is used for that purpose.

The angle interior to the triangle where the surveyor turned is the supplement of the turning angle:

  180° -110° = 70°

The law of cosines tells us the relation of the given sides (a, b) and angle (C) to the unknown side (c) is ...

  c² = a² +b² -2ab·cos(C)

  c² = 245² +270² -2·245·270·cos(70°) ≈ 87675.7350

  c ≈ √87675.7350 ≈ 296.10

The length of the lake is about 296.1 yards.

Step-by-step explanation:

oh, come on !

we have a point on the curve : (3, -2)

we simply put the values in and calculate the missing factor of x² :

-2 = f × 3² = f × 9

f = -2/9

y = -2/9 x² = -0.222222222... x²

When we are finding f(x) given a value of x, we must identify the value of y that results from the value of x.

We are asked to find f(2).

On the graph, first find the location of x=2.

Then, identify where the function is at x=2.

Finally, identify the corresponding y-value: 12.

The value of f(2) is 12.

Answer: 1/8

Step-by-step explanation:

(W) white (B) black (R) red (BL) blue   (BP) blue pants (TP) tan pants

                       |-------------(B)

                       |-------------(W)

(TP)------------- |-------------(R)

|                       |-------------(BL)

|                      |--------------(B)

|                      |--------------(W)

(BP)-------------|--------------(R)

                      |--------------(BL)

From the tree diagram, a white shirt with tan pants is one out of eight possible outcomes, so the probability of getting tan pants and a white shirt is 1/8.

Answer: 1 lima bean, 2 red beans, 3 black-eyed peas

Step-by-step explanation:

If 1/6 of the beans are lima beans, then there are 6 * 1/6 lima beans in the salad. 6 * 1/6 = 6/6 = 1.

If 1/3 of the beans are red beans, then there are 6 * 1/3 red beans in the salad. 6 * 1/3 = 6/3 = 2.

If 1/2 of the beans are black-eyed peas, then there are 6 * 1/2 black-eyed peas in the salad. 6 * 1/2 = 6/2 = 3.

Answer:

Lima Beans: 6 x [tex]\frac{1}{6}[/tex] = 1

Red Beans: [tex]\frac{1}{3}[/tex] x 6 = 2

Black Eyed-Peas: [tex]\frac{1}{2}[/tex] x 6 = 3

Answer:

B) B=10(2)^(t/3)

Step-by-step explanation:

The Formula used to find Exponential Growth is

[tex]y=a*b^{\frac{t}{t_{1} } }[/tex]

where y is the Final Amount

a is the Initial Amount

b is the Growth Factor

t is Time

t1 is Time to Complete one Growth

so for our Problem

a=10 and b=2 and t1=3 and y=B

so B=10(2)^(t/3)

So

The expression is

Yes, the samples are likely to be representative of all teachers and non-teachers in the state.

The median, in similarity with the mean is a statistical measure of central tendency.

Since, the double box-and-whisker plot shows the distribution of sample medians, it follows that the samples are likely to be representative of all teachers and non-teachers.
