Answer:

y=x+2

Step-by-step explanation:

the standard form is y=mx+b where m is the slope and b is the y intercept

TO FIND THE SLOPE: we take the x and y intercepts as a fraction. in this case the line touches the y axis (vertical) at point/value 2 and the x axis at point 2 as well. This means the slope is 2/2x which can be simplified to 1x or just x.

TO FIND THE Y INTERCEPT: we find where the line touches the y axis at point 2.

the slope is plugged into the m of the equation and the y intercept is plugged into the b of the equation.

Answer:

A = 51°   b = 15.3858...   c = 24.448

Step-by-step explanation:

Given: B= 39°

a = 19

and that it's a right triangle

so that means the other 3rd angle is

A+39+90=180

A= 51°

use SOH CAH TOA to remember how sin cos and tan fit on the triangle

Sin(x)=Opp/Hyp    Cos(x)=Adj/Hyp  Tan(x)=Opp/Adj

Let's use  Tan to find b

Tan(b) = Opp / Adj

Tan(39) = b / 19

19*Tan(39) = b

15.38589... = b

use Pythagoras to find c

c = [tex]\sqrt{a^{2} +b^{2} }[/tex]

c = [tex]\sqrt{19^{2} +15.3858^{2} }[/tex]

c = 24.448....

Answer:

28 units

Step-by-step explanation:

Since the perimeter of both triangles is same,

the sum of all sides of first triangle = sum of all sides of second triangle

or, 6x + 3 + 2x + 4x = 5x + 5x + 3x + 2

or, 12x + 4 = 13x + 2

or, 4-2 = 13x - 12x

or, 2 = x

Now,

Putting the value of x in the perimeter of first triangle,

12x + 4= 12* 2+ 4

= 28 units

Answer: 24 servings

Step-by-step explanation:

First and foremost, we should note that:

4 cups = 1 quart

Therefore, 3 quarts = 3 × 4 cups = 12 cups

Since she uses 5 cups of milk to make 10 servings, it means that 1 cup of milk is used to make 2 servings. Therefore, 12 cups would be used to make:

= 12 × 2

= 24 servings.

x = -4

Answer:

Step-by-step explanation:

Equation of the quadratic function given as,

g(x) = [tex]\frac{1}{3}(x-6)^2+1[/tex]

Since, leading coefficient of the function is positive,

Parabola will open upwards.

For x- intercepts,

g(x) = 0

[tex]\frac{1}{3}(x-6)^2+1=0[/tex]

(x - 6)² = -3

(x - 6) = ±√(-3)

x = 6 ± √(-3)

Since, x is an imaginary number, this function has no x-intercepts.

Similarly, for y-intercept,

x = 0

g(0) = [tex]\frac{1}{3}(0-6)^2+1[/tex]

      = 12 + 1

      = 13

y-intercept of the function → y = 13

Vertex of the parabola → (6, 1)

For x = 12,

g(12) = [tex]\frac{1}{3}(12-6)^2+1[/tex]

        = 13

Therefore, one point lying on the graph will be (12, 13).

Now we can graph the quadratic function given in the question.

Answer: Scale Factor = 1/4

Step-by-step explanation:

The base of triangle X has a length of 12, and the base of triangle x' has a length of 3. Therefore, the scale factor is 1/4, because 12 x 1/4 = 3.

Answer:

Step-by-step explanation:

The line passes through points [tex](2,0)\,,\,(0,2)[/tex]

Let [tex](x_1,y_1)=(2,0)\,,\,(x_2,y_2)=(0,2)[/tex]

Equation of a line passing through points [tex](x_1,y_1)\,,\,(x_2,y_2)[/tex] is given by [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-0=\frac{2-0}{0-2}(x-2)\\y=\frac{2}{-2}(x-2)\\y=-1(x-2)\\y=-x+2[/tex]

So,

Answer:

The coordinates of Y' will be:  A'(4, -3)

Step-by-step explanation:

Triangle XYZ with vertices

We have to determine the answer for the image Y' of the point Y(-3, 4) with respect to the line mirror y=x.

We know that when P(x, y) is reflected in y = x, we get P'(y, x)

i.e.

The rule of y=x:

As we are given that Y(-3, 4), so the coordinates of Y' will be:

A(-3, 4) → A'(4, -3)

Therefore, the coordinates of Y' will be:  A'(4, -3)

Answer:

Answer:

128 and can I get brainliest

Step-by-step explanation:

180-95 = 85

85 plus 43 = 128

180 - 128 = 52

180-52 = 128

Answer:

y=128

Step-by-step explanation:

The exterior pleus interior angle makes a 180 degree

so 180-95=85

now the interior angles of a triangle add up to 180

so the in triangle

get 43+85+?=180

180-85-43=52

nowing this we need to find the exterior angle unlike the first we are given the interior not the exterior but same process goes

180-52=128

y=128

Step-by-step explanation:

Answer:

[tex]301.29\ \text{mph}[/tex]

[tex]119.5^{\circ}[/tex]

Step-by-step explanation:

[tex]v_p[/tex] = Velocity of plane = 320 mph

[tex]v_w[/tex] = Velocity of wind = 35 mph

[tex]\theta[/tex] = Angle between wind and plane directions = [tex]125^{\circ}[/tex]

From triangle law we have resultant

[tex]v_r=\sqrt{v_p^2+v_w^2+2v_pv_w\cos\theta}\\\Rightarrow v_r=\sqrt{320^2+35^2+2\times 320\times 35\cos125^{\circ}}\\\Rightarrow v_r=301.29\ \text{mph}[/tex]

Direction is given by

[tex]\phi=\tan^{-1}\dfrac{v_p\sin\theta}{v_w+v_p\cos\theta}\\\Rightarrow \phi=\tan^{-1}\dfrac{320\sin125^{\circ}}{35+320\cos125^{\circ}}\\\Rightarrow \phi=-60.46^{\circ}=180-60.46=119.5^{\circ}[/tex]

The magnitude of the plane is [tex]301.29\ \text{mph}[/tex] moving at an angle of [tex]119.5^{\circ}[/tex].

Step-by-step explanation:

We need the numbers of each before we can calculate the probability

Number of even numbers are 50

Number of odd numbers are 50

Number of perfect squares;

1 , 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 and 100

10 perfect squares

Probability of selecting even = probability of selecting odd = 50/100 = 1/2

Probability of selecting a perfect square = 10/100 = 1/10

Thus, the probability of having the draws in the other stated in the question will be;

1/2 * 1/2 * 1/10 = 1/40

Answer:

Ok? Did you finished asking the question? Just in case, that is 89/100 or 0.89

Step-by-step explanation:

Here, Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers

The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1. The probabilities of all the outcomes add up to 1.

Given that, A local school board wants to get parents to evaluate teachers. They select 100 parents and find that 89% approve of their child’s teacher, here we need to find the population, sample and parameter of interest

So, as we see,

The population is the entire group that you want to draw conclusions about.

Therefore, the population here is = All parents

The sample is the specific group that you will collect data from.

Therefore, the sample = 100

The parameter is any characteristic that can help in defining or classifying a particular system.

Therefore, the parameter = Parents’ approval of teachers

Hence, we get Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers
