Answer:

mAngle1 + mAngle2 = 180°

Step-by-step explanation:

Knowing that:

Supplementary angles are 180 degree

Solve:

The only one with 180 is the third one.

Thus, the answer is mAngle1 + mAngle2 = 180°

Answer:

Slope = -2/1 = -2

Step-by-step explanation:

You can look at the points on the image and see the "directions" to get from one point to the next: you go down 2 and over 1. This is -2/1, which is -2.

You could also pick and two points and do a calculation. It can be any two points on the line and it will come out the same.

For example (-1,3) and (0,1) are two points on the line. To find slope, subtract the y's and put that on top of a fraction, then subtract x's and put that on the bottom.

3 - 1 goes on top.

-1 - 0 goes below.

3-1 / -1 - 0

2/-1

= -2

Slope = -2

Answer:

[tex]x=\frac{3\pi n}{5}[/tex]

Step-by-step explanation:

We know that [tex]cot(\frac{5x}{3})=\frac{cos(\frac{5x}{3})}{sin(\frac{5x}{3})}[/tex], so [tex]cot(\frac{5x}{3})[/tex] is undefined where [tex]sin(\frac{5x}{3})=0[/tex]:

[tex]sin(\frac{5x}{3})=0\\\\\frac{5x}{3}=\pi n\\\\5x=3\pi n\\\\x=\frac{3\pi n}{5}[/tex]

So, the discontinuities for the function [tex]f(x)=cot(\frac{5x}{3})[/tex] are where [tex]x=\frac{3\pi n}{5}[/tex] with [tex]n[/tex] being any integer.

Answer: 4 roses and 8 tulips.

Step-by-step explanation: Each rose costs $5, so she bought 4 of them, which is $20 so far.  Since she already bought 4 roses, she bought twice that amount for tulips, which is 8.  Each tulip costs $2, so that's $16.  Add both $20 and $16 and you have $36.

Hope this helps! :)

The function of the amount of money is an illustration of an exponential function

The initial balance of the investment is $700, and the rate is 83.53%

The function of the amount of money in the investment is given as:

[tex]A(t) = 700(0.8353)^t[/tex]

The above function is an exponential function, and an exponential function is represented as:

[tex]A(t) = ab^t[/tex]

Where:

a represents the initial value, and b represents the rate.

By comparison, we have:

a = 700

b = 0.8353 = 83.53%

Hence, the initial balance of the investment is $700, and the rate is 83.53%

Answer:

  A: the triangles are similar

  B: AB corresponds to QR

  C: ∠PAB corresponds to angle Q

Step-by-step explanation:

A line segment parallel to the base of a triangle will create a similar triangle. The AA similarity postulate can be used to conclude that.

__

The triangles PQR and PAB are similar. This derives from the fact that angle P is in both triangles, and corresponding angles PAB and PQR are congruent. The AA congruence postulate applies.

__

Based on the similarity statement, segment AB corresponds to segment QR.

__

Transversal PQ crosses parallel lines AB and QR at points A and Q, respectively. The corresponding angles are PAB and PQR.

Step-by-step explanation:

We must do the first derivative test. Here is the steps:

Step 1: Differentiate the polynomial once

we get

[tex]2 {x}^{2} - 2x - 112[/tex]

Step 2: Set this equal to zero and solve for x.

[tex]2 {x}^{2} - 2x - 112 = 0[/tex]

[tex] {x}^{2} - x - 56 = 0[/tex]

[tex](x - 8)(x + 7) = 0[/tex]

[tex]x = 8[/tex]

[tex]x = - 7[/tex]

The solutions are your critical points.

So our critical points are (8,-7).

Step 3: Plot -7 and 8 on a number line. First, pick a number lesser than -7 and plug plug in the derivative function.

Let use -10.

[tex]( - 10 - 8)( - 10 + 7) = 54[/tex]

Since that number is positive, this means are increasing when (-oo,-7)

Next, pick a number greater than 8. Let use 9.

[tex](9 - 8)(9 + 7) = 16[/tex]

Since that is positive, the interval is increasing whe (8,oo)

C. If we pick a number in between -7 and 8, we will get a negative number which means the function is decreasing on interval (-7,8)

Answer:

222 yd²

Step-by-step explanation:

Bottom and top area, each = 7 * 3 = 21 yd²

Two lateral surdaces, each = 7 * 9 = 63 yd²

Two lateral surdaces, each = 3 * 9 = 27 yd²

Total area = 2 x (21 + 63 + 27) = 222 yd²

Step-by-step explanation:

Realizando un corte en cada esquina del cubo como se muestra en la imagen quedarían una figura de 13 caras.

Para saber el número de caras resultante de cortar todas las puntas del cubo debemos tener en cuenta que el cubo tiene 6 caras y 8 puntas.

De acuerdo a lo anterior, debemos remplazar cada punta por una cara, debido a que cada punta va a quedar como una cara luego del corte, es decir que tendríamos que sumar 6 caras y 8 caras producto del corte de las puntas.

6 + 8 = 13

Entonces, el número de caras de esta figura sería 13.

Answer:

Z = x - µ / ∂

  = 24.2 – 24.6 / 0.07

   =-0.4/ 0.07

  = -5.71

Step-by-step explanation:

Solution:

Mean = µ = 24.4mm

Standard deviation = ∂= 0.07 mm

(a) Diameter less than 24.3 mm

P(x < 24.3)

The formula for normalized z value:

Z = x - µ / ∂

  = 24.3 - 24.4 / 0.07

  = - 0.1 / 0.07

 = -1.4286

P(z  < -1.428) = 1 – p ( z > -1.428)

                       = 1 – p( z < 1.42)

                         =1 – 0.4233

                         = 0.5767

(b) Diameter greater than 24.6 mm

P( x > 24.6)

The formula for normalized z value:

Z = x - µ / ∂

  = 24.3 – 24.6 / 0.07

   =-0.3 / 0.07

   = - 4.285

P( z > -4.285) = 1 – p(z < -4.285)

                        = 1 – p ( z > 4.285)

                        =

(c) Diameter between 24.2 and 24.5 mm.

P(x > 24.5)

Z = x - µ / ∂

  = 24.5 – 24.6 / 0.07

   =-0.1/ 0.07

   = -1.4286

P(z  < -1.428) = 1 – p ( z > -1.428)

                       = 1 – p( z < 1.42)

                         =1 – 0.4233

                         = 0.5767

P(x < 24.2)

Z = x - µ / ∂

  = 24.2 – 24.6 / 0.07

   =-0.4/ 0.07

   = -5.71
