Answer:
1 17/24
Step-by-step explanation:
we have to make both denominators of the fractions the same. in order to do this you have to basically increase the fraction and make it 20/24. Do the same thing to 7/8 and get 21/24. Now we can add them together 20/24 + 21/24 = 41/24 = 1 17/24

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%
How to interpret the function?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%

Kelsey bought some roses and tulips.She bought twice as many tulips as roses. Roses cost $5 each. Tulips cost $2 each .Kelsey spent $36 total. How many of each kind of flower did Kelsey buy ?
Answers
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.

Find the slope of the line
Answers
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

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)

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]:

¿Cuántas caras quedan al cortar con un plano cada esquina de un cubo como se muestra en la figura?
Answers
Realizando un corte en cada esquina del cubo como se muestra en la imagen quedarían una figura de 13 caras.
Cómo calcular en número de caras de la figura?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

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.
__
Part A: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.
