Expresa en forma algebraica. ⦁ El cuadrado de un número aumentado en 1. ⦁ Cinco veces un número menos 8. ⦁ El número siguiente a un múltiplo de 5. ⦁ Un número impar.

Answers

Answer:

1) N^2 + 1

2) 5*N - 9

3) n*5 + 1 (con n entero)

4) n*2 + 1 (con n entero)

Step-by-step explanation:

1) El cuadrado de un número aumentado en 1.

Podemos definir a N como el número.

El cuadrado de N es:

N^2

Y a esto lo tenemos que aumentar en 1, entonces tenemos:

N^2 + 1

Esto es el cuadrado de un número aumentado en 1.

2) Cinco veces un número menos 8.

Esto es:

5*N (5 veces un número)

Y a esto le restamos 8, para obtener:

5*N - 8

3) El número siguiente a un múltiplo de 5

Un multiplo de 5 se escribe como:

n*5

Donde n es un número entero.

El numero siguiente es:

n*5 + 1

4) Un número impar.

Bien, sabemos que un número par es un multiplo de 2.

Entonces:

n*2 es un número par.

Entonces, n*2 + 1 tiene que ser un numero impar.

En este caso la expresión algebraica es:

n*2 + 1

when the 69th even natural number is subtracted from the 119th odd natural number, what is the result

Answers

69th even number is: 69*2 = 138
119th odd number is: (2*119) - 1 = 237
69th even natural number subtracted from the 119th odd natural number is:
237 - 138 = 99.

Answer:

Step-by-step explanation:

The answer is 99 since you need to double 69 and also 119 and then subtract 1 from the double of 119. Then you would subtract them to get 99.

Suppose S and T are mutually exclusive events. Find P(S or T). P(S) = 20%, P(T) = 22%

Answers

S and P are mutually exclusive events.
P ( S ) = 20% = 0.20
P ( T ) = 22 % = 0.22
The probability of mutually exclusive events:
P ( S or T ) = P ( S ) + P ( T )
P ( S or T ) = 0.20 +0.22 = 0.42
Answer: The probability of ( S or T ) is 0.42 or 42 %.

The probability of event S or event T is 42%.

What is the probability of event S or event T?

Mutually exclusive events are independent events. Independents events are events whose occurrence do not depend on each other.

The probability of event S or event T = 20 + 22 = 42%

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x), and what does it represent?A. x = 5; the diver jumps in the pool at 5 feet per second
B. x = 10; the diver jumps in the pool at 10 feet per second
C. x = 10; the diver hits the water 10 feet horizontally from the board
D. x = 5; the diver hits the water 5 feet away horizontally from the board

Answers

We will solve the equation to find a zero of f(x): $-x^(2)-5x+50=0$
The formula is: $x_(12) = \frac{-b\pm \sqrt{b^(2)-4ac } }{2a}$ where:
a=-1, b=-5, c =50 $x_(12) = (5\pm √(25+200) )/(-2)= (5\pm √(225) )/(-2)= (-10)/(-2)=5$ This is the only solution because the other is: $(5+10)/(-2)= (15)/(-2)=-7.5$ which is not possible.
Answer: D) The diver hits the water 5 feet away horizontally from the board.

A company is paying a local radio station to run its commercials. The cost for running commercials is a one-time campaign fee and also a per-second fee for the air time of each commercial. The cost can be modeled by the equation y = 250 + 100x, where x is seconds.What is the slope, and what does it represent?

250; it represents the per-second fee of air time
250; it represents the one-time campaign fee
100; it represents the one-time campaign fee
100; it represents the per-second fee of air time

Answers

250 represents the one time campaign fee because you only have to pay for it once 100 represents the cost per second
