g(x) = x4 − 4x2 + 7x − 8?
Answer:
to put in the value of any variable in this equation(for example 2 ) we will write it as
g(2) = 4(2) - 4(2)^2 + 7(2) -8
g(2) = 8 - 16 + 14 - 8
g(2) = -2

Andreas plays soccer video game he earns three stars for every goal he scores and loses 3/4 stars every time he misses the goal he scores five goals and Misses the goal four times how many stars does he have
Answer: 12 stars
Step-by-step explanation:
First find out the number of stars he gained by scoring goals:
= Number of goals scored * Stars if goal is scored
= 5 * 3
= 15 stars
Then find out the number of stars he is to lose by missing the goal:
= No. of goals missed * stars if goal missed
= 4 * 3/4 stars
= 3 stars
The total number of stars he has are:
= Stars gained - Stars lost
= 15 - 3
= 12 stars

Fiona leaves $1600 in the bank for four years. It earns compound interest of 4% each year. Calculate the total amount Fiona has in the bank at the end of the four years
Answer:
A = $1,871.77
Step-by-step explanation:
A = P(1 + r/n)nt
Where,
A = Total money in the bank
P = principal = $1,600
r = interest rate = 4% = 0.04
n = number of periods = 1 year
t = time = 4 years
A = P(1 + r/n)^nt
A = 1,600(1 + 0.04/1)^1*4
A = 1,600(1 + 0.04)^4
= 1600(1.04)^4
= 1600(1.16985856)
= 1,871.773696
Approximately,
A = $1,871.77

John had to pay a combined electric and gas bill $150. The electric portion of the bill was $90. What is the ratio of money spent on electric to that on gas?
Given:
John had to pay a combined electric and gas bill $150.
The electric portion of the bill was $90.
To find:
The ratio of money spent on electric to that on gas.
Solution:
Let x be the amount of gas bill.
The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150. So,
[tex]90+x=150[/tex]
[tex]x=150-90[/tex]
[tex]x=60[/tex]
The gas portion of the bill was $60.
The ratio of money spent on electric to that on gas is:
[tex]\text{Required Ratio}=\dfrac{\text{Electric bill}}{\text{Gas bill}}[/tex]
[tex]\text{Required Ratio}=\dfrac{90}{60}[/tex]
[tex]\text{Required Ratio}=\dfrac{3}{2}[/tex]
[tex]\text{Required Ratio}=3:2[/tex]
Therefore, the ratio of money spent on electric to that on gas is 3:2.

of 5 Sarah, Fiona and David share £40 in a ratio 3:3:2. How much money does each person get?
Answer:
15
15
10
Step-by-step explanation:
3/8 x £40 = £15 for Sarah
3/8 x £40 = £15 for Fiona
2/8 x£40 = £10 for david
Answer:
Sarah gets [tex]\frac{3}{8}[/tex] × 40 = £15
Fiona gets [tex]\frac{3}{8}[/tex] × 40 = £15
David gets [tex]\frac{2}{8}[/tex] × 40 = £10
Step-by-step explanation:
If £40 is shared between three person in the ratio of 3:3:2 then calculate the amount each person gets.
To find the amount each person gets we are goin to change the ratios of each person into fractions.
To turn to fraction add all portions in the ratio:
3 + 3 + 2 = 8 (this will be the denominator for all proportions.)
Therefore Sarah gets [tex]\frac{3}{8}[/tex], Fiona gets [tex]\frac{3}{8}[/tex] and David gets [tex]\frac{2}{8}[/tex].
Sarah gets [tex]\frac{3}{8}[/tex] × 40 = £15
Fiona gets [tex]\frac{3}{8}[/tex] × 40 = £15
David gets [tex]\frac{2}{8}[/tex] × 40 = £10

Answer:
Probability[Selected ball is a white ball without replacement (W)] = 5 / 22
Step-by-step explanation:
Given:
Number of white ball in jar = 5
Number of black ball in jar = 6
Find;
Probability[Selected ball is a white ball without replacement (W)]
Computation:
Probability of an event = Number of favorable outcomes / Total number of outcomes
Probability of 1st white ball = 5 / [5 + 6]
Probability of 1st white ball = 5 / 11
Probability of 2nd white ball [without replacement] = 5 / [11 - 1]
Probability of 2nd white ball [without replacement] = 5 / 10
Probability[Selected ball is a white ball without replacement (W)] = [5/11][5/10]
Probability[Selected ball is a white ball without replacement (W)] = 25 / 110
Probability[Selected ball is a white ball without replacement (W)] = 5 / 22

Find x
To do this, we make use of:
[tex]x + 23^o + 2x + 4^o = 180^o[/tex] --- angle on a straight line
Collect like terms
[tex]x + 2x = 180^o - 4^o - 23^o[/tex]

Is it 81x^2 sq cm ?
Or 18x^2 sq cm
Or 81x sq cm
Or 18x sq cm
Answer:
81x^2 sq cm
Step-by-step explanation:
Area formula: length × width
Squares are the same size on all 4 sides, which means because 1 side is 9x cm, all other sides will also be 9x cm.
Area: 9x cm × 9x cm = 81x^2 cm^2
sq = ^2

Hola, alguien me puede resolver esta operación? a. Múltiplo de 5 y de 6 mayor que 95.000 ( _ 8 9 1 _ ) b. Divisible por 3, 4 y 5, menor que 4.675. ( 4 6 _ _ )
Answer:
a) 98,910
b) 4,620
Step-by-step explanation:
Recordar que un numero N es multiplo de A si N es divisible por A.
Entonces, decir:
Buscar N, tal que sea multiplo de A
es lo mismo que decir:
Buscar N, tal que sea divisible por A.
a) Queremos un múltiplo de 5 y de 6 mayor que 95.000
( _ 8 9 1 _ )
Sabemos que los múltiplos de 5 terminan en 0 o 5.
Y un número de 5 dígitos mayor que 95,000 requiere que el quinto digito en este caso sea 9, entonces tendremos:
98,91_
Para encontrar el dígito de las unidades, podemos probar remplazarlo por 0 y por 5, y luego dividirlo por 6.
Si el resultado es un número entero, entonces el número será un múltiplo de 6.
Probemos con 0, vamos a tener el número:
98,910
dividiéndolo por 6 obtenemos:
98,910/6 = 16,485
Entonces:
98,910 es más grande que 95,000
es múltiplo de 5 (porque termina en cero)
Y es múltiplo de 6, como acabamos de comprobar.
b) Ahora queremos un número divisible por 3, 4 y 5, que sea menor que 4,675
4,6__
De vuelta, como tiene que ser divisible por 5, sabemos que termina en 5 o 0.
Y como también tiene que ser divisible por 4, sabemos que tiene que terminar si o si en número par, entonces podemos concluir que solo puede terminar en 0.
Así, sabemos que el número va a ser algo como:
4,6_0
Ahora podemos probar con el dígito de las decenas, de tal forma que el número sea divisible por 3, 4 y 5.
Recordar que este número tiene que ser menor que 4,675
Entonces el número faltante puede ser:
0, 1, 2, 3, 4, 5, 6, 7
Ahora también podemos recordar que un número es solo divisible por 3 si la suma de todos sus dígitos es divisible por 3.
Entonces tenemos que tener que:
4 + 6 + x + 0 = múltiplo de 3
10 + x = múltiplo de 3
Los posibles valores de x van a ser:
x = 2 (porque 12 es múltiplo de 3)
x = 5 (porque 15 es múltiplo de 3)
Ok, ahora sabemos que el número restante solo puede ser 2 o 3.
Entonces tenemos que remplazar esos valores en el número y ver si este es divisible por 4 o no.
Comenzamos con el 2.
Tendremos el número:
4,620
Probamos dividiendo esto por 4:
4,620/4 = 1,155
El resultado es entero, entonces 4,620 es divisible por 4 (y por como lo creamos, también sabemos que es divisible por 3 y por 5, y además es menor que 4,675, como queríamos)
