Answer:
p(x): y-intercept is 4; the base is 3; the equation is p(x) = 4(3^x)
q(x): y-intercept is 4; the base is 2; the equation is p(x) = 4(2^x)
Step-by-step explanation:
The y-intercept of both graphs is 4
The standard exponential function equation is
y = ab^x
We need to find a and b for each function.
For each graph, we use two points to find a and b in the standard exponential function equation.
p(x)
y = ab^x
Use point (0, 4)
4 = ab^0
4 = a * 1
a = 4
y = 4(b^x)
Use point (1, 12)
12 = 4(b^1)
b = 12/4
b = 3
The base is 3.
p(x) = 4(3^x)
q(x)
y = ab^x
Use point (0, 4)
4 = ab^0
4 = a * 1
a = 4
y = 4(b^x)
Use point (1, 8)
8 = 4(b^1)
b = 8/4
b = 2
The base is 2.
q(x) = 4(2^x)

Porfavor: Elabora un problema matemático relacionado con tu vida cotidiana donde utilices “adición y sustracción de números con signo” y el resultado sea - 9
Answer:
Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.
El caso más simple para este tipo de problemas es algo como:
"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"
Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)
Entonces el vuelto va a ser:
vuelto = $C - ($A + $B)
Y queremos que el resultado de este problema sea 9, entonces podemos escribir:
vuelto = $9 = $C - ($A + $B)
Ahora debemos encontrar los valores de las incógnitas.
Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:
$9 = $20 - ($2 + $B)
$9 = $20 - $2 -$B
$9 = $18 - $B
$9 - $18 = -$B
-$9 = -$B
Entonces $B será = $9.
Y el problema podría escribirse como:
"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"
What is the value of 1/2+(-5/6)+1/4
Answer:
B. -1/12
Step-by-step explanation:
1/2 - 5/6 + 1/4 = -1/12
[tex] \frac{1}{2} - \frac{5}{6} = \frac{3}{6} - \frac{5}{6} = - \frac{2}{6} \\ \\ = - \frac{1}{3} + \frac{1}{4} = - \frac{4}{12} + \frac{3}{12} = - \frac{1}{12} [/tex]

I NEED HELP!!! ASAP!!!
Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.
Is this wrong if so plssss give me the answer
Answer:
30 not -30 x

tenths where necessary.
Answer:
It's quite simple and there is no need for rounding, the answer should be 8ft
Step-by-step explanation:
Here's why,
This problem can be solved with the Pythagorean Theorem, since in draws a triangle.
The picture should explain it, let's double check:
6^2+8^2=10^2
36+64=100
Looks like it checks out
Answer:
I agree, the answer should be 8ft

Answer:
50 min
Step-by-step explanation:
Convert the hours and minutes to pure minutes. 1hr40min =60min +40min= 100min and 2.5hrs =2(60min)+30min=150min. Then subtract 150 from 100 to get 50 min longer.

A luxury chairs manager found that an employee made 3/4 of a chair every 3/8 of an hour
How many chairs does the employee make per hour?
Answer:
Step-by-step explanation:
(3c/4)/(3h/8)
(3c/4)(8/3h)
(24/12)c/h
2 c/h
So employee can make 2 chairs in one hour.
What is the difference between solving this equation: x - 4 = 17 AND this equation : 5x - 1 = 24 ?
Answer: See explanation
Step-by-step explanation:
x - 4 = 17
Collect like terms to get the value of x
x = 17 + 4
x = 21
5x - 1 = 24
Collect like terms to get the value of x
5x = 24 + 1
5x = 25
Divide both side by 5
5x/5 = 25/5
x = 25/5
x = 5
A ship sails 30km from A on a bearing of 048 degrees and a further 42km on a bearing of 110 degrees to arrive at B. What is the distance and bearing B from A.
Answer:
The distance from A to B is approximately 67.5 km
The bearing of B from A is approximately 86.89°
Step-by-step explanation:
i) The distances and the bearing of the motion of the ship is given as follows;
The distance the ship sails on a bearing of 048° = 30 km
The distance further the ship sails on a bearing of 110° = 42 km
From the drawing of the sailing of the ship created with Microsoft Visio, we have;
∠C = 48° + 70° = 118°
By cosine rule, we have;
c² = b² + a² - 2·b·a·cos(∠C)
From which we have;
c² = 30² + 48² - 2 × 30 × 48 × cos(118°) ≈ 4,556.07810082
c ≈ √(4,556.07810082) ≈ 67.5
The distance from A to B = c ≈ 67.5 km
ii) By sine rule, we have;
a/sin(A) = b/sin(B) = c/sin(C)
∴ sin(A) = a·sin(C)/c
Substituting the values of the variables gives;
sin(A) ≈ 48·sin(118°)/67.5
∠A ≈ arcsin(48·sin(118°)/67.5) ≈ 38.89°
Therefore, the bearing of B from A ≈ 48 + 38.89 = 86.89°.
How do you find the original price if the percent of discount is 25% in the sales price is $40
25% — $40
100% — $40 * 4 = $160
The original price is $160.
