Sarah has saved $150. She wants to double the amount she saves each month. As an incentive, Sarah’s grandma says if she saves that amount, she will give her an additional $50 each month. What are the recursive formula and first term for Sarah’s saving’s?
Answer:
A₁ = $150.
Step-by-step explanation:
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.

Un terreno tiene las siguientes dimensiones 52 m x 44 m. Una persona trota por la orilla del terreno y todos los días recorre 4.5 vueltas, partiendo de un vértice del rectángulo, si todo el recorrido lo hace en 1.47 minutos ¿Cuál es la magnitud de la velocidad (m/s) que realizó?
Podemos definir la magnitud de la velocidad como el cociente entre la distancia total recorrida y el tiempo que tomo recorrerla.
Encontraremos que la magnitud de la velocidad es 9.8 m/s.
En este caso, tenemos un terreno rectangular de 52m por 44m.
Recordamos que el perimetro de un rectangulo de largo L y ancho A está dado por:
P = 2*(L + A)
En este caso, el perimetro será:
P = 2*( 52m + 44m) = 192m
Si la persona recorre este perimetro 4.5 veces, entonces la distancia total que recorre es 192 metros por 4.5:
distancia = 4.5*192m = 864m
Y sabemos que la recorre en 1.47 minutos.
Notar que queremos la magnitud de la velocidad en metros sobre segundo, por lo que debemos reescribir este tiempo en segundos.
1 minuto = 60 segundos
Entonces:
1.47 minutos = (1.47)*60 segundos = 88.2 segundos.
Finalmente, la magnitud de la velocidad será:
V = (864m)/(88.2s) = 9.8 m/s

Using the Triangle Sum Theorem. Determine the angle measure
of <1.
38
31
(78 and 31 degrees)
Answer:
71 degrees
Step-by-step explanation:
Hi there!
The sum of the interior angles of a triangle is always 180 degrees.
Knowing this, to solve for the measure of angle 1, subtract 78 and 31 degrees from 180:
180-78-31
= 71
Therefore, angle 1 measure 71 degrees.

The width of a rectangle measures (3c-9d)(3c−9d) centimeters, and its length measures (8c-2d)(8c−2d) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
HELP
-22d + 22c
Step-by-step explanation:
The expression for the perimeter of the rectangle is 2(11c - 11d)
Perimeter of a rectangle = 2(length + width)
Length = 3c - 9d
Length = 3c - 9d Width = 8c - 2d
The expression for the perimeter can be expressed thus :
2(3c - 9d + 8c - 2d)
Collect like terms :
2(3c + 8c - 9d - 2d)
2(11c - 11d)
Hence, the expression for the perimeter of the rectangle is 2(11c - 11d)

Answer:
x = 5
Step-by-step explanation:
If the lines containing points A, B, C, D are parallel, then those two angles are equal because they would be corresponding angles. Therefore, you would set up this equation:
25x - 17 = 20x + 8
Subtract 20x from both sides
5x - 17 = 8
Add 17 to both sides
5x = 25
Divide both sides by 5
x = 5

tom is 2 kg heavier than harry, who is 3 kg heavier than ben. when they add up all their weights, it comes to 65 kg. how many kg does harry weigh?
Answer:
Step-by-step explanation:
Let Harry = x
Tom = harry + 2
Tom = x + 2
Ben + 3 = harry
harry - 3 = ben
x - 3 = ben
Tom + harry + Ben = 65
x + 2 + x + x - 3 = 65
3x - 1 = 65 Add 1 to both sides
3x = 65 + 1
3x = 66 Divide by 3
x = 66/3
x = 22
So harry = 22 kg
