The function H(t) = -16t^2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second projectile object moves in the air along a lath represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds.
Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)
Part B: Explain what the solution from part A means in context of the problem. (4 points)
Answer:
t H(t) g(t)

Lamar has a bag of beads. He gives 20 beads to his sister. Then he makes 4 identical necklaces with the remaining beads. Write an expression that represents the number of beads on each necklace.
Answer:
x/4 - 5
Step-by-step explanation:
Let :
Number of beads in bag = x
Number of beads left = x - 20
Identical beads made from remaining = 4
Number of beads on each necklace :
Number of beads left / number of beads made
= (x - 20) / 4
= x/4 - 5

y = x2 – 24
y = x - 12
Answer:
x = -3, 4
y = -15, 8
Step-by-step explanation:
[tex]x-12=x^2-24\\0 = x^2 -x - 12\\(x +3)(x-4)=0\\x = -3,4[/tex]
[tex]y=(-3)^2-24\\y = 9-24\\y = -15\\or\\y = 4^2 - 24\\y = 16-24\\y=8[/tex]
susan ran 2.75 miles in 1/4 of an hour how fast was she traveling
Answer:
Step-by-step explanation:
ran 2 3/4 miles in 1/3 of an hour
2 3/4 miles =11/4 miles in 1/3 of hour
11/4 miles divided by 1/3 hr
11/4 ÷ 1/3
11/4 * 3/1 =33/4 =8 1/4 miles in 1 hr

Over a 24 hour period the temperature in a town can be modeled by one period of a sinusoidal function. The temperature measures 70*F in the morning, rises to a high of 80*F, falls to a low of 60*F, and then rises to 70*F by the next morning.
What is the equation for the sine function f(x), where x represents time on hours since the beginning of the 24 hour period that models the situation
Answer:

Theo has 3 sweets and 2 white sweets he picks a sweets at random write down the probability that theo picks a red sweet
Answer:
the probability is 3 ÷ 5
Step-by-step explanation:
The computation of the probability is given below:
= number of red sweets ÷ total number of sweets
= 3 sweets ÷ (3 red sweets + 2 white sweets
= 3 sweets ÷ 5 sweets
= 3 ÷ 5
Hence, the probability is 3 ÷ 5

Answer:
5 7/20 + 4 1/2 + 6 3/4 + 3 1/4 + 7 =
5 + 4 + 6 + 3 + 7 = 25
7/20 + 1/2 + 3/4 + 1/4 = 7/20 + 10/20 + 15/20 + 5/20 = 37/20 = 1 17/20
25 + 1 17/20 =

cómo puedo allar el valor absoluto de -4
Answer:
4
Step-by-step explanation:
abs(-4)=4
Answer:
Si recuerda, el valor absoluto de un número es el número "hecho positivo" al eliminar el signo menos si el número es negativo y simplemente dejar pasar el número si es positivo. Entonces, por ejemplo, el valor absoluto de -3 es 3 y el valor absoluto de 3 es 3.

Ivan biked 4 2 3 hours on Monday, 1 1 3 hour on Tuesday, and 2 2 3 hours on Wednesday. What is the total number of hours Ivan spent biking? Enter the correct answer to complete the statement. Express your answer as a mixed number with a fractional part less than 1. Choose the number of hours Ivan spent biking.
Answer: 8 2/3 hours
Step-by-step explanation:
From the question, Ivan biked 4 2/3 hours on Monday, 1 1/3 hour on Tuesday, and 2 2/3 hours on Wednesday.
The total number of hours Ivan spent biking will be:
= 4 2/3 + 1 1/3 + 2 2/3
= 8 2/3 hours
Therefore, the total hours spent biking is 8 2/3 hours
You deposit $500 in a savings account that earns 2.5% interest compounded yearly what is the balance in the account after 20 years
Answer:
the balance in the account after 20 years is $819
Step-by-step explanation:
The computation of the balance in the account after 20 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $500 × (1 + 2.5%)^20
= $500 × 1.025^20
= $819
Hence, the balance in the account after 20 years is $819

Cuál es la expresión algebraica que determina la sucesión anterior 10,17 ,24
Answer:
no se si lo necesitas en español
Step-by-step explanation:
Al darse cuenta de que
10
=
7
(
1
)
+
3
,
17
=
7
(
2
)
+
3
etc.
Una secuencia aritmética es aquella en la que alguna diferencia constante entre los números en una secuencia le da un patrón para llegar al siguiente número no listado en la secuencia.
En este caso, la diferencia es
7
. Cuando uno trabaja al revés y resta
7
desde
10
, el resultado es
3
. En el
0
a término, asumimos que
norte
>
0
para series y secuencias.
Asi que,
3
es el
0
th término, dándonos la intersección con el eje y, por así decirlo. Ahora simplemente tendríamos que reconocer que si incrementamos
norte
integralmente, y tenemos una diferencia de
7
de término a término, esa es la operación
7
norte
.
Entonces, la secuencia aritmética se generaría como:
a
0
=
3
+
7
(
0
)
=
3
a
1
=
a
0
+

a

(

a
0
+
7
(

7
(

a

7
(

=
a
1

7
(

7
(

=
a
0
+
7
(
1
)
+
7
(
1
)
+
7
(
1
)
=
24
etcétera. Cada término tiene
a
0
dentro de él, agregado a
7
veces el índice actual indicado por
a
norte
. Entonces, solo tenemos la definición recursiva:
a
norte
=
a
norte
-
1
+
7
o la definición general:
a
norte
=
3
+
7
