Given:
The function is
[tex]h=3+25t-5t^2[/tex]
To find:
The values of t where h is 8 meters.
Solution:
We have,
[tex]h=3+25t-5t^2[/tex]
Putting h=8, we get
[tex]8=3+25t-5t^2[/tex]
[tex]0=3+25t-5t^2-8[/tex]
[tex]0=-5+25t-5t^2[/tex]
[tex]0=-5(1-5t+t^2)[/tex]
Dividing both sides by -5 and interchanging the sides, we get
[tex]1-5t+t^2=0[/tex]
[tex]t^2-5t+1=0[/tex]
Here, [tex]a=1,b=-5,c=1[/tex].
Using quadratic formula, we get
[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]t=\dfrac{-(-5)\pm \sqrt{(-5)^2-4(1)(1)}}{2(1)}[/tex]
[tex]t=\dfrac{5\pm \sqrt{25-4}}{2}[/tex]
[tex]t=\dfrac{5\pm \sqrt{21}}{2}[/tex]
It can be written as
[tex]t=\dfrac{5-\sqrt{21}}{2}[/tex] and [tex]t=\dfrac{5+\sqrt{21}}{2}[/tex]
[tex]t=0.20871215[/tex] and [tex]t=4.7912878[/tex]
[tex]t\approx 0.21[/tex] and [tex]t\approx 4.79[/tex]
Therefore, the required values of t are 0.21 and 4.79.

Q1. Prasha has five blocks of wood. The total weight of all five blocks of wood is 3 kilograms. 4 of the blocks of wood each have a weight of 650 grams. Work out the weight, in grams, of the other block of wood.
Answers
Answer: Weight of the remaining block of wood =400g
Step-by-step explanation:
Total Weight of five(5) blocks = 3kg = 3000g
Weight of 4 out of the 5 blocks = 650x 4= 2600g
Weight of the remaining block of wood =Total Weight of five(5) blocks-Weight of 4 out of the 5 blocks
= 3000g-2600g
=400g

The Pizza Barn sells one customer 3 large pepperoni pizzas and 2 orders of breadsticks for $30. They sell another customer 4 large pepperoni pizzas and 3 orders of breadsticks for $41. How much does the Pizza Barn charge for each pepperoni pizza and each order of breadsticks
Answers
Answer:
Pizzas: $8, Breadsticks: $3
Step-by-step explanation:
1. Write an equation.
Let the variables p = price of pizzas, and b = price of breadsticks
The equation: 3p + 2b = $30 for the first customer. The equation: 4p + 3b = $41 for the other customer.
2. Use the Elimination Method.
(4p+3b=41) x3 = 12p+9b=123
- (3p+2b=30) x4 = 12p+8b = 120
------------------------------------------------
8b = 3
Pizzas: $8
Breadsticks: $3

Step-by-step explanation:
by using Pythagorean theorem we can find the 3rd side;
(5/13)^2 + (12/12)^2 = 169 / 169 = 1
the root of number one is also 1.
Use the Pythagorean theorem to solve
(12/13)^2 + (5/13)^2 = x^2
(114/169) + (25/169) = x^2
169/169 = x^2
1 = x^2
1 = x

Describe how your figure would translate given the rule. (x + 5, y - 3)
Answers
Answer: Translate 5 units to the right, 3 units down
=============================================================
Explanation:
The x+5 means we add 5 to each x coordinate. A point like (1,2) moves to (6,2) after adding on 5 to that coordinate. This visually means the point moves 5 units to the right.
The y-3 means we shift 3 units down because we subtract 3 from the y coordinate. So for example, the point (6,2) moves to (6,-1).
Overall, the rule [tex](x,y) \to (x+5, y-3)[/tex] means a point like (1,2) will move 5 units to the right and 3 units down to arrive at (6, -1). I recommend you try out more examples.

Como calcula-se a àrea de um cubo
Answers
Answer:
Spanish:
En palabras, el área de la superficie de un cubo es el área de los seis cuadrados que lo cubren. El área de uno de ellos es un * a, o un 2. Como todos son iguales, puedes multiplicar uno de ellos por seis, por lo que el área de la superficie de un cubo es 6 veces uno de los lados al cuadrado.
Además, un cubo tiene 6 caras. El área de cada cara se encuentra elevando al cuadrado la longitud del lado. Multiplica el área de una cara por el número de caras para obtener la superficie total del cubo.
Step-by-step explanation:
English:
In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
Also, A cube has 6 faces. The area of each face is found by squaring the length of the side. Multiply the area of one face by the number of faces to get the total surface area of the cube.

The American Quarter Horse is the most popular riding horse in the world. The average weight of an American Quarter Horse at birth is 85 pounds. They grow to a maximum weight of 1300 pounds. Write and solve an inequality to find how many pounds an American Quarter Horse may gain from birth to adulthood.
Answers
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the average weight of an American Quarter Horse at birth is 85 pounds and that they grow to a maximum weight of 1300 pounds.
The inequality to calculate the amount of pounds that an American Quarter Horse may gain from birth to adulthood will be the difference between it's maximum weight and weight at birth. This will be:
= 1300 - 85.
= 1215 pounds
