A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answers
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.

Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answers
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)

What are the coordinates of the vertices of the triangle under the translation (x, y) (x + 2, y + 3)? (-4, 5), (3, 4), (0, 0) (5, -4). (4, 3), (-1, 2) (6, -5), (5, 2), (1, -1) (-5, 6), (2, 5), (-1, 1)
Answers
Answer:
(2, 5), (-5, 6) and (-1, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point A(x,y) is translated a units right and b units up, the new location is at A'(x + a, y + b).
From the image attached, the location of the vertices of the triangle is at (0,2), (-7, 3) and (-3, -2). If the triangle is under the translation (x, y) ⇒ (x + 2, y + 3), the new location of the vertices would be at (2, 5), (-5, 6) and (-1, 1)
A high school track team's long jump record is 24 ft 9 1/4 in. This year, Arthur's best long jump is 24 ft 3 1/2 If long jumps are measured to the nearest quarter inch, how much farther must jump to break the record?
Answers
Answer:
5 3/4 inches
Step-by-step explanation:
Given that :
Long jump record held = 24 ft 9 1/4 in
Arthur's best long jump record = 24 ft 3 1/2 in
How much further must ARTHUR jump to brake the record :
Long jump record - Arthur's best jump
[24 ft 9 1/4 in] - [24 ft 3 1/2 in]
24 ft - 24 ft = 0
9 1/4 in - 3 1/2 in
37 / 4 in - 7 /2 in
L. C. M of 4 and 2 = 4
(37 - 14) / 4 inches
23 /4 inches

A bottle is filled with 635 g of olive oil which has a density of 0.96 g/cm3. What is the volume of the olive oil ?
Answers
Answer:
The volume of the olive oil is 661.4583 cm³
Step-by-step explanation:
The rule of the density of an object is d = M ÷ V, where
M is the mass of the objectV is the volume of the object∵ A bottle is filled with 635 g of olive oil
∴ M = 635 g
∵ The olive oil has a density of 0.96 g/cm³
∴ d = 0.96 g/cm³
→ Substitute them in the rule above
∵ 0.96 = 653 ÷ V
→ Multiply both sides by V
∴ 0.96 V = 635
→ Divide both sides by 0.96
∴ V = 661.4583 cm³
∴ The volume of the olive oil is 661.4583 cm³

Answers
Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)
= 4.86 + 0.91
= $5.77
He spent $5.77 on both items
