Answer:
no
Step-by-step explanation:
The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 110 feet long. Find the period.
Answer:
11.73seconds
Step-by-step explanation:
Given the expression of length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth modeled as;
L = 0.81t²
Given
Length of the pendulum = 110feet
Required
Time (period)
Substitute the given value into the formula
L = 0.81t²
110 = 0.8t²
t² = 110/0.8
t² =137.5
t = √137.5
t = 11.73seconds
Hence the period is 11.73seconds

Can someone put this into vertex form?
y=x2+24x-15
Answer:
The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159
Step-by-step explanation:
The vertex form of the quadratic equation y = ax² + bx + c is
y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = hLet us use the facts above to solve the question
∵ y = x² + 24x - 15
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = 24
∵ h is the x-coordinate of the vertex point
∵ h = [tex]\frac{-b}{2a}[/tex]
→ Substitute the values of a and b to find h
∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]
∴ h = -12
→ To find k substitute y by k and x by h
∵ y = k and x = h
∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15
∴ k = -159
∴ The coordinates of the vertex point are (-12, -159)
→ Substitute the values of a, h, and k in the vertex form above
∵ y = 1(x - -12)² + (-159)
→ Remember (-)(-) = (+) and (+)(-) = (-)
∴ y = (x + 12)² - 159
∴ The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Answer:
84
Step-by-step explanation:
The answer is 84. Every 2cm is 24km. 6cm=72 1cm=12
9514 1404 393
Answer:
3. 84 km
4. y = 3/4x
Step-by-step explanation:
3. The map and ground distances can form a proportion:
ground distance / map distance = 24 km / (2 cm) = x / (7 cm)
Multiplying by 7 cm gives ...
x = (24 km)(7/2) = 84 km
The actual distance is 84 km.
__
4. We notice that y (9) is less than x (12), so the multiplier of x must be less than 1. The appropriate equation is ...
y = 3/4x

1) Mr. Charles bought dinner for his family.
The dinner cost $46.95.
He left a 15% tip.
About how much tip did Mr. Charles leave?
A. $1.50
B. $4.00
C. $5.00
D. $7.00
The amount of tip Mr Charles left given the total amount paid for dinner is $7
How to calculate Percentage?Total cost of dinner = $46.95Percentage of tip = 15%Amount of tip Mr Charles left = Percentage of tip × Total cost of dinner
= 15% × 46.95
= 15/100 × 46.95
= 0.15 × 46.95
= $7.0425
Approximately,
$7
Therefore, the amount of tip Mr Charles left is about $7

The Bears have won 7 and tied 2 of their last 13 games. They have not forfeited any games. Which ratio correctly compares their wins to losses?
Answer:
7:4
Step-by-step explanation:
7:4 because if 13 is the total amount of games, that minus the amount of games won and tied equals the amount of games loss which is 4. Since it says wins to losses, the wins will come first in the ratio. Therefore the correct answer would be 7:4.
Answer:
7:4

Rick invests $7,174 in an account that earns an annual interest rate of 3%. What will be the balance of the account in 18 years if the interest is compounded monthly?
A
$173,668.18
B
$7,572.00
C
$12,302.34
Answer:
A
Step-by-step explanation:
Based on the amount invested and the interest rate as well as period of compounding, the amount after 18 years will be C. $12,302.34.
As the amount is being compounded monthly, you need to convert the interest rate and the period of compounding to a monthly basis.
Interest rate = 3%/12 = 0.25%
Period = 18 x 12 months = 216 months
The amount after 18 years is:
= Amount x ( 1 + rate) ^ number of periods
= 7,174 x (1 + 0.25%) ²¹⁶
= $12,302.34
In conclusion, the amount will be $12,302.34 after 18 years.

how do you factor quadratics into binomials the question says
x^2+10x+24=x
i really don't understand that (it's 10th grade geometry)
Answer:
not factorable
Step-by-step explanation:
x^2 + 10x + 24 = x
Bring all terms to the left side and combine like terms.
Subtract x from both sides.
x^2 + 9x + 24 = 0
To factor the trinomial x^2 + 9x + 24, you need to find two integers that add to 9 and multiply to 24. Let's look at factors of 24.
24 * 1 = 24; 24 + 1 = 25
12 * 2 = 24; 12 + 2 = 14
8 * 3 = 24; 8 + 3 = 11
6 * 4 = 24; 6 + 4 = 10
There is no pair of integers whose product is 24 and whose sum is 9, so this trinomial cannot be factored.
