Step-by-step explanation:
A toy rocket is launched from a platform 4.9 meters above the ground in such a way that its height, h (in meters) after t seconds is given by the equation H= -4.9t^2+ 33.6t+ 4.9. How long will it take for the rocket to hit the ground?A toy rocket is launched from a platform meters above the ground in such a way that its height, h (in meters) after t seconds is given by the equation . How long will it take for the rocket to hit the ground?
Answer:
So H have to equale to 0
and [tex]t> 0[/tex]
[tex]-4,9t^2+33,6t+4,9=0\\\Delta=33,6^2+4*4,9*4,9=1225\\\sqrt{\Delta }=35\\t=\frac{-33,6-35}{2*(-4,9)} =14s[/tex]
Step-by-step explanation:
The toy rocket will take a time of 6.8571 seconds to hit the ground.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given that the height of the rocket (h), in meters, in terms of time (t), in seconds, is defined by a quadratic equation.
To determine the time needed for the rocket to hit the ground, that is, a time t greater than zero such that the height is zero. Now we proceed to solve the polynomial:
- 4.9 · t² + 33.6 · t + 4.9= 0
- 4.9 · (t² - 6.8571 · t - 1) = 0
- 4.9 · (t - 6.8571 ) · (t + 6.8571 ) = 0
Hence, the toy rocket will take a time of 6.8571 seconds to hit the ground.

Kate and Nora each have a sum of money. The ratio of the amount of money Kate has to that of Nora is 3 : 5. After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9. Find the sum of money Kate had initially.
Answer:
900
Step-by-step explanation:
K N
3x 5x
3x+150:5x-150=7:9
3x+150/5x-150=7/9
9(3x+150)=7(5x-150)
27x+1350=35x-1050
27x-35x=-1050-1350
-8x=-2400
8x=2400
X=2400/8

The table represents a linear function
What is the slope of the function?
-3
-2
3
4
Answer:
3
Step-by-step explanation:
.......................
Answer:
3
Step-by-step explanation:
The formula of to calculate slope of a linear function is
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope and so lets take any two points from the table to calculate the slope. Lets take,
(0 , 4) and (1 , 7) and lets plug it in the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{7-4}{1-0}\\\\m=3[/tex]
So the slope of the function is 3
A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195, how many times did he visit the gym? Define Variable: Equation: Solve (Show all steps):
Answer:
The number of times he visited the gym is 19 times.
Step-by-step explanation:
A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195, how many times did he visit the gym? Define Variable: Equation: Solve (Show all steps):
Let the number of times he visits the gym be represented as x
A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195,
The Amount he spends = $195
= $100 + $5 × x
$195 = $100 + 5x
5x = $195 - $100
5x = $95
x = 95/5
x = 19 times
Therefore, the number of times he visited the gym is 19 times.

59 + |-11| lol pls help fast lol
Answer:
70
Step-by-step explanation:
|-11| becomes positive cuz its an absolute. so its just 50 +11
Answer:
70
Step-by-step explanation:
The absolute value (the two lines that the -11 are between) refers to a numbers distance from zero. So more or less just remove the negative sign and add like normal.
5+3w+3-w combine like terms to simplify
Answer:
8 + 2w
Step-by-step explanation:
⇒ Change all signs to addition (subtraction is the same as adding a negative):
5 + 3w + 3 + -w
⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:
5 + 3 + 3w + -w
⇒ Simplify:
8 + 2w
Answer: 8 + 2w

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

We can write the statement that f is a function from X to Y using the function notation f:X→Y.

Jakes car has 27 gallons of gas in the tank at the beginning of his road trip. Jake uses 6 gallons of gas every hour he drives.
Answer:
he could drive 4 hours
Step-by-step explanation:
Step-by-step explanation:
if he drives for 1 hour he will have 21 gallons left
2 hours = 15 gallons left
3 hours = 9 gallons left
4 hours = 3 gallons left
4.5 hours = 0 gallons left
he could drive a total of 4.5 hours before he runs out of gas
Which of the following values does not satisfy the inequality X - 7 > 12?
A 11
B 33
C 22
D 44
Answer:
We conclude that when we put x = 11, it does not satisfy the inequality.
Hence, option (A) is correct.
Step-by-step explanation:
Given the inequality
x - 7 > 12
Any value which makes the inequality FALSE would be the value that not satisfy the inequality.
Putting x = 11 in the inequality
x - 7 > 12
11 - 7 > 12
4 > 12
FALSE!
Reason: 4 can not be greater than 12
Putting x = 33 in the inequality
x - 7 > 12
33 - 7 > 12
26 > 12
TRUE!
Reason: 26 is indeed greater than 12
Putting x = 22 in the inequality
x - 7 > 12
22 - 7 > 12
15 > 12
TRUE!
Reason: 15 is indeed greater than 12
Putting x = 44 in the inequality
x - 7 > 12
44 - 7 > 12
37 > 12
TRUE!
Reason: 37 is indeed greater than 12
Therefore, we conclude that when we put x = 11, it does not satisfy the inequality.
Hence, option (A) is correct.

A triangle has a
height of 2x + 6 and a base length of x + 4.
What is the area of the triangle?
Answer: A=x^2+7x+12
Step-by-step explanation:
A=area of triangle. h=height. b=base
A=bh/2
A=(x+4)(2x+6)/2
A=(x+4)(2x/2+6/2)
A=(x+4)(x+3)
A=x*x+4x+3x+4*3
A=x^2+7x+12

Step-by-step explanation:
syukrwdgiiyredghjjrwwxvko8wasc9eyp
Answer:
92
Step-by-step explanation:
Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.
