Step-by-step explanation:
A ball is thrown from an intial height of 5 feet with an intial upward velocity of 17 ft/s. The ball's height h in feet after t seconds is given by the following.
h=5+17t-16t^2
Find all values of t for which the ball's height is 9 feet.
Round your answer(s) to the nearest hundredth.
Answer:
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33
==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)

Suppose you start at the origin, move along the x-axis a distance of 4 units in the positive direction, and then move downward along the z-axis a distance of 2 units. What are the coordinates of your position
Answer:
[tex]B = (x+4,y-2)[/tex]
Step-by-step explanation:
Let the current position be A:
[tex]A = (x,y)[/tex]
Required
Determine the new position
First, you move 4 units to the right.
This is represented as [tex]x + a[/tex]
Where a is the number of units to the right
In this case:
[tex]a = 4[/tex]
So, we have: [tex]x + 4[/tex]
Then you move 2 units downwards
This is represented as [tex]y - b[/tex]
Where b is the number of units downwards.
In this case:
[tex]b = 2[/tex]
So, we have: [tex]y - 2[/tex]
So, the new position (B) is:
[tex]B = (x+4,y-2)[/tex]

Option D: 5√5 is the correct answer.
Step-by-step explanation:
Given that:
√20 + √45
These can also be written in simplified form;
√5*4 + √5*9
We will take square root of 4 and 9.
The square root of 4 and 9 is,
√4 = 2
√9 = 3
Thus,
2√5 + 3√5
Adding the roots,
5√5
Hence,
Option D: 5√5 is the correct answer.

4.8 + 2.2w − 1.4w + 2.4
Answer:
7.2 + 0.8w
Step-by-step explanation:
combine like terms. Like terms have same variable with same power.
2.2w and (-1.4w) are like terms & 4.8 and 2.4 are like terms.
4.8 + 2.2w - 1.4w + 2.4 = 4.8 + 2.4 + 2.2w - 1.4w
= 7.2 + 0.8w
Answer:
7.2+0.8w
Step-by-step explanation:
4.8+2.2w-1.4w+2.4
4.8+2.4=7.2 2.2w-1.4w=0.8w
What is the value of z?
Answer:
68°
Step-by-step explanation:
Every figure must sum 180°(Sides-2) degrees
Example: For a triangle (3 sides) 180°(3-2) => 180°(1) =>180°
In this case: 5 sides 180°(5-2) => 540°
So all the angles (5) must sum 540°
Mathematically expressed as:
[tex](119)+(z)+(2z)+(70)+(2z)+(11)=540\\119+z+2z+70+2z+11=540\\200+5z=540\\5z=540-200\\5z=340\\z=\frac{340}{5}\\z=68'[/tex]
Lets see changing every Z by 68...
119+68+2(68)+70+2(68)+11
119+68+136+70+136+11=540°

the average motorcycle weighs 32,000 grams. How many kilograms does the average motorcycle weigh?
Answer:
The average motorcycle would weigh 32 kilograms.
Step-by-step explanation:
1 kilogram = 1000 grams
so, to find how many kilograms a motorcycle is, we just need to divide the amount of grams by 1000
32,000 / 1000 = 32 kg
Xavier start 5 feet away from the motion detector. He then walks away from the detector at a rate of 0.5 ft./s for four seconds. He remains still for two seconds, and then walks towards the motion detector at a rate of -2 ft./s for three seconds. How far in feet Xavier from the motion detector when he finishes his walk?
Answer:
1 ft away from the motion detector.
Step-by-step explanation:
To calculate Xavier's distance we can assume that the motion detector would be represented as 0ft. Now we simply need to create the arithmetic expression for every step/action that Xavier performed. Finally, we would solve the expression to calculate Xavier's total distance from the motion detector.
5ft + (0.5ft * 4) + (-2ft * 3)
5ft + 2ft - 6ft
1ft
Finally, we can see that Xavier is 1 ft away from the motion detector.

Acellus Solve for c. 9 - V[?] C = Enter the number that goes beneath the radical symbol. 7 C 7 9 Enter i need help can you break it down for me
Answer:
[tex]c=\sqrt{130}\\[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\7^2+9^2=c^2\\49+81=c^2\\130=c^2\\\sqrt{c^2}=\sqrt{130}\\c=\sqrt{130}[/tex]
So c would equal whatever the square root of 130 is.
If x = 9, what is the value
of 7x + 4?
Answer:
67
Step-by-step explanation:
7x9=63
63+4=67
Answer:
67
Step-by-step explanation:
If x = 9, our new equation is:
7 x 9 + 4
We use PEMDAS to get:
7 x 9 = 63
63 + 4 = 67
So 63 is your answer

A random sample of 27 fields of rye has a mean yield of 43.1 bushels per acre and standard deviation of 5.31 bushels per acre. Determine the 80% confidence interval for the true mean yield. Assume the population is approximately normal. Step 2 of 2 : Construct the 80% confidence interval. Round your answer to one decimal place.
Answer:
The 80% confidence interval = (41.8, 44.4)
Step-by-step explanation:
From the above question, the random number of samples is 27, this sample size is below 30, hence it is small.
To solve for this, we have use t score instead of confidence interval.
Degrees of freedom = 27 - 1 = 26
t score for 80% confidence interval = 1.315
The 80% confidence interval = Mean ± t score × standard deviation/√n
Mean = 43.1 bushels
Standard deviation = 5.31
Hence,
43.1 ± 1.315 × 5.31/√27
43.1 ± 1.3438116191
Hence:
43.1 - 1.3438116191
= 41.756188381
≈ 41.8
43.1 + 1.3438116191
= 44.443811619
Approximately ≈ 44.4
Therefore, the 80% confidence interval = (41.8, 44.4)
