Answer:
5,600
Step-by-step explanation:
rounding by the nearest hundred would mean rounding up or down in the hundreds based off of thr tens. If the tens are above 50, you round up. if they are below 50, you round down
Answer:
The hundred place here is the the 2nd 5 to the left.
Rounding is when it’s 5 or above you go up, 4 or below you stay.
So 5565
In this case we look at the tenth place number which is 6 and since it’s 5 or above the hundreths place “5” goes up 1. Everything else below under th place turns 0.
So
5,600

Step-by-step explanation:
A hot-air balloon, headed due east at an average speed of 30 miles per hour at a constant altitude of 95 feet, passes over an intersection (see the figure). Find an expression for its distance d (measured in feet) from the intersection t seconds later.
Step-by-step explanation:
1 mile = 5280 ft
1 hour = 3600 seconds (60 minutes of 60 seconds each).
the open question here is : do we need the ground distance, or really the line of sight distance (e.g. directly above the intersection the distance is 0 ft ground distance but 95ft line of sight distance) ?
based on the above conversions the speed
30 miles per hour = 30×5280 ft per 3600 seconds =
= 158,400 ft / 3600 s = 44 ft/s
so, the balloon moves away from the intersection 44 ft every second.
so, just for ground distance in ft we would have
d = 44t
for the line of sight distance we need to use Pythagoras, as we need to calculate the length of the Hypotenuse (= the line of sight) of the right-angled triangle of ground distance, height and line of sight.
the ground distance is again the same function as before (44t). height is constant (95 ft).
so,
d² = (44t)² + 95² = 1936t² + 9025
d = sqrt(1936t² + 9025)
so, e.g. after 1 second the line of sight distance would be
d = sqrt(1936×1 + 9025) = sqrt(1936 + 9025) =
= sqrt(10961) = 104.6947945... ft
that means although the ground distance increased by 44 ft, the line of sight distance increased only by roughly 10 ft.
that's how right-angled triangles work.
after 2 seconds d = 129.4951737... ft, so, roughly a 25 ft increase compared to 1 second. the change rate of the line of sight distance (the Hypotenuse) will get closer and closer to the (constant) change rate of the ground distance (but will never fully reach it - only in infinity ...).

Answer:
the period of this graph is 2[tex]\pi[/tex]
Step-by-step explanation:
The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.
Let's look at the peaks (maximums).
One is at x = 0 and the next is at x = 2[tex]\pi[/tex]
2[tex]\pi[/tex] - 0 = 2[tex]\pi[/tex]
Therefore, the period of this graph is 2[tex]\pi[/tex]

I need help please. its hard..
hello againn
okay, so lets see how 32 can become 20. We can subtract 12, so that is possible. Lets check with our other inputs.
if all inputs - 12 = the output, that is the function.
14 - 12 = 2. 2 is our output, so that is a very good sign.
We cant check the third one, so lets skip that for now.
-2 - 12 = -14, which is our output. (yay!!!)
And we cant fill in the last one, which is okay.
So now we know our function is y = x - 12.
Now we fill in the question marks.
The third one. -6 + 12 = 6. The input for 3. is 6.
Last one, 10 - 12 = -22.
Function: y = x-12
Fill ins, third = 6
Last = -22.

Find the distance between the points (6, 4) and (10, 7).
Answer:
5 units
Step-by-step explanation:
Use the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2[/tex] where [tex]d[/tex] is the distance between points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
Given that [tex](x_1,y_1)\rightarrow(6,4)[/tex] and [tex](x_2,y_2)\rightarrow(10,7)[/tex], then:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(7-4)^2+(10-6)^2}\\\\d=\sqrt{3^2+4^2}\\\\d=\sqrt{9+16}\\\\d=\sqrt{25}\\\\d=5[/tex]
This means that the distance between (6,4) and (10,7) is 5 units
From the quadratic equation 3x² + X - 5 = 0, find alpha square plus beta square
Answer:
α² +β² = 3 4/9
Step-by-step explanation:
Assuming α and β are solutions to the equation, it can be factored as ...
(x -α)(x -β) = 0
Expanding this, we get ...
x² -(α +β)x +αβ = 0
Dividing the original equation by 3, we find ...
x² +(1/3)x -5/3 ≡ x² -(α+β)x +αβ ⇒ (α+β) = -1/3, αβ = -5/3
We know that the square (α+β)² can be expanded to ...
(α +β)² = α² +β² +2αβ
α² +β² = (α +β)² -2αβ . . . . . . subtract 2αβ
Substituting the values for (α+β) and αβ, we find the desired expression is ...
α² +β² = (-1/3)² -2(-5/3) = 1/9 +10/3 = 31/9
α² +β² = 3 4/9

Answer: 2295 ft ^2, 255 yd^2
Step-by-step explanation:
The area of the field is the length times the width.
Since there are 3 feet in 1 yard, 15 yards = 45 feet.
So the area in square feet = 45*51 feet^2 = 2295 ft ^2
Since there are 1/3 yard in 1 feet, 51 feet = 17 yards
So the area in square yards = 15*17 yard^2 = 255 yd^2
Find the exponential function that contains the points (2,40) and (3,8).
Answer:
Moving from point A (2,40) to point B (3,8) , you move 32 units down and one unit right, meaning your slope is 32x.
Your y-intercept is 104.
Altogether, your function (in y = mx + b format) will look like this:
y = -32x + 104
Find two numbers whose sum is 15 and difference is 3.
Answer:
The two numbers are 6 and 9
Step-by-step explanation:
Let the two numbers be x and y
x+y = 15
x-y = 3
Add the two equations together to eliminate y
x+y = 15
x-y = 3
----------------
2x = 18
Divide by 2
2x/2 = 18/2
x = 9
Now we can find y
x+y = 15
9+y = 15
y = 15-9
y = 6
The two numbers are 6 and 9

O $2,387.25
O $2,411.20
O $211.20
Answer:
$2,411.20
Step-by-step explanation:
Use the simple interest formula: A = P(1 + rt)
A = Final amount (?)
P = Starting amount (2200)
r = Rate (0.024)
t = Time in years (4)
A = 2200(1 + 0.024 · 4)
A = 2200(1.096)
A = 2411.2

Pyramid
[tex]\textsf{volume of a square based pyramid} =\frac{1}{3} a^2h[/tex]
(where [tex]a[/tex] = base edge, and [tex]h[/tex] = height)
Given:
base edge = 9 cmheight = 10cm[tex]\implies \textsf{volume} =\frac{1}{3} \times 9^2\times10=270 \ \mathsf{cm^3}[/tex]
Wax cubes
volume of a cube = w³, where w is the length of one edge
⇒ volume = 4³ = 4 x 4 x 4 = 64 cm³
Solution
To calculate how many wax cubes are needed, divide the volume of the pyramid by the volume of a wax cube:
⇒ 270 ÷ 64 = 4.21875
⇒ 5 wax cubes are needed to make the candle
We need to round this up to 5, since we need to know the number of whole wax cubes. (If we rounded down to 4, there would not be quite enough to fill the pyramid as 4 x 64 = 256 < 270)

Answer:
Step-by-step explanation:
m ∠ D + m ∠ E + m ∠ F = 180°
m ∠ D = m ∠ F - 14
m ∠ E = 2( m ∠ F ) + 10
m ∠ F - 14 + 2( m ∠ F ) + 10 + m ∠ F = 180°
4( m ∠ F ) = 180 + 4
m ∠ F = 46 °
m ∠ E = 2 × 46 + 10 = 102 °
m ∠ D = 46 - 14 = 32 °
Answer:
D = 32°
E = 102°
F = 46°
Step-by-step explanation:
The measure of angle D is 14 less than the measure of angle F
⇒ D = F - 14
The measure of angle E is 10 more than twice the measure of angle F:
⇒ E = 2F + 10
So we have now constructed two equations:
Equation 1: D = F - 14
Equation 2: E = 2F + 10
Also, we know that the sum of the interior angles of a triangle is 180°.
Therefore, D + E + F = 180
Substitute the two equations we have constructed for D and E into the sum of the interior angles equation and solve for F
D + E + F = 180
⇒ (F - 14) + (2F + 10) + F = 180
⇒ 4F - 4 = 180
⇒ 4F = 180 + 4 = 184
⇒ F = 184 ÷ 4
⇒ F = 46°
Now substitute the found value of angle F into the two equations for D and E:
D = F - 14
⇒ D = 46 - 14
⇒ D = 32°
E = 2F + 10
⇒ E = 2(46) + 10
⇒ E = 92 + 10
⇒ E = 102°
