Answer:
2,000
Step-by-step explanation:
Look at the hundreds place. It has a 5 in its place. The rule for rounding is that if the number directly to the right of the place you are rounding is 4 or below, you round down. If it's 5 or above, you round up. It has a 5 in its place, so we round up. The 5 becomes a 0, and the 1 in the thousands place becomes a 2. All other places are 0 because the rounding up affects all other places.I hope this helps!

Answer: [tex]\dfrac{\sqrt2}{2}[/tex]
Step-by-step explanation:

[tex]=\dfrac{1}{2}\cdot \dfrac{\sqrt2}{2}+\dfrac{\sqrt3}{2}\cdot\dfrac{\sqrt2}{2}\qquad =\dfrac{\sqrt2+\sqrt6}{4}[/tex]

sin75 - sin15
[tex]=\dfrac{\sqrt2+\sqrt6}{4}-\dfrac{\sqrt6-\sqrt2}{4}[/tex]

Find h(-2) if h (x) = x3 + 1
ou live in the building on the left in the drawing, and a friend lives in the other building. the two of you are having a discussion about the heights of the buildings, and your friend claims that the height of his building is more than 1.50 times the height of yours. to resolve the issue you climb to the roof of your building and estimate that your line of sight to the top edge of the other building makes an angle of 21° above the horizontal, whereas your line of sight to the base of the other building makes an angle of 52° below the horizontal. determine the ratio of the height of the taller building to the height of the shorter building. state whether your friend is right or wrong.
Answer:
1.3
Friend is wrong
Step-by-step explanation:
Given:
friend's claim: height of his building is more than 1.50 times the height of yours
line of sight to the top edge of the other building makes an angle of 21° above the horizontal
line of sight to the base of the other building makes an angle of 52° below the horizontal
Solution:
Let A be the height of your building is A
Let B+A his building is B higher than yours.
Let the distance between the buildings is x.
then
tan 52 = A/x
tan 21 = B/x
A/B = tan 52 / tan 21
= 1.27994 / 0.38386
A/B = 3.33
(A + B) / A = 1.5 0
A/A + B/A = 1.50
1 + B/A = 1.50
B/A is basically (B/x) / (A/x)
So
1+ 3.33 / 3.33
= 4.33/3.33
= 1.3
Since 1.3 is not equal to 1.5
Hence the friend's claim is wrong.
The height of the taller building can be given in relation to the height of
the other building using trigonometric ratios.
Correct response:
The claim is wrongReasons for the above responseThe given parameters are;
Angle of elevation to the top of the other building = 21°
Angle of depression to the base of the other building = 52°
The claim of the friend = The height of his building > 1.5 × The height of the other building
Required:
To state whether the claim is right or wrong.
Solution:
Let h represent the height of the smaller building, let l represent the
distance between the two buildings, and let d represent the height by
which one building is taller than the other, we have;
[tex]tan\left(21^{\circ} \right) = \mathbf{ \dfrac{d}{l} }[/tex]l·tan(21°) = d
[tex]tan \left(52^{\circ} \right) = \mathbf{\dfrac{h}{l} }[/tex]l·tan(52°) = h
Height of the taller building, H = h + d = l·tan(52°) + l·tan(21°)
Height of the other building = h = l·tan(52°)
Therefore;
[tex]\dfrac{H}{h} = \mathbf{ \dfrac{l \cdot tan \left(52^{\circ} \right) + l \cdot tan \left(21^{\circ} \right)}{l \cdot tan \left(52 ^{\circ} \right)}} = 1 + \dfrac{tan \left(21^{\circ} \right)}{tan \left( 52^{\circ} \right)} \approx 1.3[/tex]H ≈ 1.3·h
Which gives that the taller building, H, is approximately 1.3 times the other building.
Therefore;
The claim is incorrectLearn more about trigonometric ratios here:

AB is dilated by a scale factor of 3 to form A1B1. Point O, which lies on AB, is the center of dilation. The slope of AB is 3. The slope of A1B1 is . Through point O.
Answer:
[tex]Slope\ of\ A'B'= 3[/tex]
Step-by-step explanation:
Given
[tex]Slope\ of\ AB= 3[/tex]
Required
Determine the slope of A'B'
Represent the coordinates of AB with (x,y), such that
[tex]AB = (x,y)[/tex]
Since A'B' is 3 * AB, we have
[tex]A'B' = 3 * AB[/tex]
Substitute (x,y) for AB
[tex]A'B' = 3 * (x,y)[/tex]
[tex]A'B' = (3x,3y)[/tex]
Since the slope of AB = 3, then the slope of A'B' is also equal to 3 because dilation through (0,0) does not have effect on the slope

a gardener spends half an hour to mow and weed the lawn which has a measurement of 24 m × 15 m. He is paid $25 per hour. how much is he paid for a lawn which has a measurement of 48m × 30m?
Answer:
$100
Step-by-step explanation:
Half - a - hour = (24*15) =360 m
one hour payment $25
hour(?) =(48*30) = 1440 m
1440/ 360 = 4 hours
So, 25*4 =$100
Solise is planting 24 bushes and 16 trees in equal rows. She wants all the rows to be exactly the same with no plants left over. What is the greatest number of rows Solise can plant?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
Since Solise want to plant both trees and bushes in the same number of rows, you need to find the common factor.
Since the question is asking what the greatest number of rows she can plant, you have to find the greatest common factor.
The greatest common factor of 24 and 16 is 8.
You can plant 24 bushes in 8 rows (meaning you can divide it by 8), and 16 trees in 8 rows (meaning you can divide it by 8). Since the greatest number you can divide them both by is 8, the GCF of 24 and 16 is 8.
So the greatest number of rows Solise can plant is 8 rows.

Write the equation in standard form for the ellipse with center at the origin, vertex (-8, 0), and co-vertex (0,4).
Answer: [tex]\dfrac{x^2}{64}+\dfrac{y^2}{16}=1[/tex]
Step-by-step explanation:
The standard form for an ellipse is: [tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] where
(h, k) is the centera is the radius on the x-axisb is the radius on the y-axisGiven: (h, k) = (0, 0)
a = 8 (distance on x-axis from origin to -8)
b = 4 (distance on y-axis from origin to 4)
Input h = 0, k = 0, a = 8, b = 4 into the standard form for an ellipse:
[tex]\dfrac{(x-0)^2}{8^2}+\dfrac{(y-0)^2}{4^2}=1[/tex]
[tex]=\dfrac{x^2}{64}+\dfrac{y^2}{16}=1[/tex]

Answer:
a: [tex]40h+75f=800,h+f=13[/tex]
b: 5
c: 8
Step-by-step explanation:
Explanation for a: Making the equations
Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations [tex]40h+75f=800,h+f=13[/tex] since the total cost will be 800$, and we have a total of 13 ads.
Explanation for b: Solving for h
We can now solve for one of the variables using elimination. Let’s multiply the expression [tex]h+f=13[/tex] by -75.
[tex]-75h - 75f = -975[/tex]
Great! Now let’s add the equations.
[tex]40h + 75f = 800\\\\-75h - 75f = -975[/tex]
Adding these equations, we get
[tex]-35h = -175[/tex]
Divide both sides by -35, and we get [tex]h = 5[/tex].
Explanation for c: Solving for f
We can now substitute h inside the equation [tex]h + f = 13[/tex].
[tex]5 + f = 13\\\\f = 13-5\\\\f = 8[/tex]
Hope this helped!
(a) Let's say that h = half-page advertisement, and f = full-page advertisement.
Now It is given that there is a total of 13 advertisements present, and hence we have the first equation h + f = 13. Respectively we have the equation 40h + 75f = 800. This is represented by the following system of equations,
[tex]\begin{bmatrix}h+f=13\\ 40h+75f=800\end{bmatrix}[/tex]
(c) From here on let's solve this system for h and f. Isolating h in the first equation would give us h = 13 - f, which then can be substituted into the second equation to receive 40(13 - f) + 75f = 800. Let's solve for f --- (1)
40(13 - f) + 75f = 800,
520 - 40f + 75f = 800,
520 + 35f = 800,
35f = 280,
f = 280 / 35 = 8 full advertisements
(b) Now let's substitute this value of f back into the first equation to solve for the value of h --- (2)
h + 8 = 13,
h = 13 - 8 = 5 half advertisements

Answer:
Adult ticket= 7£
Child ticket= 2£
Step-by-step explanation:
Let the cost of an adult ticket be £A and the cost of a child ticket be £C.
2A +3C= 20 -----(1)
A +4C= 15 -----(2)
From (2):
A= 15 -4C -----(3)
Susbt. (3) into (1):
2(15 -4C) +3C= 20
30 -8C +3C= 20 (expand)
30 -5C= 20 (simplify)
5C= 30 -20
5C= 10
C= 10 ÷5
C= 2
Subst. C=2 into (3):
A= 15 -4(2)
A= 15 -8
A= 7
Thus, the cost of an adult ticket and a child ticket is 7£ and 2£ respectively.

Step-by-step explanation:
The sum to infinity of a geometric sequence is calculated as

where a is the first term and r the common ratio
Here a = 1 and r = [tex]\frac{1}{5}[/tex] , thus
[tex]S_{infinity}[/tex] = [tex]\frac{1}{1-\frac{1}{5} }[/tex] = [tex]\frac{1}{\frac{4}{5} }[/tex] = [tex]\frac{5}{4}[/tex] → D
