Show similarity between triangle WXZ and triangle VXY then write XY/XZ=VY/WZ
The reason is: The ratio of corresponding sides of similar triangle are equal.
David must install fencing around a lot that is shaped like a right triangle. The side of the lot that runs east-west is 200 ft long. The side of the lot that runs north-south is 125 ft long. Calculate how many feet of fencing he will need to surround the entire lot. If necessary, round your answer to the nearest whole.
1. Observe problem
I think 200ft and 125 ft are both sides, so:
sqrt(200^2+125^2) is 25sqrt{89}
which is
235.84952

If a sprinkler waters 1/15 of a lawn in 1/3 hour, how much time will it take to water the entire lawn?
Answer:
ok so first we know that 1/3 of a hour is 20 minutes since
60*1/3=20
so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15
20*15=300
300 minutes or 5 hours
Hope This Helps!!!
Answer:
5 Hour
Step-by-step explanation:
For 1/15 of lawn it takes = 1/3
So, for entire lawn it will take = 1/3 * 15 = 5

===========================================
Work Shown:
AC/QS = BC/RS
4/10 = m/15
4*15 = 10*m
60 = 10m
10m = 60
m = 60/10
m = 6
The first equation is possible because the triangles are similar. The horizontal sides AC and QS form the ratio AC/QS. This is equal to the ratio of the diagonal sides BC/RS since similar triangles have their sides in proportion.
After the equation is set up, we cross multiply and then solve for m.

Given the perimeter of a square is (8x-6). What is the area,in cm², of the square ?
Answer:
16x² - 24x + 9
Step-by-step explanation:
One side = (8x-6)÷4
One side = 2x - 3/2
Area = (2x-3/2)(2x-3/2)
Open the brackets
2x(2x-3/2) - 3/2(2x-3/2)
= 16x² - 24x + 9

Use given triangle to fill in the blank.
Answer:
[tex]\sin B=\displaystyle\frac{b}{c}[/tex]
Step-by-step explanation:
Hi there!
This is the sine ratio:
[tex]\sin\theta=\displaystyle\frac{opposite}{hypotenuse}[/tex] where "opposite" is the side opposite the angle, "hypotenuse" is the hypotenuse of the right triangle and theta is the angle.
To find sin B, we must identify which sides of the triangle are the opposite side and the hypotenuse.
The side opposite to angle B would be b.
The hypotenuse is the side opposite the right angle, and that would be c.
[tex]\sin B=\displaystyle\frac{b}{c}[/tex]
I hope this helps!
Answer:
The choice second

Answer: 6
Step-by-step explanation:
Since the 3 semicircles are identical, we know that each semicircle has a diameter of 4, meaning they each have a radius of 2.
We can use the fact that (arc length of semicircle) = (pi)(r) to get the arc length of each to be 2pi.
Meaning 2pi + 2pi + 2pi = 6pi.

Answer: 12
Step-by-step explanation:
Distribute the 9(x-11) first. If you distribute it, it becomes 9x-99
9x-99=9
Add 99 to both sides
9x=108
Divide by 9 on both sides

6/11 = c/77 solve the proportion
Hey there!
6/11 = c/11
6(77) = c(11)
6(77) = 11(c)
462 = 11c
We got the new equation above because we had to CROSS MULTIPLY.
11c = 462
DIVIDE 11 to BOTH SIDES
11c/11 = 462/11
CANCEL out: 6/6 because it give you 1
KEEP: 462/11 because it help solve for the c-value
NEW EQUATION: c = 462/11
SIMPLIFY IT!
c = 42
Therefore, your answer is: c = 42

Help Solve please and explain find X and Y
Answer:
y = [tex]\frac{9}{2}[/tex][tex]\sqrt{2}[/tex]
x = 9
Step-by-step explanation:
this triangle is isosceles because the base angles are each 45°
the ratio of sides in a 45-45-90° triangle are 1 : 1 : [tex]\sqrt{2}[/tex]
so 'y' is going to also be [tex]\frac{9}{2}[/tex][tex]\sqrt{2}[/tex]
'x' will be [tex]\sqrt{2}[/tex] multiplied by [tex]\frac{9}{2}[/tex][tex]\sqrt{2}[/tex] which will be:
[tex]\frac{(9x2)}{2}[/tex] = 9
what is the vertex of the graph of the quadratic function f(x)= x^{2} + 6x + 10?
Answer:
vertex = (- 3, 1 )
Step-by-step explanation:
given a quadratic in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
f(x) = x² + 6x + 10 ← is in standard form
with a = 1, b = 6 , then
x = - [tex]\frac{6}{2}[/tex] = - 3
substitute x = - 3 into f(x) for corresponding y- coordinate
f(- 3) = (- 3)² + 6(- 3) + 10 = 9 - 18 + 10 = 1
vertex = (- 3, 1 )

What is an expοnential functiοn?An expοnential functiοn is a mathematical functiοn οf the fοrm f(x) = a^x, where a is a cοnstant and x is the variable. The cοnstant a is called the base οf the expοnential functiοn, and it is typically a pοsitive real number. When a is greater than 1, the functiοn represents expοnential grοwth, while when a is between 0 and 1, the functiοn represents expοnential decay.
Expοnential functiοns have sοme special prοperties, such as the fact that the rate οf change οf the functiοn is prοpοrtiοnal tο its value. In οther wοrds, the larger the value οf the functiοn, the faster it grοws οr decays. Expοnential functiοns alsο have a hοrizοntal asymptοte at y = 0 when a is between 0 and 1, and nο hοrizοntal asymptοte when a is greater than 1.
Expοnential functiοns are widely used in mathematics, science, ecοnοmics, and engineering tο mοdel phenοmena that exhibit expοnential grοwth οr decay, such as pοpulatiοn grοwth, radiοactive decay, and cοmpοund interest. They are alsο used in prοbability theοry tο mοdel the distributiοn οf randοm variables, such as the expοnential distributiοn.
Tο cοmplete the equatiοn fοr h(x), we need tο find the values οf a and b in the expοnential functiοn that cοrrespοnd tο the given table οf values:
x | h(x)
0 | 10
1 | 10
2 | 10
3 | 4
4 | 4
5 | 4
Since the value of h(x) is constant (equal to 10) for x = 0, 1, and 2, we know that [tex]b^0 = b^1 = b^2 = 1[/tex], which implies that b = 1.
Substituting b = 1 into the exponential function, we have:
[tex]h(x) = a * 1^x = a[/tex]
To find the value of a, we can use any of the given values of h(x) for which x > 2. For example, when x = 3, we have:
h(3) = 4 = a
Therefore, the complete equation for h(x) is:
[tex]h(x) = 4 * 1^x = 4[/tex]
