The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
Answer:
Step-by-step explanation:
The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
L = √d² + h²
Height is equal to [tex]14.59[/tex] feet
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle).
[tex]l=\sqrt{h^2+d^2}[/tex]
[tex]l=15[/tex] feet
[tex]d=3.5[/tex] feet
[tex]15=\sqrt{3.5^2+h^2}[/tex]
[tex]15=\sqrt{12.25+h^2}[/tex]
[tex]225=12.25+h^2[/tex]
[tex]212.75=h^2[/tex]
[tex]\sqrt{212.75}=h[/tex]
[tex]h\approx 14.59[/tex] feet

Answer:
60 degrees
Step-by-step explanation:
Using the 172 degrees and calculating it's distance from the angle, i conclude that it's 60
9514 1404 393
Answer:
(b) 60
Step-by-step explanation:
The external angle is half the difference of the two subtended arcs.
x° = (172° -52°)/2 = 120°/2
x° = 60°
The value of x is 60.
The range of y = - 32x ^ 2 + 90x + 3
Given:
The given function is:
[tex]y=-32x^2+90x+3[/tex]
To find:
The range of the given function.
Solution:
We have,
[tex]y=-32x^2+90x+3[/tex]
It is a quadratic function because the highest power of the variable x is 2.
Here, the leading coefficient is -32 which is negative. So, the graph of the given function is a downward parabola.
If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex of the quadratic function is:
[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]
In the given function, [tex]a=-32,b=90,c=3[/tex].
[tex]\dfrac{-b}{2a}=\dfrac{-90}{2(-32)}[/tex]
[tex]\dfrac{-b}{2a}=\dfrac{-90}{-64}[/tex]
[tex]\dfrac{-b}{2a}=\dfrac{45}{32}[/tex]
The value of the given function at [tex]x=\dfrac{45}{32}[/tex] is:
[tex]y=-32(\dfrac{45}{32})^2+90(\dfrac{45}{32})+3[/tex]
[tex]y=\dfrac{2121}{32}[/tex]
The vertex of the given downward parabola is [tex]\left(\dfrac{45}{32},\dfrac{2121}{32}\right)[/tex]. It means the maximum value of the function is [tex]y=\dfrac{2121}{32}[/tex]. So,
[tex]Range=\left\{y|y\leq \dfrac{2121}{32}\right\}[/tex]
[tex]Range=\left(-\infty, \dfrac{2121}{32}\right ][/tex]
Therefore, the range of the given function is [tex]\left (-\infty, \dfrac{2121}{32}\right ][/tex].
if you subtract 12 from my number and multiply the difference by -6 the result is -90 what is my number
Answer:
n must be 27
Step-by-step explanation:
Let this number be x. Then -6(n - 12) = -90.
Dividing both sides by -6 yields n - 12 = 15.
Add 12 to both sides.
Then n must be 27.
Check: subtract 12 from 27; this yields 15. Now multiply this result by -6. The result is -90, which was expected.
Evaluate the expression below when x = 9 and y = 12.
4(x + 6) - 3(y + 4)

FIND Y IN XYZ, help please
Given:
In triangle [tex]XYZ,m\angle X=90^\circ, m\angle Y=45^\circ, m\angle Z=45^\circ, XZ=y,YZ=15\sqrt{2}[/tex].
To find:
The value of y.
Solution:
In a right angle triangle,
[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
Using the above ratio for the triangle XYZ, we get
[tex]\sin Y =\dfrac{XZ}{YZ}[/tex]
[tex]\sin 45^\circ =\dfrac{y}{15\sqrt{2}}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{y}{15\sqrt{2}}[/tex]
[tex]\dfrac{15\sqrt{2}}{\sqrt{2}}=y[/tex]
[tex]15=y[/tex]

Leon has $77,343 in a savings account that earns 9% annually.The interestis not compounded.To the nearest cent,how much interest will he earnin 4 months?
Answer:
$ 2320.3
Step-by-step explanation:
Leon has $77,343 in a savings account that earns 9% annually.The interestis not compounded.To the nearest cent,how much interest will he earnin 4 months?
Since the interest is not Compounded
We solve using Simple Interest formula
= P × R × T
P = $77,343
R = 9 %
T = 4 months
Converting to years
= 4/12 = 0.3333333333
Interest = $77,343 × 9% × 0.3333333333
=$2320.29
Approximately to the nearest cents = $2320.3
