Answer:
∠B
∠Y
Step-by-step explanation:
we know that
In the right triangle ABC
[tex]tan(B)=\frac{AC}{BC}[/tex] ----> opposite side to angle B divided by the adjacent side to angle B
substitute the values
[tex]tan(B)=\frac{3}{4}[/tex]
Remember that
If two triangles are similar, then the corresponding sides are proportional and the corresponding angles are congruent
so
∠A=∠W
∠B=∠Y
∠C=∠Z
therefore
[tex]tan(B)=tan(Y)[/tex]
Base on the fact that the triangle ABC and WYZ are similar, the angles whose tangent equals 3 / 4 are ∠B and ∠Y
What are similar triangles?Similar triangle are only different in sizes but are of the same shape.
Similar triangles, corresponding sides are always in the same ratio. Corresponding angles of similar triangles are always congruent. Therefore,
∠A = ∠W
∠B = ∠Y
∠C = ∠Z
Therefore, let's find all angles in the similar triangles whose tangent is equal to 3 / 4 .
tan ∅ = opposite / adjacent
Since,
tan B = 3 / 4
Then
tan Y = 3 / 4
Therefore,
The angles whose tangent equals 3 / 4 are ∠B and ∠Y

Find the product of 1 3/5 and 8 (show work please tysm)
Answer:
20 4/5
Step-by-step explanation
13/5 x 8/1 = 104/5= 20 4/5
The product of [tex]\(1 \frac{3}{5}\)[/tex] and [tex]\(8\)[/tex] is calculated by first converting the mixed number to an improper fraction and then multiplying the two fractions together.
Step 1: Convert [tex]\(1 \frac{3}{5}\)[/tex] to an improper fraction.
To convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fractional part and add the numerator of the fractional part. Then, place the result over the original denominator.
For [tex]\(1 \frac{3}{5}\)[/tex] , the whole number is [tex]\(1\)[/tex], and the fractional part is [tex]\(\frac{3}{5}\)[/tex]. So, we have:
[tex]\[ 1 \times 5 + 3 = 5 + 3 = 8 \][/tex]
Thus, [tex]\(1 \frac{3}{5}\)[/tex] as an improper fraction is [tex]\(\frac{8}{5}\)[/tex].
Step 2: Multiply the improper fraction by \(8\).
Now, we multiply [tex]\(\frac{8}{5}\)[/tex] by [tex]\(8\)[/tex] . When multiplying fractions, we multiply the numerators together and the denominators together:
[tex]\[ \frac{8}{5} \times 8 = \frac{8 \times 8}{5} \][/tex]
Step 3: Simplify the product.
[tex]\[ \frac{8 \times 8}{5} = \frac{64}{5} \][/tex]
So, the product of [tex]\(1 \frac{3}{5}\)[/tex] and [tex]\(8\)[/tex] is [tex]\(\frac{64}{5}\)[/tex].
To express this as a mixed number, we divide [tex]\(64\)[/tex] by [tex]\(5\):[/tex]
[tex]\[ 64 \div 5 = 12 \text{ remainder } 4 \][/tex]
Thus, [tex]\(\frac{64}{5}\)[/tex] as a mixed number is [tex]\(12 \frac{4}{5}\)[/tex].
The final answer is[tex]\(12 \frac{4}{5}\) or \(\frac{64}{5}\).[/tex]
Solve for x in the following equation.
For this case we must find the value of "x" of the following equation:
[tex]x ^ 2-9 = 0[/tex]
So:
We add 9 to both sides of the equation:
[tex]x ^ 2-9 + 9 = 9\\x ^ 2 = 9[/tex]
We apply square root on both sides of the equation to eliminate the exponent on the left side:
[tex]x = \pm \sqrt {9}[/tex]
Thus, the solutions are:
[tex]x_ {1} = + 3\\x_ {2} = - 3[/tex]

Rewrite the following logarithm.
logxy
Step-by-step explanation:
[tex]\text{Use}\ \log_ab+\log_ac=\log_a(bc)\\\\\log(xy)=\log(x)+\log(y)\\\\\text{Where}\ x>0\ \text{and}\ y>0.[/tex]
Final answer:
To rewrite the logarithm log(xy), you apply the property that the logarithm of a product is equal to the sum of the logarithms of the individual factors, resulting in log x + log y.
Explanation:
The logarithm you are asked to rewrite is log(xy). According to the properties of logarithms, the logarithm of a product is equal to the sum of the logarithms of the individual factors. This means that log(xy) = log x + log y. This rule is useful for simplifying logarithmic expressions and is a direct consequence of how exponents work.
Another property to remember is that the logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number. This is expressed as log(xy) = y × log x.
Remember, both properties are fundamental in working with logarithms and can be applied regardless of the base of the logarithm, whether it's log to the base 10, ln for natural logarithms (to the base e), or any other base.

x=88 ?89 ? Or 90?
What is x= ?
Answer:
The measure of angle x is 90°
Step-by-step explanation:
Given the figure in which
∠1=88°, ∠6=89°
we have to find the value of x.
∠5=∠6=89° (∵ Vertically opposite angles)
∠1+∠4=∠6 ( ∵ By exterior angle property)
88°+∠4=89°
∠4=89°-88°=1°
As AC=CB (both are radii of same circle)
∴ ∠4=∠3=1°
Now, by exterior angle property
x=∠5+∠3=89°+1°=90°
Hence, the measure of angle x is 90°
Applying the angle of intersecting chords theorem, the value of x in the diagram showing the circle is: C. 90.
What is the Angle of Intersecting Chords Theorem?According to the angle of intersecting chords theorem, the measure of the angle formed at the point of intersection of two chords inside a circle equals half the sum of the intercepted arcs.
89 = 1/2(88 + x) [based on the angle of intersecting chords theorem]
2(89) = 88 + x
178 = 88 + x
178 - 88 = x
x = 90° (Option C).

6x + 3y = 27 5x+ 2y + 21
Which variable should he choose so that he can use substitution to solve the system?
Jon should solve for y in the first equation because the coefficients can be reduced by a common factor to eliminate the coefficient for y.
Jon should solve for x in the first equation because the coefficients can be reduced by a common factor to eliminate the coefficient for x.
Jon should solve for y in the second equation because the coefficients can be reduced by a common factor to eliminate the coefficient for y.
Jon should solve for x in the second equation because the coefficients can be reduced by a common factor to eliminate the coefficient for x.
The most efficient way to solve this problem is isolating the y in the first equation because:
6x + 3y = 27
3y = 27 - 6x
y = 9 - 2x
Since all the numbers have a common factor of 3, it can be easily simplified/reduce.

A lawnmower blade has a diameter of 36 inches and spins at a rate of 60 revolutions per minute.
Answer:
C. 2,160π
Step-by-step explanation:
took test
The linear velocity at the end of the blade is 13571.7 inches per minute by using the circumference of the circle that the blade makes to calculate the linear velocity at the end of the blade.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Here, The total distance in 1 minute is 60 times circumference of the circle made by the end of the blade of the lawnmower.
Since, The blade is 36 inches long, it can be taken as radius of that circle.
The circumference is thus calculated as;
⇒ linear velocity = 226.19 × 60

convert 150 degrees to radian
Answer:
A
Step-by-step explanation:
To convert degrees to radians
radian measure = degree measure × [tex]\frac{\pi }{180}[/tex]
Hence
radian measure = 150° × [tex]\frac{\pi }{180}[/tex]
Cancel both 150 and 180 by 30, then
radian measure = 5 × [tex]\frac{\pi }{6}[/tex] = [tex]\frac{5\pi }{6}[/tex]
Final answer:
To convert 150 degrees to radians, multiply 150 by π/180 to get 5/6 * π or approximately 2.61799 radians.
Explanation:
To convert 150 degrees to radians, we use the fact that one complete revolution is 360 degrees which is equal to 2π radians (approximately 6.28318 radians). From this, we can derive that 1 degree is equal to π/180 radians. We multiply the value in degrees by π/180 to get the equivalent in radians.
150 degrees * π/180 radians/degree = 150/180 * π radians = 5/6 * π radians.
Therefore, 150 degrees is equal to 5/6 times π or approximately 2.61799 radians.

C) 15
m
s
D) 20
m
s
Final answer:
The initial velocity at which she threw the cap is 20 m/s.
Explanation:
Since the cap comes back to her hand at the same height, the initial vertical velocity of the cap is 0 m/s. The acceleration due to gravity is -10 m/s². Using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time, we can solve for the initial velocity. In this case, v = 0 m/s, a = -10 m/s², and t = 2.0 s. Plugging in these values, we get:
0 = u + (-10)(2.0)
0 = u - 20
u = 20 m/s
So the initial velocity at which she threw the cap is 20 m/s.

Step-by-step explanation:
Given in the question a function, f(x) = x² + 4
initial value x0 = -3
4 times iteration means f(f(f(x)))First iteration
f(x0) = f(-3) = (-3)² + 4 = 13
x1 = 13
Second iteration
f(x1) = f(13) = (13)² + 4 = 173
x2 = 173
Third iteration
f(x2) = f(173) = (173)² + 4 = 29933
