Answer:
Joshua read 186 books form 6 to 10 years of age.
Step-by-step explanation:
Joshua reads 6 books at the age of 6.
He doubled the number of books he read the previous years.
Now the sequence will be a geometric sequence as
6, 12, 24, ......
We have to calculate the number of books he read from 6 years to 10 years of his age.
Since sum of n terms of a geometric sequence is given by
[tex]S_{n}=\frac{a(r^{n}-1 )}{r-1}[/tex]
where a = first term
r = common ratio
n = number of terms
[tex]S_{5}=\frac{6(2^{5}-1 )}{2-1}[/tex]
= [tex]\frac{6(32-1)}{1}[/tex]
= 6×31
= 186 books
Therefore Joshua read 186 books form 6 to 10 years of age.

The hypotenuse of a 45°-45°-90° triangle measures 128 cm. What is the length of one leg of the triangle? 64 cm cm 128 cm cm
Answer:
Answer 64*sqrt(2)
Step-by-step explanation:
Givens
c = 128 cm
a = b = ??
formula
a^2 + b^2 = c^2 combine the two equal legs.
2a^2 = c^2 Substitute 128 for c
2a^2 = 128^2 Square
2a^2 = 16384 Divide by 2
a^2 = 16384/2
a^2 = 8192 Factor (8192)
8192 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 count the 2s
8192 = 2^13 Break 13 into 2 equal values with 1 left over
sqrt(8192) = sqrt(2^6 * 2^6 * 2^1)
sqrt(8192) = 2^6 * sqrt(2)
The length of one leg is 64*sqrt(2)
Answer:
Length of one leg of the given triangle will be 64√2 cm.
Step-by-step explanation:
Length of the hypotenuse of a 45°- 45°- 90° triangle has been given as 128 cm.
Since two angles other than 90° are of same measure so other two sides of the triangle will be same in measure.
Therefore, by Pythagoras theorem,
Hypotenuse² = Leg(1)² + Leg(2)²
Let the measure of both the legs is x cm
(128)² = 2x²
16384 = 2x²
x² = [tex]\frac{16384}{2}[/tex]
x² = 8192
x = √8192
= 64√2 cm
Therefore, length of one leg of the given triangle will be 64√2 cm.

By using the Pythagorean identity and the double angle identity for tangent, it is found that the value of tan 2θ when sin θ =24/25 and 0 ≤ θ ≤ π/2 is -527/336.
Explanation:In the field of Mathematics, particularly in trigonometric equations, the problem given is asking for the value of tan 2θ, given that sin θ=24/25 and 0 ≤ θ ≤ π/2.
Firstly, we can find cos θ by using the Pythagorean identity sin²θ + cos²θ = 1. This gives us cos θ = sqrt (1 - sin²θ) = sqrt (1 - (24/25)²) = 7/25.
Then, knowing that tan θ = sin θ/cos θ, we can plug in these values to get tan θ = (24/25) / (7/25) = 24/7. Finally, using the double angle identity for tan (tan 2θ = 2 tan θ / (1 - tan²θ)), we can find that tan 2θ = 2(24/7) / (1 - (24/7)²) = -527/336.
So, the exact value of tan 2θ when sin θ =24/25 and 0 ≤ θ ≤ π/2 is -527/336, which is answer option A.

Scenario:
A rectangular plot of ground is 5 meters longer than it is wide. Its area is 20,000 square meters.
Question:
What equation will help you find the dimensions?
Note: Let W represent the width.
Options:
w(w+5)=20,000
w^2=20,000+5
(w(w+5))/2=20,000
w+2(w+5)=20,000
To find the area you multiply the length by the width.
W = the width, and you are told the length is 5 meters longer, so the length would be (W +5)
Now multiply those together to equal 20,000 square meters:
w(w+5) = 20,000
What is the value of –2|6x – y| when x = –3 and y = 4?
Answer:
-44
Step-by-step explanation:
We have the expression
[tex]-2|6x - y|[/tex]
We need to find the value of the expression when x = -3 and y = 4
Then we must replace the variable with the number -3 and the variable y with the number 4
This is:
[tex]-2|6(-3) - (4)|[/tex]
[tex]-2|-18 - 4|[/tex]
[tex]-2|-22|[/tex]
Remember that the absolute value always results in a positive number.
So
[tex]-2|-22| = -2(22)=-44[/tex]
the answer is -44
Answer:
The correct answer is -44
Step-by-step explanation:
Points to remember
|x| = x
|-x| = x
To find the value of –2|6x – y|
We have –2|6x – y| When x = -3 and y = 4
Substitute the value of x and y
–2|6x – y| = –2|(6 * -3) – 4|
= -2|-18 - 4|
= -2|-22|
= -2 * 22
= -44
Therefore the value of –2|6x – y| when x = -3 and y = 4
–2|6x – y|

A takes 3 hours more than B to walk 30 km. But if A doubles his pace, he is ahead of B by 3/2 hours . Find their speed of walking.
Answer:
Initial speed:
A: [tex]\displaystyle \rm \frac{10}{3}\; km/ h[/tex].B: [tex]\rm 5\; km/ h[/tex].Step-by-step explanation:
Both equations are concerned about the time differences between A and B. To avoid unknowns in the denominators,
let [tex]x[/tex] be the initial time in hours for A to walk 30 km, andlet [tex]y[/tex] be the time in hours for B to walk 30 km.First equation:
"A takes 3 hours more than B to walk 30 km."
[tex]x = y + 3[/tex].
[tex]x - y = 3[/tex].
When A doubles his pace, he takes only 1/2 the initial time to cover the same distance. In other words, now it takes only [tex]x/2[/tex] hours for A to walk 30 km.
Second equation:
"[A] is ahead of B by 3/2 hours [on their 30-km walk.]"
[tex]\displaystyle \frac{x}{2} + \frac{3}{2} = y[/tex].
[tex]\displaystyle \frac{1}{2}x - y = -\frac{3}{2}[/tex].
Hence the two-by-two linear system:
[tex]\left\{\begin{aligned}&x - y = 3\\&\frac{1}{2}x - y = -\frac{3}{2}\end{aligned}\right.[/tex].
Solve this system for [tex]x[/tex] and [tex]y[/tex]:
Subtract the second equation from the first:
[tex]\displaystyle \frac{1}{2}x = \frac{9}{2}[/tex].
[tex]x = 9[/tex].
[tex]y = 6[/tex].
It initially takes 9 hours for A to walk 30 kilometers. The initial speed of A will thus be:
[tex]\displaystyle v = \frac{s}{t} = \rm \frac{30\; km}{9\; h} = \frac{10}{3}\; km/h[/tex].
It takes 6 hours for B to walk 30 kilometers. The speed of B will thus be:
[tex]\displaystyle v = \frac{s}{t} = \rm \frac{30\; km}{6\; h} = 5\; km/h[/tex].

Which polygon has an interior angle sum of 1080°?
Step-by-step explanation:
The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees. Because the octagon is regular, all of its sides and angles are congruent.Answer:
Octagon
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides, so
180° (n - 2) = 1080° ( divide both sides by 180° )
n - 2 = 6 ( add 2 to both sides )
n = 8 ← octagon

What is the quadratic function to these three points (-1,-11), (0,-3), and (3,-27)
Answer:
y = -4x² + 4x -3
Step-by-step explanation:
The standard form of quadratic equation is:
y = ax² + bx + c
We need to use the points given to find the value of a, b and c
We are given point (-1,-11) where x =-1 and y=-11 putting values in the above equation
y = ax² + bx + c
-11 = a(-1)² + b(-1) +c
-11 = a -b+c eq(1)
Now putting the point(0, -3) where x =0 and y =-3
y = ax² + bx + c
-3 = a(0)² + b(0) + c
-3 = 0 + 0 + c
=> c = -3
Now Putting the point (3, -27) where x =3 and y = -27
y = ax² + bx + c
-27 = a(3)² +b(3) + c
-27 = 9a + 3b + c eq(2)
Putting value of c= -3 in eq(2)
-27 = 9a + 3b -3
-27 +3 = 9a +3b
-24 = 9a + 3b
=> 3(3a+b) = -24
3a + b = -24/3
3a + b = -8 eq(3)
Putting value of c= -3 in eq(1)
-11 = a -b+c
-11 = a -b -3
-11 + 3 = a - b
-8 = a - b
=> a - b = -8 eq(4)
Now adding eq(3) and eq(4)
3a + b = -8
a - b = -8
__________
4a = -16
a = -16/4
a = -4
Putting value of a in equation 4
a - b = -8
-4 -b = -8
-b = -8+4
-b = -4
=> b = 4
The values of a , b and c are a= -4, b =4 and c= -3
Putting these values in standard quadratic equation
y = ax² + bx + c
y = -4x² + 4x -3
The measure of one angle of a right triangle is 44∘ more than the measure of the smallest angle. Find the measures of all three angles.
Answer:
Smallest angle = 23
Middle angle = 23 + 44 = 67
Right angle = 90
Step-by-step explanation:
Givens
Let the smallest angle = x
Let the middle angle = x + 44
Let the right angle = 90 which it always does.
All triangles = 180 degrees.
Equation
x + x + 44 + 90 = 180
Solution
2x + 44 + 90 = 180 Combine the left
2x + 134 = 180 Subtract 134 from both sides
2x +134-134 = 180 - 134 Combine
2x = 46 Divide by 2
2x/2 = 46/2 Do the division
x = 23
