Answer:
a5 = 2
Step-by-step explanation:
If a1 = 32,
a1 = 1/2 a0 = 32
a0 = 64
With that, we know that
a0 = 64,
a1 = 32
so, a2 is definitely 16. From that, we may know the formula,
an = a0 (1/2)^n
a5 = a0 (1/2)^5
a5 = 64 (1/32)
a5 = 2

Pythagora's Theorem
In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:
[tex]c^2=a^2+b^2[/tex]
Where
c = Hypotenuse or largest side
a,b = Legs or shorter sides
The situation described in the problem forms a right triangle shown in the image below.
Applying Pythagora's Theorem :
[tex]10^2=9^2+x^2[/tex]
Solving for x:
[tex]x^2=10^2-9^2[/tex]
[tex]x^2=100-81=19[/tex]
[tex]x=\sqrt{19}=4.4[/tex]

how do I solve the symptoms of linear equations by substitution
2x-y=23
x-9=-1
Answer:
x = 8, y = -7
in coordinate form: (8,-7)
Step-by-step explanation:
first, find x using the second equation:
x - 9 = -1
add 9 to both sides of the equation
x - 9 + 9 = - 1 + 9
x = -1 + 9
x = 8
next, substitute x for 8 in the first equation:
2x - y = 23
2 * 8 - y = 23
16 - y = 23
16 - y + y = 23 + y
16 = 23 + y
16 - 23 = y
y = -7

Domingo is replacing the baseboards in his home and calculates that he will need 637.5 feet of wood. When he travels to the hardware store, he discovers that baseboards are sold in 7.5-foot lengths. How many boards will Domingo need to purchase?
Answer:
Number of boards= 85
Step-by-step explanation:
Giving the following information:
Total wood required= 637.5 feet of wood
The baseboards are sold in 7.5-foot lengths.
To calculate the number of boards, we need to use the following formula:
Number of boards= total wood required / foot per board
Number of boards= 637.5 / 7.5
Number of boards= 85
Find the area of the shaded region. Round your answer to the nearest hundredth.
6 m
IT T
24 m
The area is about
square meters
The area of the shaded region in the circle to the nearest hundredth is 1695.60 meter squared.
Area of a circle
area = πr²
where
r = radius of the circleThe area of the shaded portion is the difference of the area of the large and small circle.
Therefore,
area of the large circle = πr²
area of the large circle = 3.14 × 24²
area of the large circle = 3.14 × 576
area of the large circle = 1808.64 m²
Therefore,
area of the small circle = 3.14 × 6²
area of the small circle = 3.14 × 36
area of the small circle = 113.04 m²
The area of the shaded region = 1808.64 - 113.04 = 1695.6 m²

Evaluate the expression when a=−15 and b=−5.
b2/a + 5
Answer:
-2.5Step-by-step explanation:
Evaluate the expression:
b²/(a + 5)When a= −15 and b=−5
Substitute values:
b²/(a + 5) =(-5)² / (-15 + 5) =25/(-10) =-2.5------------------------------------------------------------------
In case the expression is b²/a + 5, the value is:
b²/a + 5 =(-5)²/(-15) + 5 =25/(-15) + 5 =- 5/3 + 5 =10/3-------------------------------------------------------------------

4. At Sports Shoe Warehouse, the cost of 9 pairs of baseball shoes is $855 plus $92 for each additional pair.
From Winning Team Shoes, the cost of 9 pairs of baseball shoes is $810 plus an additional 7% for each
additional pair. For how many total pairs of baseball shoes does each vendor cost about the same?
Answer:
10.46
Step-by-step explanation:
Let the Number of additional pair = x
Ware house A :
855 + 92x - - - (1)
Warehouse B:
Initial cost per pair before 9
= 810 / 9 = $90
Additional 7% for pairs after 9
1.07 * 90 = 96.3
810 + 96.3x - - - (2)
810 + 96.3x = 855+ 92x
96.3x - 92x = 855 - 810
4.3x = 45
x = 45 / 4.3
x = 10.46
Additional pair be 10.46
Using the sum of the angle measures of a triangle, m angleC=?
Answer:
m∠C = 66°
Step-by-step explanation:
Given
m∠ A = 33°
m∠ B = 81°
To determine
m∠C = ?
We know that sum of angles of a triangle is 180°.
so using the equation
m∠ A + m∠ B + m∠C = 180°
substituting m∠ A = 33°, and m∠ B = 81° in the equatio
33° + 81°+m∠C= 180°
114° + m∠C = 180°
m∠C = 180° - 114°
m∠C = 66°
Therefore,
m∠C = 66°Is this a function? thanks for the answers:)

a sixth grade student can complete 20 multiplication facts in one minute if you works at the same rate how long should it take him to complete 35 multiplication facts? [type answer as decimal number.]
Answer:
It should take him 1.75 minutes to complete 20 multiplication facts, which is the same thing as 1 minute and 45 seconds, or 105 seconds.
Step-by-step explanation:
a. If it takes him one minute to complete 20 multiplication facts, that's 3 seconds per question, because 60/20 = 3.
b. Multiply 3 x 35 questions to get 105 seconds.
c. Divide 105 seconds by 60 seconds (60 in a minute) to get 1.75 minutes, which is the same thing as 105 seconds.

Find y.
Round to the nearest tenth:
31°
y
X
400 ft
y = [? ]ft
Answer:
y = 240.3 ft
Step-by-step explanation:
Use trigonometric ratio to find y:
Thus,
Reference angle = 90° - 31° = 59°
Opposite = 400 ft
Adjacent = y
Therefore:
Tan 59° = 400/y
Multiply both sides by y
y*tan 59 = 400
Divide both sides by tan 59
y = 400/tan 59
y = 240.3 ft (to the nearest tenth)

Answer: B
Step-by-step explanation:
The equation [tex]y+2=\frac{3}{4} x-8[/tex] is not yet in slope-intercept form([tex]y=mx+b[/tex]). Simply subtract 2 from both sides to turn the equation into slope intercept form as [tex]y=\frac{3}{4}x-10[/tex]. For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.
The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: [tex]y=-\frac{4}{3} x+b[/tex]. Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
[tex]1=-\frac{4}{3}*-12+b[/tex]
[tex]1=16+b[/tex]
[tex]-15=b[/tex]
Thus, the equation of the line is [tex]y=-\frac{4}{3} x-15[/tex], or B.
