Answer:
The explicit formula is;
Tn = 256(1/4)^(n-1)
The 9th term is;
256/65536
Step-by-step explanation:
Mathematically, we have the nth term of a geometric sequence as;
Tn = ar^(n-1)
a is the first term = 256
r is the common ratio = 64/256 = 16/64 = 4/16 = 1/4
So, for the 9th term, we have
T9 = 256(1/4)^(9-1) = 256/65536
The explicit formula is;
Tn = 256(1/4)^(n-1)

DUE SUNDAY I NEED ASAP
Answer:
x=43°
Step-by-step explanation:
The angles are adjacent and create a straight line so their sum is 180°.
(x+6)°+(3x+2)°=180°
x°+6°+3x°+2°=180°
4x°+8°=180°
4x°=172°
x=43°

Answer:
66 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the base area and h the perpendicular height )
A = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 cm² ( Area of triangular base ) and h = 11
V = 6 × 11 = 66 cm³
Which of the following shows a group of possible angles a triangle could have?
A. 10 degrees, 10 degrees, 10 degrees
B. 30 degrees, 30 degrees, 30 degrees,
C. 60 degrees, 60 degrees, 60 degrees
D. 80 degrees, 80 degrees, 80 degrees
Answer:
C. 60 degrees, 60 degrees, 60 degrees
Step-by-step explanation:
The measures of interior angles of a triangle sum to 180°.
Can anyone solve this question??? plss plsss its my request to all if any one can solve this question I will mark him/ her the brainliest
Answer:
a) ∠EAB = 180° - 90° - 30° = 60°
∠EBA = 180° - 90° - 60° = 30°
a) ∠EBA = 30°
b) ∠DCA = 180° - 90° - 30° = 60°
∠EBA ≅ ∠DAC, ∠EAB ≅ ∠DCA, ∠AEB ≅ ∠CDA
ΔEBA ≅ ΔDAC because of the AAA postulate
c) EB ≅ DA, EA ≅ DC, AB ≅ CA
d) AB = CA given
sin ∠EAB = EB/AB (sin 60°) EB = (0.8660)AB
cos ∠EAB = EA/AB (cos 60°) EA = (0.5)AB
cos ∠DAC = AD/CA (cos 30°) AD = (0.8660)CA
sin ∠DAC = CD/CA (sin 30°) CD = (0.5)CA
ED = EA + AD
ED = (0.5)AB + (0.8660)CA
since AB = CA, ED = 1.366CA
since EB = (0.8660)AB and AB = CA, then EB = 0.866CA
since CD = 0.5CA,
EB + CD = 0.866CA + 0.5CA = 1.366CA
EB + CD = 1.366CA
1.366CA = 1.366CA
Proof: ED = EB + CD

Answer:
1.47 years
Step-by-step explanation:
Given that,
The height of male elephant is given by the formula,
[tex]h=62.5\sqrt[3]{t} +75.8[/tex]
If h = 275 cm, we need to find the age of the elephant.
Put h = 275 cm in the above formula,
[tex]275=62.5\sqrt[3]{t} +75.8\\\\275-75.8=62.5\sqrt[3]{t}\\\\199.2=62.5\sqrt[3]{t}\\\\t=1.47\ years[/tex]
So, the required time be 1.47 years.

PLEASE HELPPPPPPPPPPPPPP
Answer:
None of these can be triangles.
Step-by-step explanation:
All triangles’ side lengths must follow this pattern - the two shortest sides must be GREATER than the longest when added together. 6 + 4 < 10, so this isn’t a triangle. 3 + 8 = 11, so this isn’t a triangle. 8.4 + 7.7 < 16.6, so this isn’t a triangle. Lastly, 4 + 3 < 16, so this isn’t a triangle. Hope this is accurate & helpful! Best of luck.
Paula and Simon are trying to find out if a different coin is biased. Paula throws this coin 10 times. She records the number of times the coin lands on heads. Simon throws the same coin 100 times. He records the number of times the coin lands on heads. Whose results will be more useful in deciding if the coin is biased? Give a reason for your answer.

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
Answer:
Step-by-step explanation:
The larger the number of throws the closer the results will be to the probability of a head. That is for a fair coin it should be close to 50%.
With only 10 throws you could get a result not close to 50% but the coin could still be fair.
So Simon's results ( 100 throws) would be more useful to decide if the coin is biased or not.

Answer:
[tex]\tan(A - \frac{\pi}{4}) = \frac{-\sqrt{15}- 1}{1 -\sqrt{15}}[/tex]
Step-by-step explanation:
Given
[tex]\tan A =-\sqrt{15[/tex]
Required
Find [tex]\tan(A - \frac{\pi}{4})[/tex]
In trigonometry:
[tex]\tan(A - B) = \frac{\tan A - \tan B}{1 + \tan A \tan B}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - \tan \frac{\pi}{4}}{1 + \tan A \tan \frac{\pi}{4}}[/tex]
[tex]tan \frac{\pi}{4} = 1[/tex]
So:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A * 1}[/tex]
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{-\sqrt{15}- 1}{1 -\sqrt{15}}[/tex]

What is the distance between the points (-4,5) and (8,9)?
Answer:
d ≈ 12.65Steps:
d² = (8-(-4))²+(9-5)²
d² = (8+4)² + 4²
d² = 12² + 4²
d² = 144 + 16
d² = 160
d = √160
d ≈ 12.65Ms Matthews has 200 sheets of construction paper she will give each of her 27 students an equal number of whole sheets to use for a project how many sheets will each students an equal number of whole sheets will each students get ? how sheets many will be left over?
Answer:
Each student will get 7 sheets with 11 sheets left over.
Step-by-step explanation:
divide 200 and 27 to get 7
7 sheets for each student
then multiply 27 and 7 to see how many sheets of paper she gave to her students.
that will give you 189
then 200-189=11 sheets left over

Answer:
(a+b)*(a+b)
c*c
(1/2*a*b)*4
Step-by-step explanation:
The area of a square is equal to side times side, so a+b=one of the sides of a square so you multiply this by another a+b to get the whole square
Same as the last part but c is equal to one side so we do c*c for the are
The area of a triangle is 1/2*base*height, so we do 1/2*a*b since a is equal to the base of the triangle and b is equal to the height. This is only equal to 1 triangle so we multiply this by 4 since there are 4 triangles in total
brass is an alloy of zinc and copper. if 30% of the content is zinc . find the weight of zinc and copper in 300 gram of brass.
Step-by-step explanation:
Here's your solution
=> percentage of zinc = 30%
=> total weight of alloy = 300 gram
=> amount of zinc = (30/100)*300 = 90 gram
=> amount of copper = 300 - 90 = 210 gram

What do you do to both sides to
r? What is r? 3/8 r = 6 HELP ME
Answer:
r = 16
Step-by-step explanation:
[tex]\frac{3}{8}r = 6 \\\\[/tex]
Multiply both sides by 8
[tex]8*\frac{3}{8}r = 6*8\\\\3r = 48\\[/tex]
Divide both side by 3
[tex]\frac{3}{3}r=\frac{48}{3}\\\\r = 16[/tex]
OR
Multiply both side by (8/3)
[tex]\frac{8}{3}*\frac{3}{8}r=6*\frac{8}{3}\\\\r = 2*8\\\\r = 16[/tex]
write an equation to represent the information in this problem. Jerel runs five days each week. on each of 4 days, he runs 2.3 km. if jerel runs a total of 14km, how many kilometers does he run on the fifth day?
Let x be the distance run on the fifth day
Total distance run on all the four days = 2.3 * 4 = 9.2 km
Required equation : x + 9.2 = 14
x = 14 - 9.2
x = 4.8 km
