The third and fourth number in an exponential sequence 100 and 500. what are the first and second numbers in this sequence?
Answer:
4 and 20
Step-by-step explanation:
100 times 5 is 500. If we go backwards 500 ÷ 5 = 100.
100 ÷ 5 = 20. 20 ÷ 5 = 4.
An exponential sequence is a sequence that grows more every time. It would get really big really quickly.
The first and second numbers in this sequence is 4 and 20
Given that,
The third and fourth number in an exponential sequence 100 and 500.Based on the above information, the calculation is as follows:
[tex]= 500 \div 100[/tex]
= 5
And,
[tex]= 100 \div 5 = 20, \\\\20 \div 5 = 4[/tex]

Hi, I need help please!! Given that x=3 and x=-4 are the solution of the equation x2+ax+b=0, find the value of a and of b. Answer: a=1, b=-12. I don’t know how to get the answer. Please show your workings and explain. If you help me, I will give Brainliest Answer Award to you. The topic is simultaneous equations, algebra. This question is from a Grade 8 workbook.
Answer:
a = 1, b = - 12
Step-by-step explanation:
we know that x = 3 and x = - 4, so (x - 3) and (x + 4) must be the factors of the equation:
(x - 3)(x + 4)
x^2 + - 3x + 4x - 12
x^2 + x - 12
therefore a = 1 and b = - 12
Step-by-step explanation:
firstly substitute x=3 into [tex]x^{2} +ax+b=0[/tex]
[tex]3^{2} +3a+b=0[/tex]
9+3a+b = 0
b = -3a-9
secondly substitute x=-4 into [tex]x^{2} +ax+b=0[/tex]
[tex](-4)^{2} +(-4)a+b=0[/tex]
16-4a+b = 0
b = 4a-16
combine the equations above,
-3a-9 = b = 4a-16
so -3a-9 = 4a-16
7a = 7
a = 1
then substitute a = 1 into b = 4a-16 or b = -3a-9 (both are ok)
b = 4(1)-16 = -12 or b = -3(1)-9 = -12
Camelia misses 8 points on the first math test. She misses 5 points on the second math test. What integer represents the number of points Camelia misses on the first two tests?
Answer:

Find the measure of the radius of the inscribed circle of AABC.
Radius =
Answer:
Radius = 12
Step-by-step explanation:
For an inscribed circle of a triangle ABC,
GE = GF = GD = radius of the inscribed circle
Therefore, (-3y + 18) = (5y + 2)
-3y + 18 - 5y = 5y + 2 - 5y
-8y + 18 = 2
-8y + 18 - 18 = 2 - 18
-8y = -16
8y = 16
[tex]\frac{8y}{8}=\frac{16}{8}[/tex]
y = 2
Therefore, GE = -3y + 18
= -3(2) + 18
= -6 + 18
= 12
Radius of the inscribed circle = GE = 12 units
The measure of the radius of the inscribed circle is 12 units
From the given diagram, GE = GF
Given the following parameters:
GE = -3y + 18 and:
GF = 5y + 2
Equating both expressions
-3y + 18 = 5y + 2
-3y - 5y = 2 - 18
-8y = -16
y = 16/8
y = 2
The measure of the radius of the inscribed circle is GE
GE = -3y + 18
GE = -3(2) + 18
GE = -6 + 18
GE = 12 units
Hence the measure of the radius of the inscribed circle is 12 units

lin paid $94 for 6 meals. How much would 9 meals cost?
Answer:
140.4
Step-by-step explanation:
Answer:
$141.01 and if it is the nearest whole number it would be $141
Step-by-step explanation:
first you have to do 94 divided by 6. you do this to see how much 1 meal cost.
then you get: 15.67
now you take 15.67x3=47.01
cuz we need 3 more meals. we know this cuz we have 6 and want 9 so 6-9 is 3.
now we take 47.01+94=141.01
we just need to add 3 to the 6 we have to make 9 meals.
so your answer would be $141.01

At the end of a football season a coach is adding up everyone's scores nathan has scored 11 more than harry harry has scored 10 more then jack. If the total of their scores is 91, how much did harry score
Answer:
Harry has a score of 30
Step-by-step explanation:
Let us represent their scores as:
Nathan = x
Harry = y
Jack = z
At the end of a football season a coach is adding up everyone's scores
Nathan has scored 11 more than harry
x = y + 11
Harry has scored 10 more then jack.
y = z + 10
z = y - 10
If the total of their scores is 91
x + y+ z = 91
y + 11 + y + y - 10 = 91
3y + 1 = 91
3y = 91 - 1
3y = 90
y = 90/3
y = 30
Since Harry's score is represented as y, Harry has a score of 30
A length of pipe is 6cm to the nearest meter. Complete the error interval for the length of pipe.
Answer:
My answer
Step-by-step explanation:
First you convert it and it is 0.06 m. This is because
Conversion factor: 1 m = 100 cm
1) m = cm / 100
2) m = 6 / 100
3) m = 0.06
Then you do the error interval. Error interval – the range of values (between the upper and lower bounds) in which the precise value could be. Thn you caculate it by when you do this x2 then do <. For example 5>3. The do that there now you should have the answer. Dont frget put L in frount of 0.06 x2. Thank you. Hoped this helped! :)
The sum of the measures of angles for a triangle is 180°. Find the value of x and then the measures of the 3 angles
Answer:
The value of x is 50
The measures of the 3 angles are 50°, 100°, 30°
Step-by-step explanation:
Let us solve the question
∵ The sum of the measures of the angles of a triangle is 180°
∵ The measures of the 3 angles of the given Δ are x°, 2x°, (x - 20)°
→ Add them and equate the sum by 180
∴ x° + 2x° + (x - 20)° = 180°
→ Add the like terms
∵ (x + 2x + x) + (-20) = 180
∴ 4x - 20 = 180
→ Add 20 to both sides
∵ 4x - 20 + 20 = 180 + 20
∴ 4x = 200
→ Divide both sides by 4 to find x
∴ x = 50
∴ The value of x is 50
To find the measures of the 3 angles substitute x by 50 in their expressions
∵ The measure of one angle is x
∴ The measure of the 1st angle is 50°
∵ The measure of the 2nd angle is 2x
∴ The measure of the 2nd angle = 2(50)
∴ The measure of the 2nd angle is 100°
∵ The measure of the 3rd angle is (x - 20)
∴ The measure of the 3rd angle = (50 - 20)
∴ The measure of the 3rd angle is 30°
∴ The measures of the 3 angles are 50°, 100°, 30°

for questions 3 & 4. Determine whether the triangles are similar. If similar, state how (SA, SSS, or SAS), and write a similarity statement
9514 1404 393
Answer:
3. ΔBEA ~ ΔBCD by AA
4. ΔPXY ~ ΔPQR by SSS
Step-by-step explanation:
3. The missing angle in ΔBEA is angle E, which has measure ...
∠E = 180° -42° -53° = 85°
So, angle E matches angle C, and the vertical angles match. The two triangles are similar by AA. The corresponding angles are B:B, and E:C, so the similarity statement needs to reflect that: ΔBEA ~ ΔBCD.
__
4. Shortest-to-longest, the side ratios of the two triangles are ...
12 : 15 : 18 = 4 : 5 : 6
and
16 : 20 : 24 = 4 : 5 : 6
Side ratios are proportional, so the triangles are similar by SSS. The similarity statement can reflect the same ordering: ΔPXY ~ ΔPQR.
1) Anna and Jason have summer jobs stuffing envelopes for two different companies. Anna earns $20 for every 400 envelopes she finishes. Jason earns $10 for every 250 envelopes he finishes.
A) Create tables, draw graphs, and write equations that show the earnings, y, as functions of the number of envelopes stuffed, x, for both Anna and Jason.
Answer:
The answer is below
Step-by-step explanation:
A) i)
For Anna initially, she has $0 from making 0 envelopes. After making 400 envelopes she has $20. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{20-0}{400-0}(x-0)\\\\y=\frac{1}{20} x[/tex]
The table is:
x: 200 400 600 800 1000
y: 10 20 30 40 50
ii)
For Jason initially, he has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{10-0}{250-0}(x-0)\\\\y=\frac{1}{25} x[/tex]
The table is:
x: 200 400 600 800 1000
y: 8 16 24 32 40
The graph is plotted using geogebra online graphing
