1.in triangle ADB and ADC
a. AB=AC a.given
b.BD=CD b. radii of same circle
c. AD=AD c. common side
2. ∵triangle ADB is congurent to 2. by S.S.S axiom
ADC
Answer:
AD cuts BC at I => I is the midpoint of BC => BI = CI
ΔAIB and ΔAIC have:
AB = AC
BI = CI
m∠ABC = m∠ACB ( because ΔABC is a isosceles triangle)
=> ΔAIB ≅ ΔAIC (sas)
=> m∠BAD = m∠CAD
ΔADB and ΔADC have:
m∠BAD = m∠CAD
AB = AC
AD is the common edge
=> ΔADB ≅ ΔADC (sas)

Mitchell swims several times per week in a lake near his home. Last summer, the average water temperature was 20 degrees Celsius. This summer, the average water temperature was 21 degrees Celsius. What was the percent of increase in the temperature?
Answer:
5% increase
Step-by-step explanation:
last Summer was 20° , this Summer is 21° so is 1° more so the question is what is the increase 1° of 20
20° is to 100% as
1° is to ?%
cross multiply
?% *20 =1*100
divide by 20 both sides
?%= 100/20 = 5

If you have a positive x coordinate and a negative y coordinate (2,-3) and you have to reflect it across the x axis is the -3 going to stay the same or become positive? If you could answer the question fast I would be grateful.
Answer:
The -3 would become positive.
Step-by-step explanation:
When reflecting over the x or y-axis, the x-coordinate and y-coordinate will always flip to it's opposite.

Approximately how long will it take for $700 to double if it is invested at 4% annual
interest, compounded continuously?
Round your final answer to the nearest whole year and do not label units.
Answer: 17 years
Step-by-step explanation:
Exponential equation for compund amount( compunded continuously):
[tex]A=Pe^{rt}[/tex] , where P= Principal value , r= rate of interest , t= time.
Given: A= 2P
r =4%= 0.04
To find : t
Substitute all values in the formula , we get
[tex]2P=Pe^{0.04t}\\\\\Rightarrow\ 2=e^{0.04t}[/tex]
Taking natural log on both sides
[tex]\ln2=\ln e^{0.04t }\\\\\Rightarrow\ 0.693147=0.04t\\\\\Rightarrow\ t=\dfrac{ 0.693147}{0.04}\\\\\Rightarrow\ t=17.3286\approx17[/tex]
hence, it will take 17 years (approx).

the graph is of a function in the form p(t)=a times b^t. what is the function?
9514 1404 393
Answer:
p(t) = 5×2^t
Step-by-step explanation:
You are given a couple of points, so can find the values of 'a' and 'b' in the function.
p(0) = 5
p(0) = a×b^0 = a
a = 5
__
p(1) = 10
p(1) = 5×b^1
10 = 5b
2 = b . . . . divide by 5
__
Now you know the function is ...
p(t) = 5×2^t
The figures are similar. Find the missing length.Round to the nearest thousandth
Answer:
The missing x = 0.675 m
Step-by-step explanation:
In similar triangles, the corresponding sides are proportion (means their ratios are equal)
In the given figure
∵ The two triangles are similar
∴ Their corresponding sides are proportion
∵ The sides of lengths 1.8 m and x are corresponding sides
∵ The sides of lengths 8.0 m and 3.0 are corresponding sides
∴ [tex]\frac{1.8}{x}[/tex] = [tex]\frac{8.0}{3.0}[/tex]
→ By using cross multiplication
∴ x × 8.0 = 1.8 × 3.0
∴ 8x = 5.4
→ Divide both sides by 8
∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{5.4}{8}[/tex]
∴ x = 0.675
→ No rounding because there is no digit after the thousandth digit
∴ x = 0.675 m
Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys.
Answer:
B ≤ 3.7
Step-by-step explanation:
Total money with Alonso = $21
Cost of Eggs = $2.50
Cost of Avocados in bags of 3 = $5
Let
B = number of bags of avocados that Alonso buys.
The inequality is:
Cost of Eggs + Cost of Avocados in bags of 3 ≤ Total money with Alonso
2.50 + 5B ≤ 21
5B ≤ 21 - 2.50
5B ≤ 18.5
B ≤ 18.5/5
B ≤ 3.7
The number of bags of avocados Alonso bought can be represented by B ≤ 3.7
Answer:
1) The inequality that describes this scenario is 2.50+5B≤21
2) Alonso can afford at most 9 avocados.

Jane invested her savings in two investment funds. The amount she invested in Fund A was $6000 less than the amount she invested in Fund B. Fund A returned a 8% profit and Fund B returned a 2% profit. How much did she invest in Fund B, if the total profit from the two funds together was $1220 ?
Answer:
Jane invested $37,000 in Fund B.
Step-by-step explanation:
Let;
IA = Amount invested in Fund A = $6,000
IB = Amount invested in Fund B = ?
PA = Amount of profit from Fund A = IA * 8% = $6,000 * 8% = $480
PB = Amount of profit from Fund B = IB * 2%
Therefore, we have:
Total profit = PA + PB = $1220 ........................ (1)
Substitute the relevant values into equation (1) and solve for IB, we have:
$480 + (IB * 2%) = $1220
IB * 2% = $1220 - $480
IB * 2% = 740
IB = 740 / 2%
IB = $37,000
Therefor, Jane invested $37,000 in Fund B.

What is the equation of the circle with center (16, - 12) and a radius of 5
Answer:
x^2+y^2-32x+24y+375=0
Step-by-step explanation:
Equation of circle with given centre (h,k) and radius=r is
(x-h)^2+(y-k)^2=r^2
Given centre are=(16, - 12) and radius= 5
So equation of circle=
(x-16)^2+(y- -12)^2=5^2
x^2-32x+256+y^2+24y+144=25
x^2+y^2-32x+24y+375=0

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.
y = 3x −24y = 3x −24
y = 3x + 24
y = -3x + 24
y = -3x - 24
Step-by-step explanation:
let eqn be y = mx + b.
3y = x - 15
y = 1/3x - 5
perpendicular means product of grad = -1
hence m = -3.
sun (8, 0):
8 = -3(0) + b
b = 8
therefore, equation if the line is y = -3x + 8

Adjust the window so you can find all of the points of intersection for the system of equations. What are the roots of the original polynomial equation? Check all that apply. –6 0 6 –4 3 8
Answer:
Your answer would be 6, -4, and 3
Step-by-step explanation:
The roots of the original polynomial equation are 6, -4 and 3
How to determine the root of the polynomial?The polynomial equation is given as:
P(x) = (x - 6)(x + 4)(x - 3)
Set the polynomial to 0
(x - 6)(x + 4)(x - 3) = 0
Split the equation
(x - 6) = 0, (x + 4) = 0 and (x - 3) = 0
Solve for x in each split
x = 6, x = -4 and x = 3
Hence, the roots of the original polynomial equation are 6, -4 and 3
