Answer:
B) is false
Explanation:
A triangle canot have 2 abtuse angles and one acute angle.
Answer:
B is false
Step-by-step explanation:
a is true because an equilateral triangle has three acute angles (60 degrees)
c is true because an iscoceles triangle can be drawn with one obtuse angle and two acute angles.
d is true because a right angled triangle can be drawn with one right angle and two acute angles.
b is false because neither an equilateral, iscoceles, right-angled, or scalene triangle can be drawn with two obtuse angles.

Sally’s wallet contains:
5 quarters
3 dimes
8 nickels
4 pennies
A coin is drawn from the purse and replaced 240 times. How many times can you predict that a nickle or a penny will be drawn?
Answer:
Nickles: 96 times
Penny: 48 times
Step-by-step explanation:
5+3+8+4 = 20 coins in total
20x = 240
x=12 (chance of a coin being picked)
8 nickles(12) = 96
4 pennies(12) = 48

The 7th term of a geometric progression is 48 the 8th term is -16 find the common ratio
Answer:
48 = 768* (r)^2
thus, r = 0.25
solving for a(7)
a(7) = 768 * (0.25)^(5)
a(7) = 0.75
Step-by-step explanation:
Answer:
r = - [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The common ratio r is calculated as
r = [tex]\frac{a_{8} }{a_{7} }[/tex] = [tex]\frac{-16}{48}[/tex] = - [tex]\frac{1}{3}[/tex]
which answer? (multiple choice).
Shauna says that 2x2 + x - 12 is the same as (x+4)(x-3). Is
she correct? Are the two expressions equal? Explain your
answer.
Answer:
Shauna is incorrect, because (x + 4)(x - 3) is NOT equivalent to 2x² + x - 12
Step-by-step explanation:
Check if she is correct by expanding (x + 4)(x - 3), with FOIL:
(x + 4)(x - 3)
x² - 3x + 4x - 12
x² + x - 12
So, Shauna is incorrect, because the two expressions are not equal.
(x + 4)(x - 3) is equivalent to x² + x - 12, NOT 2x² + x - 12.
Answer:
No she's wrongTwo equations are unequal.Explained belowStep-by-step explanation:
[tex] \sf \rightarrowtail \: (x + 4)(x - 3) \\ \sf \rightarrowtail \: x(x - 3) + 4(x - 3) \\ \sf \rightarrowtail \: {x}^{2} - 3x + 4x - 12 \\ \sf \rightarrowtail \: {x}^{2} + x - 12 \cancel{ = } {2x}^{2} + x - 12[/tex]
Which graph represents the solution set of this inequality? 12b-15>21
Answer:
b > 3, or D.
Step-by-step explanation:
Solve for b to get the equation of the inequality.
12b - 15 > 21
Add 15 to both sides.
12b > 36
Divide both sides by 12.
b > 3
Since it is greater than and not greater than and equal to, the initial dot will not be circled, which makes it either C or D.
Since it is greater than 3, it means it will be all values to the right of 3, which makes the answer D.

Answer:
Michelle$5Step-by-step explanation:
The dollar value of the 20% coupon will increase if the discount is from a larger amount. Applying the $25 coupon first reduces the amount that the 20% applies to, so reduces the dollar value of the 20% coupon.
Michelle used the 20% coupon first, so its value was 20%($100) = $20.
Natasha used the $25 coupon first, so the value of the 20% coupon was ...
20%($100 -25) = 20%(%75) = $15.
Michelle paid $20 -15 = $5 less.
Need help with this, finding the length of the third side
Answer:
its sqrt (50)
Step-by-step explanation:
The triangle has a right angle, therefore we can use the Pythagorean theorem to find the hypotenuse. According to the theorem the sum of the squares of both other sides is equal to the square of the hypotenuse.
We have 5^2+5^2=c^2
=> 25+25=c^2
=> 50=c^2
Therefore c or the missing side is equal to sqrt(50)
Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents
Given:
In a circle, two chords CE and DU intersect each other inside the circle at B.
Measure of arc CD = 185 degrees.
Measure of arc EU = 55 degrees.
To find:
The measure of angle CBD.
Solution:
Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.
Using Intersecting chords theorem, we get
[tex]m\angle CBD =\dfrac{1}{2}(arcCD+arcEU)[/tex]
[tex]m\angle CBD =\dfrac{1}{2}(185^\circ +55^\circ )[/tex]
[tex]m\angle CBD =\dfrac{1}{2}(240^\circ )[/tex]
[tex]m\angle CBD =120^\circ[/tex]
Therefore, the measure of angle CBD is 120 degrees.
Using a model of the prototype artillery, a ball is fired into the air with an initial upward velocity of 48 ft/s. Its height, h, in feet after t seconds is given by the function:
What height will the ball be when 2 seconds has passed?
In how many seconds will the ball reach its maximum height?
What is the ball’s maximum height?
After how many seconds will the ball hit the ground?
what is the volume of this triangular prism? the base is 12 ft the height is 6 ft and the bottom is 20 ft
Answer:
720 [tex]ft^3[/tex]
Step-by-step explanation:
Answer:
720 ft³
Step-by-step explanation:
Volume = Area Triangle times Length
Area triangle = 1/2(6x12) = 1/2(72) = 36 ft²
Volume = 36 ft² x 20 ft = 720 ft³
Volume = 720 ft³

Step-by-step explanation:
If f(1)=1 f(2)=2 and f(n)=2f(n-1)+3f(n-2) then find the value of f(6).
Answer:
f(6) = 182
Step-by-step explanation:
f(1) = 1
f(2) = 2
f(3) = 2f(2) + 3f(1) = 2(2) + 3(1) = 4 + 3 = 7
f(4) = 2f(3) + 3f(2) = 2(7) + 3(2) = 14 + 6 = 20
f(5) = 2f(4) + 3f(3) = 2(20) + 3(7) = 40 + 21 = 61
f(6) = 2f(5) + 3f(4) = 2(61) + 3(20) = 122 + 60 = 182

The limit is x---->4-
The negative show that x approaches from the left
Now
As x approaches 4 from the left ... Means This number should be less than 4 (<4) but really close to 4.
Let's pick a Number
Say 3.99
Substitute this... You have
3.99/3.99-4
3.99/-0.01
If we choose x to be 3.999
we will have
3.999/-0.001
Notice the pattern... As x approaches 4 from the left... This limit will approach NEGATIVE INFINITY
Why?
As you approach 4 from the left... 3.9,3.99,3.999... You notice that the denominator becomes negative and EXTREMELY SMALL... and when you divide by an extremely small Number..... You'll get a relatively HUGE VALUE(You can try this... Use a calc... Divide any number of choice by a very small number... say.. 0.0000001.... You'll get a huge result
In our case... The denominator is negative... So it Will Approach a very Huge Negative Number
Hence
Answer.. X WILL APPROACH NEGATIVE INFINITY.
Vertical asymptotes are the zeroes of the denominator of a function
The denom. is x-4
Equate to zero to get the asymptote
x-4=0
x=4
Hence... There will be a vertical asymptote at x=4.
