What is the volume of this square pyramid? 384 cm³ 288 cm³ 192 cm³ 96 cm³.
Answer:
A. 384 cm3
Step-by-step explanation:
I took the quiz
v = 1/3 x area of base x height
volume = 1/3 x (12 x 12) x 8
= 384 cm3
this is the square pyramid you're talking about?
Solve for x angle Angles b c and A
Answer:
x = 30
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
The given is a right triangle so one of the angle is 90 degrees:
90 + 2x + x = 180 add like terms
90 + 3x = 180 subtract 90 from both sides
3x = 90 divide both sides by 3
x = 30
Which of the following sets of numbers could represent the three sides of a triangle?
Answer:
{ 14, 30, 33 }
Step-by-step explanation:
for the three sides to form a triangle.
The sum of any 2 sides > third side
{ 7, 22, 29 }
7 + 22 = 29 ← not greater than 3rd side, thus not form a triangle
{5, 7, 12 }
5 + 7 = 12 ← not greater than 3rd side, thus not a triangle
{ 8, 14, 24 }
8 + 14 = 22 < 24 ← sides do not form a triangle
{ 14, 20, 33 }
14 + 20 = 34 > 33
14 + 33 = 47 > 20
20 + 33 = 53 > 14
Thus the sides form a triangle
Line K has the equation 9x-4y=-5x4.
Line L is parallel to line K, but line L passes through the point (4,7).
The equation for L in slope-intercept form is_______
=======================================================
Explanation:
Line K is 9x-4y=-5*4 which is the same as 9x-4y=-20
Rule: Anything parallel to Ax+By = C is of the form Ax+By = D.
The equation 9x-4y=-20 has A = 9, B = -4 and C = -20.
That means Ax+By = D becomes 9x-4y = D.
------------------------------
Plug in the coordinates (x,y) = (4,7) and compute the value of D.
9x-4y = D
D = 9x-4y
D = 9(4)-4(7)
D = 36 - 28
D = 8
So 9x-4y = D becomes 9x-4y = 8
----------------------------
The last step is to solve for y to get the equation in y = mx+b form.
9x-4y = 8
-4y = 8-9x
-4y = -9x+8
y = (-9x+8)/(-4)
y = (-9x)/(-4) + 8/(-4)
y = (9/4)x - 2 is the slope-intercept form of line L
The equation is in y = mx+b form where,
m = 9/4 = slope
b = -2 = y intercept
How do I find the area of a circle's shaded region?
Answer: There are two ways you can do this; by radians or by degrees.
Step-by-step explanation: The formula used for calculating an area of a circle's shaded region in RADIANS is: A = (θ / 2) × r^2 and θ is equivalent to radians. The second formula used for calculating an area of a circle's shaded region in DEGREES is: (θ / 360) × πr2 where θ is equivalent to degrees.
A bacteria population decreases by a factor of 1/2 every 4 hours. Explain why we could also say that the population decays by a factor of (1/2 )^1/4 every hour.
Answer:
(1/2)^(t/4) = ((1/2)^(1/4))^t
Step-by-step explanation:
If time t is given in hours, then the number of 4-hour time periods is t/4. If the half-life is 4 hours, the population multiplier is ...
(1/2)^(t/4)
Using the rules of exponents, that can be rearranged to ...
(1/2)^((1/4)·t) = ((1/2)^(1/4))^t
That is, the multiplier every hour is ...
(1/2)^(1/4)
_____
The relevant rule of exponents is ...
(a^b)^c = a^(bc)

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15. N an 1 4 2 −12 3 36 the summation of 4 times negative 3 n, from n equals 4 to 15 the summation of 4 times negative 3 n, from n equals 1 to 15 the summation of 4 times negative 3 to the n minus 1 power, from n equals 1 to 15 the summation of 4 times negative 3 to the n minus 1 power, from n equals 4 to 15.
By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is [tex]\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]
What is sequence ?Sequence is collection of numbers with some pattern .
Given sequence
[tex]a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20[/tex]
We can see that
[tex]\frac{a_1}{a_2}=\frac{-10}{5}=-2\\[/tex]
and
[tex]\frac{a_2}{a_3}=\frac{20}{-10}=-2\\[/tex]
Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2
Now [tex]n^{th}[/tex] term of this Geometric progression can be written as
[tex]T_{n}= 5\times(-2)^{n-1}[/tex]
So summation of 15 terms can be written as
[tex]\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]
By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is [tex]\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]

5 A system of equations contains the Iines x+4y=2 and x-2y=c. When solving the system algebraically it is determined that x=6. What is the value of c in the second equation?
А. c=4
B. c=6
C. c=8
D. c=-4
Answer:
c = 8
Step-by-step explanation:
x = 6
from first equation : 6 + 4y = 2 → 4y = 2-6=-4 → y= -1
second equation : 6 -2(-1) = c → c = 6+2=8

Arrange the steps from start to finish to factor this expression using the grouping method x^2-5x-24 drag the tiles to the correct boxes not all tiles will be used step by step
Answer:
(x - 8)(x + 3)
Step-by-step explanation:
x² - 5x - 24
Consider the factors of - 24 which sum to give the coefficient of the x- term (- 5)
The factors are - 8 and + 3 , since
- 8 × + 3 = - 24 and - 8 + 3 = - 5
Use these factors to split the x- term
x² - 8x + 3x - 24 ( factor the first/second and third/fourth terms )
= x(x - 8) + 3(x - 8) ← factor out (x - 8) from each term
= (x - 8)(x + 3) ← in factored form
