Answer:
<em>a₅ = 506.25 option a</em>
Step-by-step explanation:
Given that,
first term a₁ = 1600
common ratio (r) =
We need to find the fifth term of the geometric progression
We know that the nth term formula
aₙ = a₁rⁿ-¹
where a₁ is first term and r is the common ratio
n is the number of terms
So, n = 5
a₅ = 1600
a₅ = 1600*
a₅ = 1600*81/256
a₅ =
<em>a₅ = 506.25 option a</em>
<em>That's the final answer</em>
Answer:
Graph B shows function f of x equals 4 multiplied by 3 to the power of negative x.
Step-by-step explanation:
is the value 4 times three raised to the negative x. Graph B is the best representation.
Hey there!!
(1) Both the angles sum up to be 180.
(2) Both the angles sum up to be 90
_________________
(1) 4x+5+8x-5=180
... 12x=180
... x= 180/12
... x = 15
________________
(2) 4z+3z+6=90
... 7z+6=90
... 7z=84
... z=84/7
... x=12

Answer:
Option B: 4
Step-by-step explanation:
From the image, the correct function is;
f(x) = x³ -5x² - 8x + 48
Now, the x-intercept occurs when y = 0.
Thus;
x³ - 5x² - 8x + 48 = 0
So we are looking for values of x that will make y = 0.
Let's try the options;
Let's try x = -4;
(-4)³ - 5(-4)² - 8(-4) + 48 = -64 - 80 + 32 + 48 = -64 ≠ 0
So, x = -4 is not an x - intercept
Let's try x = 4;
(4)³ - 5(4)² - 8(4) + 48 = 64 - 80 - 32 + 48 = 0
So,x = 4 is an x-intercept
Let's try x = - 2;
(-2)³ - 5(-2)² - 8(-2) + 48 = -8 - 20 + 16 + 48 = 36 ≠ 0.
So, x = -2 is not an x-intercept.
Let's try x = 2;
(2)³ - 5(2)² - 8(2) + 48 = 8 - 20 - 16 + 48 = 20 ≠ 0
So, x = 2 is not an x-intercept
