What is the rule for the following geometric sequence? 64,128,256,512...

professor190 [17]

Answer:

Step-by-step explanation:

The explicit rule for a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 64 and r = $\frac{a_{2} }{a_{1} }$ = $\frac{128}{64}$ = 2 , then

$a_{n}$ = 64 $(2)^{n-1}$ → B

Help meh pls

melamori03 [73]

The answer should be A because point slope form is y-y1=m(x-x1)....M is the starting point and its -56 and y1(-4) is the y value of the coordinate point and x1(8) is the x value of the coordinate point. it changes to y+4 because two negative signs make a positive(y--4)

Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two dista

svlad2 [7]

Answer:

A is the midpoint

Step-by-step explanation:

Given

A(5.2) B(6,-3) and C(4.7)

Required

Which is the midpoint

Midpoint is calculated using:

$(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)$

Testing A as the midpoint, we have:

$(5,2) = \frac{1}{2}(6+4,-3+7)$

$(5,2) = \frac{1}{2}(10,4)$

$(5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)$

$(5,2) = (5,2)$

<em>The above equation is true. Hence, A is the midpoint of B and C</em>

Answer: g(x) is -x² -3

Step-by-step explanation:

First, you know that the parabola is facing downwards, so the x must be negative.

Next, it is 3 units down from the parent graph, which adds that -3.

All of these add up to get your final equation:

g(x) is -x² -3

What other information do you need in order to prove the triangles congruent using the SAS congruence postulate

iren [92.7K]

AC is perpendicular to BD.

<h3>Further explanation</h3>

We observe that both the ABC triangle and the ADC triangle have the same AC side length. Therefore we know that $\boxed{ \ \overline{AC} \cong \overline{AC} \ }$ is reflexive.
The length of the base of the triangle is the same, i.e., $\boxed{ \ \overline{BC} = \overline{CD} \ }$ .
In order to prove the triangles congruent using the SAS congruence postulate, we need the other information, namely $\boxed{ \ AC \bot BD \ }$ . Thus we get ∠ACB = ∠ACD = 90°.

Conclusions for the SAS Congruent Postulate from this problem:

$\boxed{ \ \overline{BC} = \overline{CD} \ }$
∠ACB = ∠ACD
$\boxed{ \ \overline{AC} = \overline{AC} \ }$

The following is not other or additional information along with the reasons.

∠CBA = ∠CDA no, because that is AAS with ∠ACB = ∠ACD and $\boxed{ \ \overline{AC} \cong \overline{AC} \ }$
∠BAC = ∠DAC no, because that is ASA with $\boxed{ \ \overline{AC} \cong \overline{AC} \ }$ and ∠ACB = ∠ACD.
$\boxed{ \ \overline{BC} = \overline{CD} \ }$ no, because already marked.

Notes

The SAS (Side-Angle-Side) postulate for the congruent triangles: two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle; the included angle properly represents the angle formed by two sides.
The ASA (Angle-Side-Angle) postulate for the congruent triangles: two angles and the included side of one triangle are congruent to two angles and the included side of another triangle; the included side properly represents the side between the vertices of the two angles.
The SSS (Side-Side-Side) postulate for the congruent triangles: all three sides in one triangle are congruent to the corresponding sides within the other.
The AAS (Angle-Angle-Side) postulate for the congruent triangles: two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.
