Answer:

Step-by-step explanation:

As you can observe from the pattern, the numerator gets multiplied by 4 every increase in the sequence.

So , clearly, the 5th term will be = $\frac{64*4}{5} =\frac{256}{5}$

and the 6th term will be = $\frac{256*4}{5} =\frac{1024}{5}$

Therefore , D will be the answer.

line passes through the point (-3,-4) and its y-intercept is (o, -9). What is the equation of the line that is parallel to the f

12345 [234]

Answer:

$y=-\frac{5}{3}x-2$

Step-by-step explanation:

The first line has a slope of -5/3 found using the points in the slope formula.

$m=\frac{y_2-y_1}{x_2-x_1} =\frac{-9--4}{0--3}=\frac{-9+4}{0+3}=\frac{-5}{3}$

Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form $y-y_1=m(x-x_1)$ .

$y--7=-\frac{5}{3}(x-3)\\y+7 = -\frac{5}{3}(x-3)\\y=-\frac{5}{3}x + 5 -7\\y=-\frac{5}{3}x-2$

Solve for x in the following:<br> 8x^2 + 6x = -5

artcher [175]

Answer:

No solution or

(-3± $2i\sqrt{31}$ )/8

Step-by-step explanation:

To get the solution, move everything to the left side of the equation:

8x²+6x+5 = 0

If you try to factor the equation or graph it, you will see that it will never equal 0.

If you need an imaginary solution you can plug it into the quadratic equation:

-6± $\sqrt{36-160}$ over 16

Simplify and you get

-6± $i\sqrt{124}$ over 16

-6± $4i\sqrt{31}$ over 16

Simplify the fraction and you can get

(-3± $2i\sqrt{31}$ )/8

Viefleur [7K]

Answer:

113 feet

Step-by-step explanation:

Use the ratio 1:50 to calculate the height of the tower.

The scale model height is 2.25 feet, so multiply that by 50

2.25 x 50 = 112.5

Round to 113 feet

Solve for B and A please help ASAP

Mama L [17]

Answer:

∠A = ∠B = 80°

Step-by-step explanation:

The angles are corresponding angles where a transversal crosses parallel lines, so are congruent. That means ...

∠A = ∠B

8x -8° = 5x +25° . . . . . substitute the given expressions

3x = 33° . . . . . . . . . . . . add 8°-5x

x = 11° . . . . . . . . . . . . . . divide by 3

Then the angles are ...

8·11° -8° = 80°
