Answers

Answer 1

Answer: log4 + logx = log4x 4x = 28 x = 7
Easy cheesy! :) hope I helped. all you had to do is to divide 28/4 which is 7x

If the sixth term of a sequence is 128 and the common ratio is 2, then what is the first term?1
2
4

Answers

Answer: The first term of the sequence is 4.

Step-by-step explanation:

Let a be the first term of the sequence,

Here, the common ratio of the sequence is 2,

Thus, the sequence is,

a, 2a, 4a, 8a, 16a, 32a, .............., so on,...

Since, the sixth term of the sequence = 32a

According to the question,

32 a = 128

⇒ a = 4

Thus, the first term of the sequence is 4.

Hello,

Answer C: 4

$u_(6)=128$
$u_(5)=64$
$u_(4)=32$
$u_(3)=16$
$u_(2)=8$
$u_(1)=4$

For wich values of x does 2x^2+10x

Answers

2x^2 + 10x doesn't do anything, unless it's equal to something.

All you've got so far is a number. We can't even tell what it is
until we know what number 'x' is.

Is there another little part of the question that you didn't copy ?

Factor out at 2 so 2(x+5)(x+0)
Set them equal to 0 so
2=0 that's not a solution
X+5=0 so x=-5 that works
And the last one x=-0 well negative 0 doesn't exist so the only value that works is -5

I need help good explanation and answer for more points

Let's start with sectioning off the little squares on the left that are jutting out of the top and bottom. Both of the squares are C*E, so multiply C*E twice to get the area of those little squares. That comes out to 12 feet.

Next is the main quadrilateral, the big one. You have to cut it off at the point the triangle starts to slope, so the end fo B.

But you also have to get the left part, so you have to add the length of C to the length of B to get the length of the quadrilateral. A encompasses the entire height, but not the part we want, because we already isolated those little squares. To get the height, just subtract the two E parts. The height is 6. The length is 8 feet. Multiply and get 48.

Add that to the previous 12 feet calculated to get 60.

Next, the triangle. The height is A, but only with one E. So subract the other E to get a height of 9. The length is D, but you have to subract B because that is part of the earlier quadrilateral. That makes it 9.

The formula for a triangle is height * length / 2. So, plug in the numbers-- 9 * 9 / 2

81/2

40.5.

Add to the previous 60 we got and that makes 100.5 square feet.

Hope this helped!

Tiana can clear a football field of debris in 3 hours. Jacob can clear the same field in 2 hours. If they decide to clear the field together, how long will it take them?50 minutes

The answer is D. 5 hours, due to the fact that there football field together, so adding there times they had done the football field individually, Tiana,3 hours, and Jacob 2 hours 2h+3h=5hours. hope i helped.

Mona solved an equation incorrectly, as shown below:Step 1: 5x = 30
Step 2: x = 30 − 5
Step 3: x = 25

Which statement best explains why Step 2 is incorrect in Mona's solution?

She did not add 5 to 30.

She did not divide 30 by 5.

She did not multiply 30 by 5.

She did not multiply 30 five times.
