Answer:(-1.412,-2.124),(3.29,7.28)

Step-by-step explanation:

Given

The given equation is 2^x-2.5=2x+0.7

There are two functions i.e. y=2^x-2.5\ \text{and}\ y=2x+0.7

Their intersection gives the solution of the above function

From the graph, we can see that both the graph intersects at two different points i.e.  at

(-1.412,-2.124)\ \text{and}\ (3.29,7.28)

Ten times the sum of half a number and 6 is 8
nexus9112 [7]
Let the required number is 2x ,





According to the condition,



➡ 10 times the sum of half of 2x and 6 = 8

= > 10 \times ( \frac{2x}{2} + 6) = 8 \\ \\ \\ = > 10 \times (x + 6) = 8 \\ \\ \\ = > 10x + 60 = 8 \\ \\ \\ = > 10x = 8 - 60 \\ \\ \\ = > 10x = - 52 \\ \\ \\ = > x = - \frac{ 52}{10} \\ \\ \\ = > x = - 5.2



Therefore the value of x is -5.2


And, required number is -5.2

Find the value of x. if necessary, round to the nearest tenth a=47sq in
kipiarov [429]

the picture in the attached figure


we know that

area of the triangle is equal to

A=(b*h)/2


in this problem

A=47 in²

b=x

h=x

so

47=x*x/2 \\  x^{2} =94 \\ x= \sqrt{94}  \\ x=9.69 in \\ x=9.7in

therefore

the answer is

x=9.7 in

Find the greatest possible error for each measurement.<br> 10 1/8 oz
scoray [572]

<u>Answer:</u>

0.0005 oz

<u>Step-by-step explanation:</u>

Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.

It is normally half the place value of the last digit in a number.

Like here we have 10\frac{1}{8} oz which is equal to 10.125 oz. The last digit is 5 which is at the thousandth place (0.001) so the greatest possible error for this would be its half.

\frac{0.001}{2} = 0.0005 oz
