The square root of 7 lies between what two numbers

Mathematics

Dmitry [639]2 years ago

Remark

When ever you are asked a question like this one, the simplest answer is to find the rounded upper limit. Then go one number lower.Those are the two limits.

Solution

Use your calculator to get the exact answer. √7 = 2.64 roughly. Round up to get your first limit, even if it is closer to the lower limit. You always round up for the upper limit.

So far what you have is √7 <  3   Now subtract 1 from the 3.

2 < √7 < 3 Answer

The square root of 7 would like between 2 and 3. This is because 2 x 2 is 4's square root and 3 x 3 is nine's square root. Seven is between four and nine.

Find the amount of money accumulated if you invested $25,000 at 4.3% interest for 8 years compounded continuously .
MArishka [77]

The appropriate formula for the accumulated amount (A) for a given principal (P), interest rate (r), and time period (t) is ...

... A = P·e^(rt)

Filling in the given numbers and doing the arithmetic, we get

... A = $25,000·e^(.043·8) ≈ $35,264.46

In how many map squares did we spot more than 29 plant species
Katena32 [7]

Answer:

10 map squares.

Step-by-step explanation:

We have been given a histogram, which represents the plant species spotted in the animal reserve.

The x-axis represents the number of plant species and y axis represents the number of map squares.

We can see that 0 to 9 species are spotted in 1 map square.

10 to 19 and 20 to 29 plant species are spotted in 2 map squares.

To find the number of map squares that spot more than 29 plant species, we will count number of map squares that spot 30 to 49 plant species as 30 to 49 numbers are more than 29.

We can see from our histogram that 4 map squares spot 30 to 39 plant species and 6 map squares spot 40 to 49 plant species.

\text{Total number of map squares that spot more than 29 plant species}=4+6

\text{Total number of map squares that spot more than 29 plant species}=10

Therefore, 10 map squares spot more than 29 plant species.

Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB and cos ∠X = 2 and 5 tenths over 5 and 59 hundredths.
Maru [420]

Based on the above, the Triangle XYZ and ACB are known to be similar triangles since tanX = tanA = 5 over 2 and 5 tenths;

Hence:

  • AC = 2 x  XY
  • CB = 2  x YZ

<h3>What is the triangle about?</h3>

From the question given; Triangle XYZ is known to have been dilated by a scale factor of 2 to form a type of triangle known as triangle  ACB, So therefore, XYZ and ACB are known to be the same or similar triangles.

Since Angles Y and C are known to both measure 90 degrees, and angles A and X are said to be congruent. Therefore:

tanX = tanA = 5 over 2 and 5 tenths

AC = 2  x  XY

CB = 2  x  YZ

For part B:

cosX=Base/Hypotenuse

cos A=AC/AB

AC =  2.05

AB = 5.59

Therefore, Based on the above, the Triangle XYZ and ACB are known to be similar triangles since tanX = tanA = 5 over 2 and 5 tenths;

Hence:

  • AC = 2 x  XY
  • CB = 2  x YZ
