Find the missing length indicated​

Mathematics
1 answer:
poizon [28]3 years ago
4 0

Answer:

192

Step-by-step explanation:

Apply the geometric mean formula to solve for x, which is the altitude of the right triangle.

The formula is:

h = √(mn)

h = x = ?

m = 144

n = 400 - 144 = 256

Substitute

h = √(256*144)

h = √36,864

h = 192

Therefore, x = 192

Step-by-step explanation:

The load limit of the bridge is ...

  (5000 kg)(2.2 lb/kg) = 11,000 lb

The total of truck and trailer cannot exceed this value, so the trailer's weight cannot exceed ...

  11,000 lb -4,500 lb = 6,500 lb . . . max trailer weight

You start driving north for 24 miles, turn right, and drive east for another 10 miles. At the end of driving, what is your strai
yawa3891 [41]

Answer:

26 miles

Step-by-step explanation:

Given: 24 miles drive to north.

          10 miles drive to east.

Driving pattern form a right angle triangle, which has three leg including straight line distance from starting point (hypotenous).

Now, using Pythogorean theoram to find straight line distance from starting point.

h²= a²+b²

Where, h is hypotenous

            a is opposite leg

            b is adjacent leg.

⇒h²= 24^{2} + 10^{2}

⇒h^{2} = 576+100

⇒h^{2} = 676

Taking square root on both side, remember; √a²= ±a

⇒h=\sqrt{676}

∴ h= \pm 26

Ignoring -26 as distance cannot be negative.

Hence, 26 miles is the straight line distance from starting point.

alexandr1967 [171]

Answer:

  • multiplying a multi-digit number by itself several times (finding the power of a number)
  • finding a square root
  • statistical calculations

Step-by-step explanation:

We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)

If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.

___

All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.

What is the equation of the line? <br><br> Use y = mx+b
Olegator [25]

Answer:

y = - \frac{1}{2} x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 2) ← 2 points on the line

m = \frac{2-3}{4-2} = - \frac{1}{2}

Note the line crosses the y- axis at (0, 4) ⇒ c = 4

y = - \frac{1}{2} x + 4 ← equation of line
