Using the rules for significant figures, what do you get when you multiply 67.6 by 1.2?

Mumz [18]

If we use the rules we say that when we multiply two numbers we get the result in the numbers the least significant number has in the multiplication. So we may proceed like this:

67.6 x 1.2 = 81.12

As the decimal part does not continue indefinitely we can leave the answer as it is. if the answer was 81.123612356213 then we leave it like 81.1 as the rules say

The length of rectangular garden is 6 feet longer than the width. If the area of the garden is 16 square feet, find the length a

Lyrx [107]

Length = x + 6

Width = x

Area = 16 ft^2

The formula needed is A = L•W.

Here is the set up:

16 = (x + 6)(x)

16 = x^2 + 6x

x^2 + 6x - 16 = 0

Solve for x. After finding x, plug into the definition I gave above for length and width to find your answer.

Can any of you help me with this

RUDIKE [14]

If f(x)=2x^2+5√(x+2) then:

f(2)=2(2^2)+5√(2+2)

f(2)=2(4)+5√4

f(2)=8+5(2)

f(2)=8+10

f(2)=18

We assume the square root is positive unless otherwise indicated because this is a function and you can have only one y value for each x value to be a function.

One side of an isosceles triangle whose perimeter is 42 units measures 10 units. FInd the area of the triangle.

notka56 [123]

The area of the triangle is 75.99 units squared or approximately 76 units squared.

An Isosceles Triangle is a triangle with two congruent sides and two congruent angles. One side of the triangle measures 10 units, which is the base. The other two sides measures 16 units. The perimeter of the triangle is 10 + 16 + 16 = 42 units.

To get the area of a triangle, we use the formula
$A = \frac{1}{2} bh$

The height or altitude of the triangle can be calculated from Pythagorean theorem, which is equal to $\sqrt{231}$ units.

Substituting values into the formula for the area of a triangle, we get
$A = \frac{1}{2} (10)( \sqrt{231} ) \\ A =75.99 units squared \\$

The answer can be rounded of into 76 units squared.
