MarkFL said:What type of plane figure is the given area?
Yazan975 said:It does not specify
MarkFL said:We can see that it is a trapezoid. A formula for the area \(A\) of a trapezoid is:
\(\displaystyle A=\frac{h}{2}(B+b)\)
where:
\(\displaystyle h\) is the height (we see is is 5 units)
\(\displaystyle B\) is the "big base" (this is unknown)
\(\displaystyle b\) is the "little base" (we see this is 2 units)
So, plugging everything we know into the area formula, we obtain:
\(\displaystyle \frac{35}{2}=\frac{5}{2}(B+2)\)
Solve this for \(B\)...what do you get?

Gradient in science refers to the rate of change of a physical quantity with respect to another quantity. It is a measure of how steep or gradual a change is over a given distance or time.
Gradient is calculated by taking the change in the value of a quantity divided by the change in the corresponding quantity. This can be represented as rise over run, or the change in y divided by the change in x. In mathematics, it is denoted as Δy/Δx.
Finding gradient is important in many scientific fields, such as physics, biology, and chemistry. It allows us to understand and analyze the rate of change of a physical quantity, which can help us make predictions, solve problems, and create models.
One technique for finding gradient is using the slope formula, which involves selecting two points on a graph and calculating the rise over run between them. Another technique is using the derivative, which is a mathematical tool for finding the rate of change of a function at a specific point.
One tip for finding gradient accurately is to use multiple data points instead of just two. This can provide a more accurate representation of the rate of change. It is also important to understand the units of the quantities involved and make sure they are consistent in order to avoid errors in calculation.
