Answer:
what equation below? :/
Step-by-step explanation:
Answer:
![y = 5](https://tex.z-dn.net/?f=%20y%20%3D%205)
Step-by-step explanation:
Given:
An isosceles triangle ABC with AB = AC.
∠A = ![(4y+10)\°](https://tex.z-dn.net/?f=%284y%2B10%29%5C%C2%B0)
∠B = ![75\°](https://tex.z-dn.net/?f=%2075%5C%C2%B0)
∠C = ![(3x)\°](https://tex.z-dn.net/?f=%283x%29%5C%C2%B0)
We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.
Therefore, ∠B = ∠C
⇒ ![75 = 3x](https://tex.z-dn.net/?f=75%20%3D%203x)
⇒ ![x=\frac{75}{3}=25](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B75%7D%7B3%7D%3D25)
∴ ∠C =
°
Now, the sum of all the interior angles of a triangle is always 180°.
![\angle A + \angle B + \angle C=180\\(4y+10)+75+75=180\\4y+10+150=180\\4y+160=180\\4y=180-160\\4y=20\\y=\frac{20}{4}=5](https://tex.z-dn.net/?f=%5Cangle%20A%20%2B%20%5Cangle%20B%20%2B%20%5Cangle%20C%3D180%5C%5C%284y%2B10%29%2B75%2B75%3D180%5C%5C4y%2B10%2B150%3D180%5C%5C4y%2B160%3D180%5C%5C4y%3D180-160%5C%5C4y%3D20%5C%5Cy%3D%5Cfrac%7B20%7D%7B4%7D%3D5)
Therefore, the value of 'y' is 5.
Answer:
- <u>The multiplicative rate of change of the function is 0.5</u>
Explanation:
The <em>multiplicative rate of change</em> is the ratio between consecutive entries.
Naming r the multiplicative rate of change, if it is constant you get:
- r = second entry / first entry = third entry / second entry = fourth entry / third entry.
Here:
- second entry / first entry = 0.125 / 0.25 = 0.5
- third entry / second entry = 0.0625 / 0.125 = 0.5
- fourth entry / third entry = 0.03125 / 0.0625 = 0.5
Thus, the multiplicative rate of change is 0.5. It means that you can obtain each entry as the product of the previous entry times 0.5:
- 0.25 × 0.5 = 0.125
- 0.125 × 0.5 = 0.0625
- 0.0625 × 0.5 = 0.03125
In general, exponential functions have constant multiplicative rate of changes.
