Answer:
d. 140
Step-by-step explanation:
QTR is a 180 degree angle, so we can assume PTR is 140 degrees because (x+28) is (12+28)= 40
Answer:
<em>y= -3</em>
<em>x= 0</em>
Step-by-step explanation:
I will give the explanation in picture, hope you can understand it.
2/6, 3/9, 4/12, 5/15, 6/18 ect.
Hope this helped!
Answer:
Answer is 135 plant
Step-by-step explanation:
We have given that,
In 5 min Renee can plant 15 plant.
That means in one minute Renee can plant 
plant.
i.e. Rate of planting = 3 plant per minute
So, In 45 minutes , she can plant 45×3 plant
i.e Plant she can plant in 45 minute = 135 plant
Answer:
It can be determined if a quadratic function given in standard form has a minimum or maximum value from the sign of the coefficient "a" of the function. A positive value of "a" indicates the presence of a minimum point while a negative value of "a" indicates the presence of a maximum point
Step-by-step explanation:
The function that describes a parabola is a quadratic function
The standard form of a quadratic function is given as follows;
f(x) = a·(x - h)² + k, where "a" ≠ 0
When the value of part of the function a·x² after expansion is responsible for the curved shape of the function and the sign of the constant "a", determines weather the the curve opens up or is "u-shaped" or opens down or is "n-shaped"
When "a" is negative, the parabola downwards, thereby having a n-shape and therefore it has a maximum point (maximum value of the y-coordinate) at the top of the curve
When "a" is positive, the parabola opens upwards having a "u-shape" and therefore, has a minimum point (minimum value of the y-coordinate) at the top of the curve.
