Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.
I hope this helps!
Answer:
x=11
Step-by-step explanation:
3x+3(5x-6)= 180
Distribute 3 to 5x and -6
3x+15x-18=180
Combine like terms
18x-18=180
Add 18 to both side
18x=198
Divide 18 on both side
x=11
Answer: 1.5 less than 15 is divided by a number d.
Step-by-step explanation:
The width is 2.7 metres, and 3.2 × 2.7 = 8.64 is the length.
Therefore, area of the rectangle is 2.7 × 8.64 which will come to 23.328 metres squared.
If you need to round to two decimal places, it's 23.33.
B)70 because sina=cos(90-a)
