Answer:
Step-by-step explanation:
<h2>Given that :</h2>
- The radius of a circle is 2.9 in.
<h2>to find :</h2>
- Find the circumference to the nearest tenth.
<h2>formulas used :</h2>
- circumference = 2 × π × r
where,
<h2>explanation :</h2>
⟼ c = 2πr
⟼ c = 2 × 22/7 × 2•9 inches
⟼ c = 2 × 3•14 × 2•9 inches
⟼ c = 6•28 × 2•9 inches
⟼ c = 18•21 inches.
<h2>Round to the nearest tenth :</h2>
⟼ c = 18•21 inches
⟼ c = 20 inches
∴ circle circumference is 20 inches .
Answer:
Step-by-step explanation:
Let us consider the equation
For a quadratic equation in a standard form, 
, the axis of symmetry is the vertical line 
.
Here in this case we have, 
Putting the values we get,
We can see that the axis of symmetry is x=3 and the graph is giving minimum at x=3.
Therefore, the required equation is . Refer the image attached.
Answer:
I think right answer is integers
Answer:
(-7, -10)
Step-by-step explanation:
Solve for x and y in double variable equation
y = 2x + 4
y = x - 3
y = x - 3, plug in to first equation
x - 3 = 2x + 4
x = -7
y = -7 - 3
y = -10
(-7, -10)
