For January the range would have to be 1.2 since to find the range you have to subtract the largest number which is 2.5 by the smallest number which is 1.3. June's range would be

What is the sum of the integers between the square root of 12 and 40?

satela [25.4K]

1.

the closest perfect squares of 12 are 9 and 16,

that is 9<12<16

so
$\sqrt{9}\ \textless \ \sqrt{12}\ \textless \ \sqrt{16}$

$3\ \textless \ \sqrt{12}\ \textless 4$

this means, $\sqrt{12}$ is 3 point something...

2.

similarly

36<40<49

so

$\sqrt{36}\ \textless \ \sqrt{40}\ \textless \ \sqrt{49}$

$6\ \textless \ \sqrt{40}\ \textless \ 7$

which means $\sqrt{40}$ is 6 point something...

3.

<span>the sum of the integers between the square root of 12 and 40 is the sum of 4, 5 and 6, since 4 is the smallest integer after root 12, and 6 the greatest integer to before root of 40.

Write the number 33×10^-3 in scientific notation

cluponka [151]

Answer:

Step-by-step explanation:

33×10^-3 is equivalent to 33/1000, or 0.033.

This, in turn, is equivalent to 3.3×10^(-2) (which is in scientific notation)

What is the value of x?<br><br> sin(x+22)°=cos(2x−7)°

Snezhnost [94]

Remember that $\sin(\theta) = \cos(90^\circ - \theta)$

Thus, we can solve for x.
x + 22 = 90 - (2x - 7)
x + 22 = 97 - 2x
3x + 22 = 97
3x = 75
x = 25

The graph below represents the function f.

OLEGan [10]

Answer: А.

The function f intersects the x-axis at two points, and the function g never intersects the x-axis.

Step-by-step explanation:

In the graph we can see f(x), first let's do some analysis of the graph.

First, f(x) is a quadratic equation: f(x) = a*x^2 + b*x + c.

The arms of the graph go up, so the leading coefficient of f(x) is positive.

The vertex of f(x) is near (-0.5, -2)

The roots are at x = -2 and x = 1. (intersects the x-axis at two points)

Now, we know that:

g(x) has a positive leading coefficient, and a vertex at (0, 3)

As the leading coefficient is positive, the arms go up, and the minimum value will be the value at the vertex, so the minimum value of g(x) is 3, when x = 0.

As the minimum value of y is 3, we can see that the graph never goes to the negative y-axis, so it never intersects the x-axis.

so:

f(x) intersects the x-axis at two points

g(x) does not intersect the x-axis.

The correct option is A.

If m∠c=11x+85/3 and x=13 then what type of angle is c please help me with this

GuDViN [60]

Answer:

Acute angle

Step-by-step explanation:

Given that m<C = $\frac{11x + 85}{3}$ , to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.

m<C = $\frac{11x + 85}{3}$

m<C = $\frac{11(13) + 85}{3}$

m<C = $\frac{228}{3}$

m<C = 76°

Acute angles are less than 90°.

m<C is less than 90°, therefore it is an acute angle.
