write the product in standard form (2x + 5) ^2

**Answer:**

4x^2+20x+25

**Step-by-step explanation: **

(2x+5)^2 = (2x+5) (2x+5)

Using the foil method : 2x(2x) = 4x^2

(2x) (5) = 10x

(2x) (5) = 10x

5 (5) = 25

**Answer:**

Deduction is inference deriving logical conclusions from premises known or assumed to be true, with the laws of valid inference being studied in logic. Induction is inference from particular premises to a universal conclusion.

**Step-by-step explanation:**

Work out m and c for the line: y = 7 − x

You see it’s dfuunny how I have no clue wigs I could tho xx

The **line **y = 7 − x has a **slope**(**m**) of - 1 and y-intercept **b **is 7.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in **slope-intercept** form is

**y = mx + b**.

Where slope = **m** and **b **= y-intercept.

the slope is the **rate **of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, an **equation **of a line** y = 7 - x**.

We can **rearrange** this in the form of slope-intercept form which is

**y = mx + b**.

y = - x + 7.

y = (-1)x + 7.

The slope (m) of this line is - 1 and the y-intercept(b) is 7.

Find the Area of the figure below, composed of a rectangle with a semicircle

removed from it. Round to the nearest tenths place.

**Answer:**

**Area of the figure = 25.7 units²**

**Step-by-step explanation:**

Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD

Area of the rectangle ABCD = Length × Width

= BC × AB

= 8 × 4

= 32 units²

Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Here, r = radius of the semicircle

r = [tex]\frac{\text{Diameter}}{2}[/tex]

r = [tex]\frac{1}{2}(CD)[/tex]

r = [tex]\frac{4}{2}[/tex]

r = 2 units

Therefore, area of the semicircle = [tex]\frac{1}{2}\pi (2)^2[/tex]

= 2π

= 6.28 units²

**Area of the given figure** = 32 - 6.28

= 25.72 units²

≈ **25.7 units²**

**Answer:**

Over 300 students did not support start time after 8:00am

**Step-by-step explanation:**

**Given**

[tex]N = 600[/tex] --- population

[tex]n = 40[/tex] --- sample

See attachment for dataset

**Required [True/False]**

**Over 300 wants start time after 8:00am**

First, we calculate the number of samples that wants start time after 8:00am

[tex]x = 8:30am\ start + 9:00am\ start[/tex]

**For sample 1**

[tex]x_1 = 18[/tex]

**The corresponding value of x1 in the overall population is:**

[tex]X_1 = \frac{x_1}{n} * N[/tex]

[tex]X_1 = \frac{18}{40} * 600[/tex]

[tex]X_1 = \frac{18 * 600}{40}[/tex]

[tex]X_1 = \frac{10800}{40}[/tex]

[tex]X_1 = 270[/tex]

**For sample 2**

[tex]x_2 = 19[/tex]

**The corresponding value of x2 in the overall population is:**

[tex]X_2 = \frac{x_2}{n} * N[/tex]

[tex]X_2 = \frac{19}{40} * 600[/tex]

[tex]X_2 = \frac{19* 600}{40}[/tex]

[tex]X_2 = \frac{11400}{40}[/tex]

[tex]X_2 = 285[/tex]

**None of X1 and X2 is greater than 300.**

**Hence, over 300 students did not support start time after 8:00am**

None of X1 and X2 is **greater **than 300. so, over 300 **students **did not **support **start **time **after 8:00 am.

The **population **is 600 and the **sample **is 40.

The **population **of **inference **refers to the **population **(or universe) to which the **results **from a sample **survey **are meant to generalize.

Over 300 **students **did not **support **start **time **after 8:00 am

For **sample **1

The corresponding value of x1 in the overall **population **is:

[tex]\rm X_{1} =\frac{x_{1} }{n} \times N\\\rm X_{1} =\frac{18}{40} \times 600\\\rm X_{1} =\frac{10800}{40}\\ \rm X_{1} =270\\[/tex]

For **sample **2

[tex]\rm x_{2} =19[/tex]

**Given:**

In triangle EFG, [tex]EF=10\sqrt{2}, m\angle G=90^\circ,m\angle E=60^\circ[/tex].

**To find:**

The measures of FG, EG and angle F.

**Solution:**

In triangle EFG,

[tex]m\angle E+m\angle F+m\angle G=180^\circ[/tex] [Angle sum property]

[tex]60^\circ+m\angle F+90^\circ=180^\circ[/tex]

[tex]m\angle F+150^\circ=180^\circ[/tex]

[tex]m\angle F=180^\circ-150^\circ[/tex]

[tex]m\angle F=30^\circ[/tex]

In a right angle triangle,

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin E=\dfrac{FG}{EF}[/tex]

[tex]\sin (60^\circ)=\dfrac{FG}{10\sqrt{2}}[/tex]

[tex]\dfrac{\sqrt{3}}{2}\times 10\sqrt{2}=FG[/tex]

[tex]5\sqrt{6}=FG[/tex]

Similarly,

[tex]\sin F=\dfrac{EG}{EF}[/tex]

[tex]\sin (30^\circ)=\dfrac{EG}{10\sqrt{2}}[/tex]

[tex]\dfrac{1}{2}\times 10\sqrt{2}=EG[/tex]

[tex]5\sqrt{2}=EG[/tex]

**Therefore, the required measures are [tex]FG=5\sqrt{6}, EG=5\sqrt{2}, m\angle F=30^\circ[/tex].**

Naitik exercised for

2/3 hours ,while Aryan exercised for

3/4

hours.Who

exercised for a longer time? step by step answer

=======================================================

Explanation:

Use your calculator to convert each fraction into decimal form

2/3 = 0.67 approximately

3/4 = 0.75 exact

The decimal 0.75 is larger than 0.67, in which we can think of it like saying "75 is larger than 67".

So 0.67 < 0.75 which leads to 2/3 < 3/4.

**Aryan spent more time exercising.**

--------------

We could stop there, but if you wanted to know how much longer he spent exercising, then we subtract the two fractions to get

3/4 - 2/3

9/12 - 8/12

(9-8)/12

1/12

Aryan spent 1/12 of an hour longer exercising compared to Naitik

1/12 hour = (1/12)*60 = 60/12 = 5 minutes

He spent 5 extra minutes exercising.

----------------

Notes:

2/3 hours = (2/3)*60 = 40 minutes3/4 hours = (3/4)*60 = 45 minutes45-40 = 5 extra minutes of exercise3. Write an equation of the line that passes through (2, 3) and is perpendicular to y=-1/2x - 5

**Answer:**

y=2x-1

**Step-by-step explanation:**

A line that is perpendicular has a slope that is a negative reciprocal of the given equation. The slope of the given equation is -1/2, so the negative reciprocal would be 2.

Then, using slope-intercept form, plug in the point values (2,3) into the equation and solve for b.

y=mx+b

y=2x+b

3=2(2)+b

-1=b

Therefore the equation is y=2x-1

The mirror has a frame. The diameter of the mirror with the frame is 17 inches. To the nearest hundredth, what is the area of the mirror with the frame? Use 3.14 for π.

**Answer:**

the diameter: 17inches

so the radius is: 8.5 inches

the formula for calculating a circle's area:

r×r×π

so:

8.5×8.5×3.14= 226.865

The required to the nearest hundredth, the **area **of the **mirror **with the frame is approximately 254.34 square inches.

The **surface area **of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the **exterior **of a 3D **shape**.

We know that the diameter of the mirror with the frame is 17 inches, which means that the radius of the mirror is half of that or 8.5 inches.

To find the area of the mirror with the frame, we need to subtract the area of the frame from the area of the circle. The area of the circle is:

[tex]A_{circle} = \pi r^2A_{circle} = 3.14 \times (8.5)^2A_{circle} \approx 226.98\ \ \ square inches[/tex]

To find the area of the frame, we need to subtract the area of the inner circle (the mirror) from the area of the outer circle (the frame). The radius of the inner circle is 8.5 inches, and the radius of the outer circle is half of the diameter of the mirror, or 8.5 + (1/2) = 9 inches.

The area of the frame is:

[tex]A_{{frame}} = \pi (9^2) - \pi (8.5^2)A_{frame} = 3.14 \times (81 - 72.25)A_{frame} \approx27.36 \ \ \ square inches[/tex]

Now we can find the area of the mirror with the frame by adding the area of the circle and the area of the frame:

[tex]A_{mirror\ with \ frame} = A_{circle} + A_{frame}A_{mirror\ with \ frame} \approx 226.98 + 27.36A_{mirror\ with \ frame} \aprrox 254.34 \ \ \ square inches[/tex]

Therefore, to the nearest hundredth, the **area **of the **mirror **with the frame is approximately 254.34 square inches.
