Answer:

30 inches squared.

Step-by-step explanation:

Area of triangle is equal to base times height divided by 2.

$\frac{bh}{2}$

$\frac{10 \times 6}{2}$

$\frac{60}{2}=30$

Answer:

The answer is 30 inch^2.

Step-by-step explanation:

Okay, so to find the area just do the regular: length times width

- 6 time 10 = 60.

However, this is a triangle so u have to divide it by 2.

60/2 = 30 in.^2

Answer:

D. y = 3(1/3)x

Step-by-step explanation:

if x = -1

y = 9

A. y = (1/3) -¹ = 3 X

B. y = (1/3) -¹ + 2 = 5 X

C. y = (1/3) -¹ + 3 X

D. y = 3(1/3) -¹ = 9 ✓

So D is the answer

Brainliest for help! Sketch a graph of the function y =sin(x) + 2

diamong [38]

Answer:

The parent sine graph $y=sin(x)$ has a range of -1 ≤ y ≤ 1

It crosses the x-axis x = 0° ± 180°n

The maximum points occur when x = 90° ± 360°n and y = 1

The minimum points occur when x = 270° ± 360°n and y = -1

The sketch the graph of function $y=sin(x)+2$ we simply move the graph of $y=sin(x)$ up 2 units.

So this means it will have a range of 1 ≤ y ≤ 3

It no longer crosses the x-axis.

The maximum points occur when x = 90° ± 360°n and y = 3

The minimum points occur when x = 270° ± 360°n and y = 1

Attached diagram

The parent function $y=sin(x)$ is shown in grey (dashed line)

The function $y=sin(x)+2$ is shown in red.

A student repeatedly measures the mass of an object using a mechanical balance and gets the following values: 560 g, 562 g, 556

MrRissso [65]

Answer: 2.76 g

Step-by-step explanation:

The formula to find the standard deviation:-

$\sigma=\sqrt{\dfrac{\sum(x_i-\overline{x})^2}{n}}$

The given data values : 560 g, 562 g, 556 g, 558 g, 560 g, 556 g, 559 g, 561 g, 565 g, 563 g.

Then, $\overline{x}=\dfrac{\sum_{i=1}^{10} x_i}{n}\\\\\Rightarrow\ \overline{x}=\dfrac{560+562+556+558+560+556+559+561+565+563}{10}\\\\\Rightarrow\ \overline{x}=\dfrac{5600}{10}=560$

Now, $\sum_{i=1}^{10}(x_i-\overline{x})^2=0^2+2^2+(-4)^2+(-2)^2+0^2+(-4)^2+(-1)^2+1^2+5^2+3^2\\\\\Rightarrow\ \sum_{i=1}^{10}(x_i-\overline{x})^2=76$

Then, $\sigma=\sqrt{\dfrac{76}{10}}=\sqrt{7.6}=2.76$

Hence, the standard deviation of his measurements = 2.76 g

PLEASE HELP ASAP! WILL GIVE BRAINLEIST! Find the area of the shaded region. Use pi = 3.14

Semmy [17]

Answer:

Step-by-step explanation:

Square

The side length of the square = 8 cm

The area of the square = s^2

The area of the square = 8^2 = 64

Circle

r = d/2

r = 8/2

r = 4

Area of the circle = pi r^2

Area of the circle = 3.14 * 16

Area of the circle = 50.24

Shaded Area

Area of the Shaded area = area Square - Area Circle

= 64 - 40.24

= 23.76
