Answer:

A right triangle has legs that are 10.1 inches and 12.2 inches long. What is the approximate length of the hypotenuse?

6.8 inches

15.8 inches

22.3 inches

125.5 inches

B. 15.8 inches  is the correct option

The distance between the two points is approximately 29.70 m. The polar coordinates of the points are approximately (24.20 m, 1.46 radians).

To find the distance between two points in the Cartesian coordinate plane, we can use the distance formula.

The distance between the points (2.00, 24.00) m and (23.00, 3.00) m is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values, we get:

d = sqrt((23.00 - 2.00)^2 + (3.00 - 24.00)^2)

d = sqrt(441 + 441)

d = sqrt(882)

d ≈ 29.70 m

The polar coordinates of a point (x, y) can be found using the formulas:

r = sqrt(x^2 + y^2)

p = atan2(y, x)

Plugging in the values, we get:

r = sqrt(2.00^2 + 24.00^2)

p = atan2(24.00, 2.00)

r ≈ 24.20 m

p ≈ 1.46 radians

Answer:

The factored form is

[tex]x^2-7x+2x-14=(x+2)(x-7)[/tex]

Step-by-step explanation:

Given the trinomial

[tex]x^2-5x-14[/tex]

we have to factor the above trinomial.

[tex]x^2-5x-14[/tex]

By middle term splitting method

[tex]x^2-7x+2x-14[/tex]

Taking x common from first two terms and 2 from last two terms

[tex]x(x-7)+2(x-7)[/tex]

[tex](x+2)(x-7)[/tex]

which are required factors.

Hence, option B is correct.

Step-by-step explanation:

The volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Suppose the base of the pyramid has length = L units and width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (L × B × H) / 3

V = (Base area x H) / 3

The volume of a pyramid varies jointly with the base area of the pyramid and its height.

The volume of one pyramid is 24 cubic inches when its base area is 24 square inches and its height is 3 inches.

Then the volume of a pyramid with a base area of 15 square inches and a height of 7 inches will be

V = (15 x 7) / 3

V = 35 cubic inches

Hence, the volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.

A conditional statement that correctly describes each Venn diagram include the following;

I. If m∠A = 40, then it represent acute angles.

II. If 2x = 4, then x is equal to 2.

In Mathematics, a conditional statement is a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, a conditional statement typically has the form "if P then Q."

Where:

P and Q represent sentences or statements.

Part I.

Based on the Venn diagram shown in the image above, we can logically deduce the following conditional statement;

"If m∠A = 40, then it represent acute angles."

All acute angles are less than 90 degrees.

Part I.

Based on the Venn diagram shown in the image above, a conditional statement that correctly describes it can be written as follows;

"If 2x = 4, then x is equal to 2."

Proof:

2x = 4

x = 4/2

x = 2

The side that is parallel to side s is side q. The equation of side q is: y = -x + 9.

We can represent the equation of a line as, y = mx + b, where m is the slope of the line and b is the y-intercept.

The side that is parallel to side s is q.

Slope (m) of q = change in y / change in x = (6 - 3) / (3 - 6) = 3/-3 = -1.

Substitute m = -1 and (3, 6) = (a, b) into y - b = m(x - a):

y - 6 = -1(x - 3)

y - 6 = -x + 3

y = -x + 3 + 6

y = -x + 9

Equation of the side that is parallel to side s is: y = -x + 9.

Answer:  The required co-ordinates of the point are (0.5, 5.5).

Step-by-step explanation:  We are given to find the co-ordinates of the point that splits CD in half if point C is located at (-2,4) and point D is located at (3,7).

The point that splits the line segment CD in half will be the mid-point of the segment CD.

We know that

the co-ordinates of the mid-point of a line segment with endpoints (a, b) and (c, d) are given by

[tex]\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]

Therefore, the co-ordinates of the given point that splits CD in half are given by

[tex]\left(\dfrac{-2+3}{2},\dfrac{4+7}{2}\right)=\left(\dfrac{1}{2},\dfrac{11}{2}\right)=(0.5,5.5).[/tex]

Thus, the required co-ordinates of the point are(0.5, 5.5).

Answer:

[-8,2]

Step-by-step explanation:

We are given that the function f(x) is transformed to the function g(x), where,

[tex]f(x) =-5 \cos 2x[/tex] and [tex]g(x) =-5 \cos 2x-3[/tex].

Since, the range of [tex]\cos x[/tex] is [-1,1].

Thus, the range of [tex]a\cos bx[/tex] is {-a,a].

So, the range of [tex]f(x) =-5 \cos 2x[/tex] is [-5,5].

As, we are translating the function f(x) 3 units downward to get g(x).

The graph of the function is shifted 3 units down.

So, the range of g(x) will be [-5-3,5-3] = [-8,2].

Hence, the range of [tex]g(x) =-5 \cos 2x-3[/tex] is [-8,2].

The volume the hemisphere is 56. 55 cubic feet
