hello :

sinx = - -√2/2        0°≤x≤360°

x = 225°

x= 315°

The value of x in this equation is 315°

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here:

Sinx= -√2/2

x     =sin⁻¹( -√2/2)

x      = -45°

Therefore positive angle of x is given by 360-45=315°

Hence, The value of x in this equation is 315°

Answer:

(-1/2,1/2)

Step-by-step explanation:

We have  the two endpoints

(-3,-2) and ( 2,3)

To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2

(-3+2)/2 = -1/2 =-1/2

To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2

(-2+3)/2 = 1/2

The midpoint is (-1/2,1/2)

From 18 wolves to 27 wolves, what was the increase? 27 - 18 is 9, so the increase was 9.

How much of 18 is 9? 9 / 18 is equal to 1 / 2, which is 0.5. To make 0.5 a percent we multiply by 100.

0.5 times 100 is 50%.

[tex]5\,x\,y\,(-x+2-3y)[/tex]

Step-by-step explanation:

Always proceed by first extracting all common factors to all terms:

Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:

[tex]-5x^2y+10xy-15xy^2\\5\,x\,y\,(-x+2-3y)[/tex]

Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.

2ya and 2yb where a and b have no common factors and a and b are polynomaals

a=(x+2)(x+3)

b=(x+4)(x+5)

no common factors betwen a and b

so

2ya=2y(x+2)(x+3)=2yx²+10xy+12y

Question:

Triangle ABC is a right triangle

The length of BC is 5 units.

The area of ABC is ______ square units.

Cordinates are given below.

A(-9, 10)

B(7, -2)

C(4,-6)

Answer:

50 square units

Step-by-step explanation:

Image to question is attached.

Given:

Length of BC = 5 units

Coordinates:

A = (-9, 10)

B= (7, -2)

C = (4, -6)

Let's take BC as base, and AB as height.

Since we know length of BC, let's find length of AB.

Length of AB =

[tex] \sqrt{(-9 - 7)^2 +(10 + 2)^2 [/tex]

[tex] = \sqrt{(256)+(144) [/tex]

= 20.

Therefore, the area of triangle ABC [tex] = \frac{1}{2} b*h [/tex]

[tex] = \frac {1}{2} * 5 * 20 [/tex]

= 50 square units.

Answer: 50

Step-by-step explanation:

Answer:

201

Step-by-step explanation:

The situation can be represented by the formula N(t)=11e(−kt) where t represents time in minutes and k is a constant.

64 - (3y + 8y + y) / 40 = 37

Simplify 3y + 8y + y

64 - 12y / 40 = 37

Add 12y / 40 to both sides and subtract 37

27 = 12y / 40

Multiply both sides by 40

1080 = 12y

Divide both sides by 12

90 = y

Answer:

y=90

Step-by-step explanation:

Collect the like terms first (3y, 8y, and y) and add them together, which gives you 12y. Equation looks like this so far 64-12y/40=37

Divide the -12 by 40, which can be reduced to -3/10.Equation so far: 64-3/10y=37

Multiply each side by 10 to cancel out the 10 in -3/10y. Equation so far: 640-3y=370

Use inverse operations to move the 640 with the 370. Equation so far: 3y=370-640

Subtract 640 from 370, which gives you -270. Then you'll have -3y=-270 and divide both sides by -3.

Answer: 54 minutes

Step-by-step explanation: Given that Tom spent 1/10 hour less time than normal exercising.

Let the normal exercising hour = H

Tom spent 1/10 hour less time than normal exercisin. That is

Tom spent = H - 1/10H

Tom spent = 9/10 hours

The much time Tom spent exercising last week will be

9/10 × 60 = 54 minutes

The volume is 201√2 and the surface area is 274.

To solve the problem, we need to calculate both the volume and the surface area of the frustum of a regular square pyramid with given dimensions.

First, let's find the volume of the frustum. The volume V of a frustum of a pyramid can be calculated using the formula:

[tex]\[ V = \frac{1}{3}h(B_1 + B_2 + \sqrt{B_1B_2}) \][/tex]

where h is the height of the frustum, [tex]\( B_1 \)[/tex] is the area of the smaller base, and [tex]\( B_2 \)[/tex] is the area of the larger base.

Given that the edges of the bases are 5 and 9, the areas of the bases are:

[tex]\[ B_1 = 5^2 = 25 \] \[ B_2 = 9^2 = 81 \][/tex]

To find the height , we can use the Pythagorean theorem on the right triangle formed by the slant height, half of the difference of the base edges, and the height of the frustum:

[tex]\[ h = \sqrt{s^2 - \left(\frac{a_2 - a_1}{2}\right)^2} \][/tex]

where s is the slant height, [tex]\( a_1 \)[/tex] is the edge of the smaller base, and [tex]\( a_2 \)[/tex] is the edge of the larger base. Plugging in the given values:

[tex]\[ h = \sqrt{6^2 - \left(\frac{9 - 5}{2}\right)^2} = \sqrt{36 - 4} = \sqrt{32} = 4\sqrt{2} \][/tex]

Now we can calculate the volume:

[tex]\[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot (25 + 81 + \sqrt{25 \cdot 81}) \] \[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot (106 + \sqrt{2025}) \] \[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot (106 + 45) \] \[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot 151 \] \[ V = \frac{1}{3} \cdot 604\sqrt{2} \] \[ V = 201\sqrt{2} \][/tex]

Next, let's calculate the surface area of the frustum. The surface area \( A \) of a frustum is the sum of the areas of the two bases and the area of the lateral surface:

[tex]\[ A = B_1 + B_2 + A_{\text{lateral}} \][/tex]

The lateral surface area [tex]\( A_{\text{lateral}} \)[/tex] can be found using the formula:

[tex]\[ A_{\text{lateral}} = \frac{1}{2}(P_1 + P_2)s \][/tex]

where [tex]\( P_1 \)[/tex] and [tex]\( P_2 \)[/tex] are the perimeters of the smaller and larger bases, respectively, and s is the slant height. Since the pyramid is regular and square:

[tex]\[ P_1 = 4a_1 = 4 \cdot 5 = 20 \] \[ P_2 = 4a_2 = 4 \cdot 9 = 36 \][/tex]

Now we can find the lateral surface area:

[tex]\[ A_{\text{lateral}} = \frac{1}{2}(20 + 36) \cdot 6 \] \[ A_{\text{lateral}} = \frac{1}{2} \cdot 56 \cdot 6 \] \[ A_{\text{lateral}} = 28 \cdot 6 \] \[ A_{\text{lateral}} = 168 \][/tex]

Adding the areas of the bases:

[tex]\[ A = 25 + 81 + 168 \] \[ A = 274 \][/tex]

Therefore, the volume and surface area of the frustum are:

[tex]\[ {V = 201\sqrt{2}} \] \[ {A = 274} \][/tex]
