Answer:

-1/2 x + 3

Step-by-step explanation:

Answer:

a = 39.2650873379cm

b = 11.5529459767cm

Step-by-step explanation:

a - Use the area of a triangle equation -  1/2 * a * b * Sin(C)

1/2 * 8 * 10 * Sin(79) = 39.2650873379cm

b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)

64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398

c = square root of 6.9396506484 = 11.5529459767cm

Put to however many significant figures / decimal places required.

Answer:

NOT a right triangle

Step-by-step explanation:

IF it is a right triangle, then the Pythagorean theorem would apply

13^2 + 82^2  = 83^2   ?????

169  + 6724  = 6889

6893  = 6889 ?     No...it is NOT a right triangle

Answer:

x = 12 and x = -6

Step-by-step explanation:

First subtract 6x on both sides to get a 2nd degree polynomial equal to zero:

[tex]x^2-6x-72=0[/tex]

To complete the square, the formula is to divide 'b' by 2 and square the result. The general form for a 2nd degree polynomial of the variable 'x' is as follows:

[tex]ax^2+bx+c=0[/tex]

For your case, b = 6. Therefore, the term that must be added and subtracted to our equation is:

[tex](6/2)^2=3^2=9[/tex]

Add and subtract 9 to our equation to get:

[tex]x^2-6x+9-9-72=0[/tex]

The first three terms form a perfect square, we have:

[tex](x^2-6x+9)-9-72=0[/tex]

[tex](x^2-6x+9)-81=0[/tex]

What multiplies to equal 9 but adds to equal -6? That would be -3 and -3. Therefore:

[tex](x-3)^2-81=0[/tex]

Add 81 to both sides to get:

[tex](x-3)^2=81[/tex]

We want to take the square root, but recall a square root has a positive and negative branch. Therefore we have two solutions:

[tex]x-3=9[/tex]

[tex]x-3=-9[/tex]

[tex]x=12[/tex]

[tex]x=-6[/tex]

Answer:

2776 is the surface area.

Step-by-step explanation:

19 x 48 = 912 x 2 = 1824. 7 x 19 = 133 x 2 = 266. 49 x 7 = 343 x 2 = 686.

Answer:

2762

Step-by-step explanation:

The formula is:
2*(width*length+height*lenght+height*width)
2*(19*48+7*48+7*19)

this equals 2762

Answer:

64

Step-by-step explanation:

(-2)^6

6 is an exponent and basically it tells us to multiply the base, -2 by itself 6 times

so (-2)^6 is the same as saying -2 × -2 × -2 × -2 × -2 × -2

-2 × -2 × -2 × -2 × -2 × -2 = 64 so the value of (-2)^6 is 64

Answer:

minus 48 to 90 then divide the answer by 2

Answer:

42°

Step-by-step explanation:

The 2 acute angles in a right triangle add up to 90°

90° - 48° = 42°

Answer:

Step-by-step explanation:

Im not sure what it is but my best bet would be on A because the rest of them all say greater than 0 and you are trying to find the least.

Answer:

n < 0

Step-by-step explanation:

Given that:

A number less than 0

Solve:
Since it saying that A number (n) is less than 0 it means it can't be greater.

From the following answer chioce:

[A] n=0

[B] n greater than n 0

[C] n greater then n with a underscore on the bottom 0

[D] n greater than 0 with a underscore 0​

We can see that [B], [C], and [D] all saying greater than. While only [A] has a equal sign to 0.

I'm guess that [A] meant to be put as n < 0. Since the other are saying greater than. But if not. None of the above are correct.

< → less than

> → greater than

A number less than 0 ⇒ n < 0

Answer:

slope = 1/2

Step-by-step explanation:

Pick two convenient integer coordinates

 I'll use  (0,-1) and (2,0)

slope =   (y1-y2)/(x1-x2) =   (-1-0) / ( 0-2) = 1/2

Answer:

Step-by-step explanation:

The cross sectional area of a basketball would indeed be a circle. The units for surface area would be meters squared. The units meters cubed would be volume. Area is inherently a 2-dimensional problem. Therefore, having 3-dimensional units makes no sense. In your case, the correct answer would be yards squared

Answer:

24

Step-by-step explanation:

when x = 5,

4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)

= 4(3)(2) + 7(3)(0) - 6(2)(0)
= 24

Answer:

Arithmetic sqaure: a + (n-1) * d

              where "a" is the first term, "d" is the common difference

Here given:

a = 10 gallons

d = 5.5 gallons

Solve for first 5 terms:

10 + (1-1) * 5.5 = 10

10 + (2-1) * 5.5 = 15.5

10 + (3-1) * 5.5 = 21

10 + (4-1) * 5.5 = 26.5

10 + (5-1) * 5.5 = 32

first five terms: 10, 15.5, 21, 26.5, 32

General formula

So

The approximate length of "y" from the given diagram is 2.0inches

The formula for calculating the volume of a prism is expressed as:

V = lwh

l is the length

w is the width

h is the height

Given that V =4 cubic inches, hence:

4 = x * x* x

4 = x^3
x = ∛4

x = 1.587

Using the pythagoras theorem;

y^2 =1.587^2 +1.587^2

y^2 = 5.037

y = 2.0in

Hence the approximate length of "y" from the given diagram is 2.0inches

Answer:

A reflection over the x-axis

Step-by-step explanation:

The X-axis is the horizontal line, and if G is the result of F, then figure F going up or down 6 units would make it uneven and it wouldn't look flipped.

Answer:

A, a reflection over the x-axis

Step-by-step explanation:

If you focus on one point of figure G (-5,5) you can apply the reflecting rule over the x-axis (change the y-coordinate's sign and leave the x-coordinate the same) and get the point (-5, -5) which fits the rule.

Answer:

-60 = x

The height of the tree that forms an angle of 64 degrees and point from the tree is 49 feet is 100.46 ft

The situation forms a right angle triangle.

using trigonometric ratios,

tan 64 = opposite / adjacent

Where

Therefore,

tan 64 = h / 49

cross multiply

h = 49 × tan 64

h = 49 × 2.05030384158

h = 100.464888237

h = 100.46 ft
