Answer:

a = −1 / 2 b^3 + 1 / 2 bh

Step-by-step explanation:

1 )

h = 2a / b^1 + b^2

2 ) Multiply both sides by b.

bh = b^3 + 2a

3 ) Flip the equation.

b^3 + 2a = bh

4 ) Add -b^3 to both sides.

b^3 + 2a + −b^3 = bh + −b^3

2a = −b^3 + bh

5 ) Divide both sides by 2.

2a / 2 = −b^3 + bh / 2

a = −1 / 2 b^3 + 1 / 2 bh

The value x from given triangle FGH of x is 11.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the given figure, ∠G=2x+8, ∠H=65° and ∠JFG=9x-4.

Here, ∠JFG=∠G+∠H

⇒ 9x-4=2x+8+65

Step-by-step explanation:

a) The co-efficient of x⁴y³ = -241920

b) The coefficient of x²y⁷ =  900

What Does an Expression Coefficient Mean?

The expansion is given by the following formula:

(a + b)ⁿ = Σⁿₓ=₀(ⁿₓ) aⁿ⁻ˣ bˣ, where

(ⁿₓ) = n! / (n-x)! k! and n! = 1.2..3.....n.

a) (-3x+4y)⁷ = ⁷C₀ (-3x)⁷(4y)⁰ + ⁷C₁ (-3x)⁶(4y)¹ + ⁷C₂ (-3x)⁵(4y)¹ + ⁷C₃ (-3x)⁴(4y)³ + ⁷C₄ (-3x)³(4y)⁴ + ⁷C₅ (-3x)²(4y)⁵ + ⁷C₆ (-3x)¹(4y)⁶ + ⁷C₇ (-3x)⁰(4y)⁷

The co-efficient of x⁴y³ = 35x - 27x³ * 256y⁴

The translation from the triangle ABC to triangle A'B'C' is 3 units right and 2 units up.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Given that,

The coordinates of triangle ABC are A(-3, 1), B(-1, 2) and C(1, 1)

The coordinates of triangle A'B'C' are A'(0, 3), B'(2, 4) and (4, 3).

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

A(-3, 1)→A'(-3+3, 1+2)

B(-1, 2)→B'(-1+3, 2+2)

C(1, 1)→C'(1+3, 1+2)

Therefore, the translation is 3 units right and 2 units up.

constructing cones a right triangle whose hypotenuse is 23 m long is revolved about one of its legs to generate a right circular cone. radius: 11.5 m height: 23 m volume: 1650.6 m³

The hypotenuse of the triangle is 23 m. This means that the two sides are 11.5 m and 11.5 m. This gives us the radius of the cone.

The height of the cone is the same as the hypotenuse, so the height is 23 m.

The volume of a right circular cone can be calculated using the following formula: V = (πr²h)/3. In this case, the radius is 11.5 m, the height is 23 m, and π = 3.14. Plugging these values into the formula, we get a volume of 1650.6 m³.

V = (πr²h)/3

V = (3.14 × 11.5² × 23)/3

Answer:

option 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0-(-2)}{4-0}[/tex] = [tex]\frac{0+2}{4}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = [tex]\frac{1}{2}[/tex] x - 2

The remainder is 5. To calculate this, first, divide 599 by 9 to get the largest multiple of 9 before 599. 5/9 < 1, so carry the 5 to the tens, 59/9 = 6 r 5, so carry the 5 to the digits. 59/9 = 6 r 5 again, so the largest multiple is 66. Multiply 66 by 9 to get 594, and subtract this from 599 to get 5, the remainder.

Step-by-step explanation:

The equation of the line passing through the points (0, -6) and (7, 4) in slope-intercept form is y = [tex]\frac{10}{7}[/tex]x - 6.

Slope of a line is defined as the tangent of the angle that the line makes with X axis.

Slope, usually denoted by 'm' of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by,

m = (y₂ - y₁) / (x₂ - x₁)

The equation of a line in slope-intercept form is y = mx + b, where b is y intercept and m is the slope.

Here, we have two points (0, -6) and (7, 4).

m = (4 - -6) / (7 - 0) = 10/7

y intercept is the y coordinate of the point where the line touches with the Y axis. x coordinate will be zero there.

We already have such point (0, -6).

So b = -6

Substituting these in slope-intercept form,

y =  [tex]\frac{10}{7}[/tex]x - 6

Hence, the equation of the given line in slope intercept form is y = [tex]\frac{10}{7}[/tex]x - 6.
