If f(x)=2x-3 then find the expression given by f(a+h)-f(a)/h
​

Answer: 170

Step-by-step explanation: Angle G and Angle H are consecutive angles, meaning they both add up to 180 degrees. Thus, if 10 is the value of Angle G, Angle H must be 170.

Answer:

Its d

Step-by-step explanation:

because you square 10 and you get 100 and you have to multiply 6 with 100 which is 600 and then you multiply the 3.14 which gives you 1,884

Answer:

-x + 1

Step-by-step explanation:

f(x) = 2x + 3

g(x) = 3x + 2

we want to find (f-g)(x)

(f-g)(x) is the same as saying f(x) - g(x)

f(x) - g(x) = (2x + 3) - (3x + 2)

==> remove parenthesis and apply negative sign

f(x) - g(x) = 2x + 3 - 3x - 2

==> combine like terms

f(x) - g(x) = -x + 1

Put values

Answer:

f(3) = 68

Step-by-step explanation:

Given:

[tex]\sf f(1)=2[/tex]

[tex]\sf f(n) = f(n-1)^2+4[/tex]

[tex]\sf \implies f(2) = f(1)^2+4[/tex]

[tex]\sf \implies f(2) = 2^2+4=8[/tex]

[tex]\sf \implies f(3) = f(2)^2+4[/tex]

[tex]\sf \implies f(3) = 8^2+4=68[/tex]

To find the area of an irregular shape (in general)

 ⇒ is best to split it into different regular shapes

   ⇒ (in this case), let's split into a half-circle and a square

Area of the half-circle:

 ⇒ half the area of a circle ([tex]\pi r^2[/tex])

     ⇒ Area of half-circle = [tex]\frac{1}{2}\pi r^2[/tex]

    Area of Half Circle = [tex]\frac{1}{2}\pi (8.5)^2 = 113.5m^2[/tex]

Area of square

  ⇒ length * width

     ⇒ Area of Square = 17 * 17 = 289[tex]m^2[/tex]

Total Area = 113.5 + 289 = 402.5 ≈ 402[tex]m^2[/tex]

Hope that helps!

Answer:

A = 240 units²

Step-by-step explanation:

the area (A) of a regular polygon is

A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )

here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then

A = [tex]\frac{1}{2}[/tex] × 48 × 10 = 24 × 10 = 240 units²

Answer:

Step-by-step explanation:

Preliminary task

Draw a regular octagon.

Draw a perpendicular from the side's midpoint to the center. (That is the  apothem).

Draw two radii from the center of the side to the center of of the octagon. The endpoints of these two radii is the endpoints of the octagon's side.

The octagon has 8 such triangles.

Area one triangle

Area = 1/2 * side *  apothem

side = 6

apothem = 10

Area = 1/2 6 * 10

Area = 30

Area of 8 such triangles.

Area = 8 * area of 1 triangle

area 1 triangle = 30

Area of 8 such triangles = 30*8 = 240

[tex]\frac{1}{2}[/tex] × 2,175 = 1,087.5 < 2,175

Answer:

C

Step-by-step explanation:

Since the angles in a triangle add to 180 degrees, the third angle is 180-70-45=65 degrees

Answer:

X=121, y=59, w=59, z=53

Step-by-step explanation:

To find w, we know that the interior angles of a triangle are 180°. Thus ↓

180-31-90=59

For y, we know that y and w are opposite angles. Therefore, y = w = 59.

To find x, we know that there is a one straight line, so therefore we use ↓

180-59=121

Lastly, to find z, we know that the interior angles of a triangle are 180°. Thus ↓

180-59-68=53

Answer:

d = 60t

Step-by-step explanation:

distance = d

time = t

every hour 60 miles are travelled so its 60t

referring to 60*time eg 60*3 = 180

Answer:

m=1

Step-by-step explanation:

(2,5);(−6,−3)

(x1,y1)=(2,5)

(x2,y2)=(−6,−3)

Use the slope formula:

m=

y^2−y^1

x^2−x^1

=

−3−5/−6−2

=

−8/−8

=1

Answer:

m=1

Answer:

[tex]\boxed{\sf{1}}[/tex]

Step-by-step explanation:

To solve this problem, you have to use a slope formula.

Slope formula:

[tex]\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{Rise}{run} }[/tex]

[tex]\sf{y_2=(-3)}\\\\\sf{y_1=5}\\\\\sf{x_2=(-6)}\\\\\sf{x_1=2}[/tex]

Rewrite the problem down.

[tex]\sf{\dfrac{(-3)-5}{(-6)-2} }[/tex]

Solve.

[tex]\sf{\dfrac{(-3)-5}{(-6)-2}=\dfrac{-8}{-8}=\boxed{\sf{1} }[/tex]

Answer:

m=117

Step-by-step explanation:

So this area is 360 degrees

What you can see the 68 degrees is congruent to its opposing side so we can eliminate those. 360 - 126= 234

We can see m is congruent to U

234/2=117

m=117

Answer:

81π

Step-by-step explanation:

To find the area of a circle, the formula is πr^2

r=radius, and radius is half the diameter, so it is 9.

Plug the radius into the formula to get 81π

(9^2*π)

Answer: I believe the answer is C. (-3,4)

Step-by-step explanation:

Answer:

It's B

-10 + 6

Step-by-step explanation:

Here, we gotta use the distributive property.

the -2 will distribute to the 5, which will make the -10

then, the -2 will also distribute to the -3 (the minus is the negative) which will make the 6

So, that should give you the -10 + 6, which is B

hope this helped :)

Answer:

Step-by-step explanation:

Use the distributive property.

Distributive property:

→ A(B+C)=AB+AC

→ -2(5-3)

Multiply.

→ -2*5=-10

→ -2*3=-6

Rewrite the problem down.

→ = -10+6
