how do you answer this angle problem?

Answer:

Mtan=1-2a

Step-by-step explanation:

Mtan=lim h->0[5-(a+h)-(a+h)^2-(5-a-a^2)/h

=lim h->0[5-a-h-a^2-2ah-h^2-5+a+a^2]/h

=lim h->0[h-2ah-h^2+5-5-a+a-a^2+a^2]/h

=lim h->[h-2ah-h^2 +0+0+0]/h

=lim h->o[h(1-2a-h)/h

=lim h->0 (1-2a-h)

=1-2a-0

=1-2a

Mtan=1-2a.

Answer:

52 ft

Step-by-step explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:

Answer:

52m

Step-by-step explanation:

Area of the square floor = 169 m²

So,

Length of each side of floor = √169 = 13m

Hence ,

Perimeter of the kitchen = 13 × 4 = 52m

Answer:

h = 5x + 3

Step-by-step explanation:

I believe the volume should be [tex]5x^{3} + 13x^{2} + 6x[/tex]  in the question. Based on the correction:

[tex]V = 5x^{3} + 13x^{2} + 6x\\A = x^{2} + 2x\\V = A.h\\h = \frac{V}{A} = \frac{5x^{3} + 13x^{2} + 6x}{x^{2} + 2x} = \frac{x(5x^{2}+13x+6}{x(x+2)}=\frac{5x^{2}+13x+6}{x+2} = \frac{(x+2)(5x+3)}{x+2} = 5x+3[/tex]

Answer:

31.25 kg of flour is needed to make 50 cakes

Step-by-step explanation:

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.

Flour needed to make 4 cakes = 2.5 kg

Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg

Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]

                                                      = 31.25 kg

So, 31.25 kg of flour is needed to make 50 cakes

Answer:

about 7 cups

Step-by-step explanation:

if he uses 2 cups for 18 cookies, then he uses 1 cup for 9 cookies. the closest whole number you can get is 63 (9 x 7) so he will need about 7 cups of flour for 60 cookies. hope this helps! :)

Answer:

a) y= ⅔x -4

b) -4

Step-by-step explanation:

Please see the attached pictures for the full solution.

Answer:

First, let's explain the transformations in a general way:

Vertical shift.

If we have a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

This will move the graph of f(x) up or down a distance of N units.

if N is positive, then the shift is upwards

if N is negative, then the shift is downwards.

Horizontal shift.

If we have a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

This will move the graph of f(x) to the right or left a distance of N units.

if N is positive, then the shift is to the left

if N is negative, then the shift is to the right.

Horizontal dilation/contraction.

For a function f(x), an horizontal contraction dilation is written as:

g(x) = f(k*x)

where:

k is called the "scale factor"

If k < 1, then the graph "dilates" horizontally.

if k > 1, then the graph "contracts" horizontally.

Now, in this problem we have:

f(x) = log(x)

And the transformed function is:

g(x) = f(0.25*(x - 5)) + 3

Then, the transformations that take place here are, in order:

Vertical shift of 3 units up:

g(x) = f(x) + 3.

Horizontal shift of 5 units to the right:

g(x) = f(x - 5) + 3

Horizontal dilation of scale factor 0.25

g(x) = f( 0.25*(x - 5)) + 3

replacing f(x) by log(x) we have

g(x) = log(0.25*(x - 5)) + 3.

slope intercept form:

y = mx + b

m = slope

b = y-intercept

the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.

y = mx + 4

the slope is technically the rate of change (rise over run) bewteen points.

If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1

y = 1x +4

this could also be:

y = x + 4

(because the 1 is invisible but still there)

Step-by-step explanation:

the slope always goes in front of the x and then the y-intercept goes after.

Answer:

5/2

Step-by-step explanation:

10 multiplied by 5/2 gives us 25, so the scale factor is 5/2.

t is 35 for  x+y= 7 and 7x + ty = 77, and the  value of t is 7 for x+y=7 and 7x+ty=49

Two or more expressions with an Equal sign is called as Equation.

Given equations are x+y= 7..(1)

7x + ty =77

We need to find value of t.

Multiply equation 1 with 7

7x+7y-7x-ty=49-77

y(7-t)=-28

7-t=-28

-t=-28-7

-t=-35

t=35

Hence the value of t is 35

Now for equations x+y=7

7x+ty=49

7x+7y-7x-ty=49-49

7y-ty=0

y(7-t)=0

7-t=0

t=7

Hence the value of t is 7

Therefore, t is 35 for  x+y= 7 and 7x + ty = 77, and the  value of t is 7 for x+y=7 and 7x+ty=49
