[tex]x^{2} +y^{2} =29[/tex] circle and [tex]y=x-3[/tex]

[tex]y^{2} =29-x^{2}[/tex]                   [tex]\left ( y \right )^{2}=\left ( x-3 \right )^{2}[/tex]

                                       [tex]y^{2}=x^{2}-6x+9[/tex]

[tex]\Rightarrow x^{2} -6x+9=29-x^{2}[/tex]  

[tex]\Rightarrow 2x^{2} -6x-20=0[/tex]         [tex]\Rightarrow 2x^{2} -3x-10=0[/tex]

[tex]x^{2} -5x+2x-10=0[/tex]       [tex]\Rightarrow x\left ( x-5 \right ) +2\left ( x-5 \right )=0[/tex]

[tex]x=5, \ x=-2[/tex]

[tex]\Rightarrow y=29-25=4\pm 2[/tex]       [tex]\Rightarrow y=29-4=25\pm 5[/tex]

The circle intersects the line at [tex]\left ( 5,2 \right )[/tex] and [tex]\left ( -2,-5 \right )[/tex].

Given -

To find -

Solution -

Area of square = side × side = (60 × 60)m² =

Area of square =3600m²

Hence,

Area of rectangular field = Area of square field = 3600m²

Area of rectangular field = l × b = 3600m²

=> l × 32m = 3600m²

=> l = [tex]\sf{\frac{3600}{32}\:m}[/tex]

=> l = 112.5m

so, the length = 112.5m

Answer:

∠A = 48°, ∠B = 48°, and ∠C = 84°

Step-by-step explanation:

AB = CB                Given

m ∠A = m ∠C      If opposite sides are =, then those opposite angles are =

6(x - 3) = 4(x + 1)

6x - 18 = 4x + 4

2x - 18 =  4

2x = 22

x = 11

m ∠A = 6(11 - 3) = 6(8) = 48°

m ∠C = 4(11+ 1) = 4(12) = 48°  

The sum of the angles in a triangle = 180°

48° + 48° m ∠B = 180°

 96°+ m ∠B = 180°

      84° =  m ∠B

Answer:

D. The graph of y = |x| – 4 is the same as y = |x|.

Step-by-step explanation:

The graph y=|x|-4 is obtained from the graph y=|x| dy moving down 4 units the graph y=|x|  along the y-axis (see, if x=0, then for y=|x|, y=0 and for y=|x|-4, y=-4).

These two graphs have the same form.

Answer:

1.0555135e+58

Step-by-step explanation:

The equation is,  [tex]\rm y = 30(1+0.50)^x[/tex]  101.25 bacteria cells after 3 hours, and 3892 bacteria cells after 12 hours  will be present,

It is given that the sample of bacteria cells in a petri dish increases by 50% every hour, a scientist starts with a sample of 30 bacteria cells.

It is required to find the equation that can be used to determine the number of cells after x hours.

It is defined as increasing an amount by a definite percentage over the span of a time, the original amount increases exponentially.

We know the Exponential Growth equation written as:

[tex]\rm y= a(1+r)^t[/tex]

Where y = total amount,

           a = starting amount

           r = the growth rate/exponential decay rate as a decimal

           t = number of growth periods.

We have a = 30

               r = 50% = 0.50

               t = x

Putting these values in the Exponential Growth equation, we get:

[tex]\rm y = 30(1+0.50)^x[/tex]  this is the equation for Exponential Growth.

If x = 3 hours, then:

[tex]\rm y = 30(1+0.50)^3 \Rightarrow 30(1.50)^3\Rightarrow 30(3.375)\Rightarrow 101.25\\[/tex]

If x = 12 hours, then:

[tex]\rm y = 30(1+0.50)^1^2 \Rightarrow 30(1.50)^1^2\Rightarrow 30(129.746)\Rightarrow 3892.39\approx 3892[/tex]

Thus, the equation that can be used to determine the number of cells after x hours is,  [tex]\rm y = 30(1+0.50)^x[/tex], that 101.25 bacteria cells will be present in the dish after 3 hours, and 3892 bacteria cells will be present after 12 hours.

Step-by-step explanation:

Answer:

16,23,31

Step-by-step explanation:

it is non linear because it it doesn't go up by the same amount of numbers each time however we can see that it goes up by 2 then 3 then 4 then 5 so from this we can infer that it will only go up 6 then 7 then 8 ,10 + 6 + 16 16 + 7 is 23 and 23 + 8 is 31

Answer:40

Step-by-step explanation:

[(√36-4)³]*5

[(6-4)³]*5

(2)³ * 5

= 2*2*2 = 8

8*5 = 40

Answer:   When an inequality shows a multiple of -4 = -8 or -16 then we know it is a parallel line and therefore could be a straight line continuation  - we see -3(1) -(5) = -8  and -3(5) -(1) = -16  therefore (1  -5) and (5  -1) are both ordered pairs

-3 (2) + 2 = -4   shows 2 and  2 are an ordered pair of system    -3 (0) -4 = -4   shows 0 and -4 is an ordered pair of the system

Step-by-step explanation:

-3x + y = - 4   when we +3x  both sides we get       y = 3x - 4    so when y intercept starts in -4 we an assume if x is positive and as x  is top heavy and not equal to 1 we have a fraction  x = (y + 4) / 3   and the only thing we hanged to find this fraction value for x was to eliminate 3 and separate x through dividing by x   to see other coordinates  see attachment for ordered pairs by seeing each coordinate on the graph

The new equation will be [tex]y=-1.5x+75[/tex]

Since the height at 0 seconds will be 75, it means that 15 has been added to the height at each time instant.

As a result, the gradient will remain [tex]-1.5[/tex], but the y-intercept will become 75. Therefore the equation will only change at the intercept.

The new equation will be [tex]y=-1.5x+75[/tex]

Answer:

B

Step-by-step explanation:

Since x= −4 is a vertical line, the slope is undefined.

Answer:

B.) Undefined

Step-by-step explanation:

By graphing the equation, it will form a vertical line. This is an undefined slope.

(0, -5)

Step-by-step explanation:

Since we are given the slope and a point on the line, we can use these to write the point-slope form of the equation of the line, which looks this this:

[tex]y - y_1 = m(x - x_1)[/tex]

where [tex](x_1, y_1)[/tex] is the point on the line and m is the slope. So the equation has the form

[tex]y - 4 = 3(x - 3)[/tex]

To find the y-intercept, set x = 0 to get

[tex]y - 4 = 3(0 - 3) \Rightarrow y - 4 = -9[/tex]

Solving for y, we get

[tex]y = -5[/tex]

Therefore, the coordinates of the y-intercept is (0, -5).
