If x>0 and y=0, Where is the poiny (x,y) located?

​

Answer:

Step-by-step explanation:

x - y² = -1     ⇒   - y² = - x - 1    ⇒    y² = x + 1   {x≥-1}

4x² + 9y² = 72

4x² + 9(x + 1)² = 72

4x² + 9(x² + 2x + 1) = 72

4x² + 9x² + 18x + 9 - 72 = 0

13x² + 18x - 63 = 0     ⇒   a = 13,  b = 18,  c = -63

[tex]x=\dfrac{-18\pm\sqrt{18^2-4\cdot13\cdot(-63)}}{2\cdot13}=\dfrac{-18\pm\sqrt{324+252}}{26}=\dfrac{-18\pm\sqrt{576}}{26}\\\\x=\dfrac{-18+24}{26}=\dfrac3{13}\qquad\vee\qquad x=\dfrac{-18-24}{26}=-\dfrac{21}{13}\\\\ y^2= x + 1\quad\iff\quad x\ge-1\\\\y^2=\dfrac3{13}+1\\\\ y^2=\dfrac{16}{13}\\\\y=\dfrac{4}{\sqrt{13}}=\dfrac{4\sqrt{13}}{13}\qquad\vee\qquad y=-\dfrac{4\sqrt{13}}{13}[/tex]

When you use the pythagorean theorem u find 5m

Answer:

C

Step-by-step explanation:

The key here is she wants to make "at least", implying that you have an inequality.  If she cecks the house 4 times plus the 2 overnight stays then she will have exactly 150, so that is the least needed to reach her goal.  So at least automatically turns it into an inequality.

Answer:

the difference is -69

Step-by-step explanation:'

Since there is a negative sign in between the +12 becomes -12 . The you subtract the both.

Basically its adding 57 and 12 but then making it negative. So you would get -69.

Answer:

40

Can fit 4 length wise, 5 width wise, and 2 depth wise. So 40 packages total.

Answer:

C. 14 feet

Step-by-step explanation:

THIS IS TO FIGURE OUT THE TRIANGLE

You have to do the Pythagorean Theorem, which is a² + b² = c²

Since h is the entire piece of wood including the additional 2 feet, I will use m as variable for triangle

Fill in for variables: 5² + m² = 13²

Simplify: 25 + m² = 169

Subtract 25 from both sides: m² = 144

Square root both sides to get m alone: m = 12

Now, you have to add the additional 2 feet above the triangle: 12 + 2 = 14

Therefore, h=14

Answer:

12

Step-by-step explanation:

The only answer that makes sense. If you use pythagorean theorem which is a^2+b^2=c^2, and c is the hypotenuse, which is the slanting side, you do this

12^2+5^2=13^2?

144+25=169

169=169

it checks!

Answer:

p = 3.6

Step-by-step explanation:

Our goal is to isolate P.

Let's start by adding 4 to each side:

8p = 28.8

Next, we will divide each side by 8:

p = 3.6

I believe 72 years

Step-by-step explanation:

it has to be twenty characters so this to make it long enough

Answer:

12 years

Step-by-step explanation:

144,000.00 / 2,000.00 is 72 times that he deposited 2,000.00 in order to get 144,000.00.  If he deposits once every 2 months then he would have deposited 72 months x 2.  That is 144 months he took to deposit that much.  144 / 12 months in a year is 12 years.  He takes 12 years to save 144,000.00.

Answer:

hehe

Step-by-step explanation:

please

why

Step-by-step explanation:

diagonals of the rhombus bisect each other at right angles .

5a = 90

a = 90/5 = 18

in ∆ OCD:

5a + 2a + b = 180

7a+ b = 180

b = 180 - 7 ( 18)

b = 180 - 126

b = 54 °

plz mark my answer as brainlist plzzzz.

hope this will be helpful to you.☺️

Answer:

a = 18°

[tex] b= 108\degree [/tex]

Step-by-step explanation:

ABCD is a rhombus.

AC and BD are its diagonals

Diagonals of a rhombus bisects at right angles.

Therefore,

5a = 90°

a = 90°/5

a = 18°

2a = 2*18° = 36°

Diagonals of a rhombus bisects the opposite angles.

Therefore,

[tex] m\angle ADC = 2(2a)[/tex]

[tex] m\angle ADC = 2\times 36\degree [/tex]

[tex] m\angle ADC = 72\degree [/tex]

[tex] m\angle ADC+m\angle DCB= 180\degree [/tex]

(Adjacent angles of a rhombus are supplementary)

[tex] 72\degree+b= 180\degree [/tex]

[tex] b= 180\degree-72\degree [/tex]

[tex] b= 108\degree [/tex]

Answer:

Area of the sector = 78.54 square meters

Step-by-step explanation:

Radius of the given circle = 10 meters

Sector bounded by the arc having measure = 90°

Angle subtended by the arc at the center = 90°

Area of the sector = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]

Here angle θ is the angle at the center subtended by the arc.

If angle θ = 90°

Therefore, area of the sector = [tex]\frac{90}{360}(\pi)(10)^{2}[/tex]

                                                = 25π

                                                = 78.54 square meters

Answer:

a = 45°

Step-by-step explanation:

2a + a + a = 180°

4a = 180°

4a ÷ 4 = 180° ÷ 4

a = 45°

Answer:

Given :  A toy car is placed on the floor. Its movement details are given

To find : Distance covered by Car & graph to be plotted

Solution:

Start from rest

u = 0  at  t = 0

Constant acceleration for 3 sec reaching velocity 4 m/s

V = U +at

=> 4 = 0 +  a(3)

=>a = 4/3  m/s²

Distance here  S = ut + (1/2)at²

S = 0 + (1/2)(4/3)3²

=> S = 6 m

deceleration of 0.5 m/s² for 4 sec

=> v = 4  - (0.5)4

=> v = 2 m/s

Distance here   =  4(4)  - (1/2) (0.5)4²

= 16 - 4

= 12 m

Total Distance = 6 + 12 = 18 m

Total Distance traveled by toy Car = 18 m

Answer:

x=2/3+1/3[tex]\sqrt{10}[/tex]

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2−4x−2=0

For this equation: a=3, b=-4, c=-2

3x2+−4x+−2=0

Step 1: Use quadratic formula with a=3, b=-4, c=-2.

Answer:

Suppose that you have an initial quantity A.

If you have an increase of X%, the new quantity (NQ) is written as:

NQ = A + A*(X%/100%) = A*(1 + X%/100%).

Now, if we have an increase of 2% then:

NQ = A*(1 + 2%/100%) = A*(1 + 0.02)

And no we have another increase of 1%, then:

NQ = (A*(1 + 0.02))*(1 + 1%/100%) = A*(1 + 0.02)*(1 + 0.01) = A*1.0302

The single decimal multiplier that you can use to increase by 2% followed by a 1% increase is 1.0302
