from the equal angles it is an isosceles triangle, AB = AC.

4x + 1 = 2x + 23

4x - 2x = 23 - 1

2x = 22

x = 22 : 2

x = 11

----------------------

4 * 11 + 1 = 2 * 11 + 23

45 = 45

--------------

now we find BC

3x - 8

3 * 11 - 8 =

25 (is the value of BC)

Simplifique a expressão 10ny-10x+10ny+10y

IRISSAK [1]

Responder:

10 (2ny- (x-y))

Explicación paso a paso:

Dada la expresión 10ny-10x + 10ny + 10y, para simplificar la expresión, se deben seguir los siguientes pasos;

Paso 1; Separa la expresión en términos similares

= 10ny-10x + 10ny + 10y

= (10ny + 10ny) - (10x + 10y)

Paso 2: Factoriza los valores comunes en ambos paréntesis

10ny (1 + 1) - 10 (x-y)

= 10ny (2) - 10 (x-y)

= 20ny - 10 (x-y)

Factoriza nuestro valor común en ambos términos:

= 10 (2ny- (x-y))

Consider firing a pumpkin from a canon at a target that is 17 meters away. The pumpkin follows a quadratic path as displayed to

bixtya [17]

A.
(0,00
(2.6,7.9)
(4.8,12.4)
(9.7,15.1)

b.
well, the points don't look like they are on the line but they actually are (plot twist)

so
since (0,0) is on th egarph

0=a(0)²+b(0)+c
0=c
so
f(x)=ax²+bx+0 or
f(x)=ax²+bx

find a and b
sub points

(2.6,7.9)
7.9=a(2.6)²+b(2.6)
7.9=6.76a+2.6b

(4.8,12.4)
12.4=a(4.8)²+b(4.8)
12.4=23.04a+4.8b

use those 2 equations
7.9=6.76a+2.6b
12.4=23.04a+4.8b

eliminate b
multiply first equation by -4.8 and 2nd by 2.6 and add them
-37.92=-32.448a-12.48b
32.24=59.904a-12.48b +
-5.68=27.456a+0b

-5.68=27.456a
divide both sides by 27.456
(-5.68/27.456)=a
find b

12.4=23.04a+4.8b
12.4=(-130.8672/27.456)+4.8b
12.4+(130.8672/27.456)=4.8b
(12.4+(130.8672/27.456))/4.8=b

da equation is
$y= \frac{-5.68}{27.456} x^2+ \frac{12.4+\frac{130.8672}{27.456}}{4.8}x$

c. the roots are found with your calculator
the roots are at x=0 and x=17.287323943662
so very close to the target but not exactly on it
if the target has a radius of 0.287323943662 or more then it will hit the target

A company borrows $100,000 by signing a $100,000, 5% note that requires four equal payments of

Kipish [7]

Answer:

The annual repayment is what the question required,which is $ 28,200.79

Step-by-step explanation:

The amount the company at year end would include the original amount of principal which is $25,000 ($100,000/4 years ), as well as the interest payable at 5% cost of borrowing.

The actual repayment requires at each year end is the original loan of $100,000 divided by the present value of four annual payments discounted at 5% which is 3.5460

Annual repayment=$100,000/3.5460=$28,200.79

Interest yearly=$28,200.79-$25,000.00=$3,200.79
