Given ABC is an isosceles triangle with AB = BC. If the measure of
A)43°

B)86°

C)94°

D)137°

-18x

you first times the numbers, which becomes -18

Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)

Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)

-18x

Answer: Select the first one

Step-by-step explanation:

-6 multiplied 3 is -18

AND they both have power x which means  -6x⁸   multiply 3x ⁻⁷

                                                         =  -18 x⁸ ⁺⁽⁻⁷ ⁾(As the have same variable )

                                                         =  -18 x⁸⁻⁷

                                                           =-18 x

Answer:

x = 119°

Step-by-step explanation:

The angle between chord KJ and chord LM is half the sum of the arcs intercepted by the angle and its vertical angle, that is

[tex]\frac{1}{2}[/tex] (75 + 47)° = 0.5 × 122° = 61°

This angle and x are adjacent angles and sum to 180° , then

x = 180° - 61° = 119°

Answer:

1.37 x 10^-9 F

Step-by-step explanation:

(8.85 x 10^-12) * (0.155) = 1.37 E -12

1.37 E -12 / 0.00100 = 1.37 x 10^-9

Answer:

Step-by-step explanation:

70+85+150+x=360 degree(sum of 4 angles is always 360 degree)

305+x=360

x=360-305

x=55 degree

Answer:

85+1 50+70+x=360{ sum of interior angels of of quadrilateral}

305+x=360

x=360-305

x=55degree

Answer:

x = -2/15.

Step-by-step explanation:

Finding the second derivative:

f'(x) = 15x^2 +4x - 3

f"(x) = 30x + 4

30x + 4 = 0   for a point of inflection

x = -4/30 =  -2/15

So 30x + 4 is negative up to x =  -2/15 and positive thereafter.

So the curve passes from concave downward to concave upward at x = -2/15.

Answer:

[tex] \displaystyle \left( - \frac{2}{15} , \frac{286}{675} \right)[/tex]

Step-by-step explanation:

to figure out the infection point

take derivative both sides:

[tex] \displaystyle f'(x) = \frac{d}{dx} {5x}^{3} + 2 {x}^{2} - 3x[/tex]

By sum derivation rule we acquire:

[tex] \displaystyle \rm f'(x) = \frac{d}{dx} {5x}^{3} + \frac{d}{dx} 2 {x}^{2} - \frac{d}{dx} 3x[/tex]

apply exponent derivation rule which yields:

[tex] \displaystyle f'(x) = {15x}^{2} + 4{x}^{} - 3[/tex]

take derivative in both sides once again which yields:

[tex] \rm\displaystyle f''(x) = \frac{d}{dx} {15x}^{2} + \frac{d}{dx} 4{x}^{} - \frac{d}{dx} 3[/tex]

remember that, derivative of a constant is always 0 so,

[tex] \rm\displaystyle f''(x) = \frac{d}{dx} {15x}^{2} + \frac{d}{dx} 4{x}^{} - 0[/tex]

by exponent derivation rule we acquire:

[tex] \rm\displaystyle f''(x) = {30x} + 4{}^{} [/tex]

substitute f''(x) to 0 figure out the x coordinate of the inflection point:

[tex] \rm\displaystyle {30x} + 4{}^{} = 0[/tex]

cancel 4 from both sides:

[tex] \rm\displaystyle {30x} = - 4[/tex]

divide both sides by 30:

[tex] \rm\displaystyle {x} = - \frac{2}{15} [/tex]

now plugin the value of x to the given function to figure out the y coordinate of the inflection point:

[tex] \rm \displaystyle f(x) = {5 \left( - \frac{2}{15} \right) }^{3} + 2 {\left( - \frac{2}{15} \right) }^{2} - 3 \left( - \frac{2}{15} \right)[/tex]

By simplifying we acquire:

[tex] \displaystyle f(x) = \frac{286}{675} [/tex]

hence,

the coordinates of inflection point are

[tex] \displaystyle \left( - \frac{2}{15} , \frac{286}{675} \right)[/tex]

Answer:

45°

Step-by-step explanation:

Let :-

We know :-

On adding :-

→ x + 3x = 180°

→ 4x = 180°

→ x = 180°/4

→ x = 45°

I think its c but just so you know I'm not really smart so I might be wrong

Answer:

Step-by-step explanation:

x+y = 6

y = (6-x)

7x +12y = 52

7x+12(6-x) = 52

7x +72 -12x = 52

-5x = -20

x= 4     4 days at $7  = $28

           2 days at $12 = $24

 28+24 = 52

Answer:

The right solution is "$1,920,000".

Step-by-step explanation:

Given:

Project cost,

= $1200000

Dr. Leonard sells by

= 60%,

The mark up value will be:

= [tex]\frac{1200000\times 60}{100}[/tex]

= [tex]720,000[/tex] ($)

hence,

The selling price he should put with the bank will be:

= [tex]Project \ cost+Mark \ up \ value[/tex]

= [tex]1200000+720000[/tex]

= [tex]1,920,000[/tex] ($)
