Step-by-step explanation:

[tex]y + (z - 7) {}^{2} \times 2 \\ 3 + (9 - 7) {}^{2} \times 2 \\ 3 + (2) {}^{2} \times 2 \\ 3 + 4 \times 2 \\ 3 + 8 = 11[/tex]

Step-by-step explanation:

EXAMPLE OF SURFACE AREA

Answer:

6×pi ft

Step-by-step explanation:

the area of a circle is

pi × r²

with r being the radius of the circle.

so,

9×pi = r² × pi

9 = r²

r = 3 ft

the circumference of a circle is

2×pi× r

that means in our case it is

2×pi×3 = 6×pi ft

Answer:

(4, 0)

Step-by-step explanation:

Answer:

x = 39

Step-by-step explanation:

all triangles have angle measures that add up to 180°.

This means that to find what x is, you add 102 and 39, and then subtract that from 180, so

180-(102+39) = x

180-141=x

39=x

Answer:

x° = 39°

Step-by-step explanation:

According to the angle sum property of triangles, the 3 angles in a triangle will sum up to 180°.

102° + 39° + x° = 180°

141° + x° = 180°

x° = 180° - 141°

x° = 39°

Answer:

what is intercept: intercept simply means a point on the y axis through which a slope passes and also in the equation you were given y = mx + c I mean y = 2x -2 the c is the intercept meaning -2 .

so wherever that straight line meets with with y axis the number at that very point is your intercept.

the y intercept for the first one is -2

and it's "less than" since it's a negative number.

Because in this case it is less than and the -3x would be cancelled out and I had this question and that correct answer was A(1,-5).

Hope this helps:)

Answer:

the answer is (1,-5)

Step-by-step explanation:

plug in the x and y values and see if they are true

y<-3x+3

(-5)<-3(1)+3

-5<-3+3

-5<0 is true

y<x+2

(-5)<(1)+2

-5<1+2

-5< 3 is true also

The equation is  4^{3x} is equal to 8^{1/x} 2^{x+3} and the values of x are x is equal to (3+√69)/(10) or x is equal to (3-√69)/(10)

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]

where 'a' is a constant and a>1

After following the rules to model the equation.

The equation becomes:

[tex]\rm 4^3^x= 8^{1/x}\times 2^{x+3}[/tex]

After solving, we get:

[tex]2^{6x}= 2^{3/x \ +x+3}[/tex]  (power rule)

Taking log on both sides with base 2

[tex]\rm log_2(2^{6x})= log_2(2^{3/x \ +x+3})[/tex]

After solving, we will get a quadratic equation:

[tex]\rm 5x^2-3x-3 = 0[/tex]

After using quadratic formula, we will get,

[tex]\rm x=\dfrac{3+\sqrt{69}}{10}[/tex] or

[tex]\rm x=\dfrac{3-\sqrt{69}}{10}[/tex]

Thus, the equation is  4^{3x} is equal to 8^{1/x} 2^{x+3} and the values of x are x is equal to (3+√69)/(10) or x is equal to (3-√69)/(10)

The total number of grams of the supplement in one capsule will be 0.45 grams.

The measurement of any quanity is expressed by its unit. Now the units for the same matter can be expressed in different ways for higher quanity or lower quanity so we need to convert the units for the calculations.

Here in the question

Each capsule has 450 miligrams of supplement.

Total grams in one capsule will be calculated by unit conversion

[tex]\rm 1 \ gram=1000\ miligram\\\\\\1 \ Mg=\dfrac{1}{1000}\ gram\\\\\\450\ Mg=\dfrac{450}{1000}\ gram\\\\\\450 Mg=0.45\ gram[/tex]

Hence the total number of grams of the supplement in one capsule will be 0.45 grams.

The division is one of the four fundamental arithmetic operations. The rent of the flat for each month will be Rs. 30,000.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that the rent of the flat for one year is Rs. 3,60,000. Since a year has 12 months. Therefore, the rent for each month will be,

[tex]\rm \text{Rent for one month} = \dfrac{Rs.\ 3,60,000}{12} = Rs.\ 30,000[/tex]

Hence, the rent of the flat for each month will be Rs. 30,000.

The equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3

The identity is used to find the measure of sides and acute angles of a right triangle

From the diagram shown, <ABC is the reference abgle hence;

Opposite side = 2,4cm

Hypotenuse .=10.3cm

According to the identity

sin x = opp/hyp

sinx = 2.4/10.3
sinx = 0.233

x =  13.47 degrees
