Find the value of (2.8-0.45)²+∛5.832

Mathematics
1 answer:
Ilya [14]4 years ago
8 0
As you can see, 2.8 - 0.45 is 2.35.


Now, 2.35 squared is 5.225

∛5.832 if you simplify this you get 1.8.

1.8 + 5.225 = 7.3225

Hope this helps :)

Answer:

x = 8.3 is the value of x.

Step-by-step explanation:

Given:

Let Δ ABC be a Right angle Triangle at ∠ C = 90°

AB = x

BC = 6

m∠ B = 44°

To Find:

x = ?

Solution:

We apply Cosine Rule

{tex}\cos B = \frac{\textrm{side Adjacent to angle B}}{Hypotenuse}  \\{/tex]

Substituting the given values we get

\cos B = \frac{BC}{AB}\\\\\cos 44 = \frac{6}{x}\\\\0.719=\frac{6}{x}\\\\\therefore x=\frac{6}{0.719} \\\\\therefore x=8.3......(nearest\ tenth)

The value of x is

x = 8.3

I would like to know what 1.34 as a fraction in simplest form would be
Paha777 [63]
1.34 = 1 \dfrac{34}{100} = 1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}





-------- Edited to include more explanation --------------

1.34 = 1 whole 34 hundredth 

\text { 1 whole 34 hundredth written as a fraction =} 1 \dfrac{34}{100}

Then we simplified it by dividing the numerator and the denominator by 2:

1 \dfrac{34}{100}  = 1 \dfrac{34 \div 2}{100 \div 2}

34 divided by 2 will give us 17 and 100 divided by 2 will give us 50:

1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}

About what point on parabola y=x^2 is 5 units away from the origin along the curve
konstantin123 [22]

the distance from the origin is 5, so

sqrt(x²+y²)=5

x²+y²=25

substitue y=x²

y+y²=25

y²+y-25=0

solve using calculator or the formula

to get

y =( -1+sqrt(1+4*25))/2

or y = (-1-sqrt(1+4*25))/2

the second solution is rejected because a square cannot be negative

the value of x is the positive or negative (sqrt... or -sqrt...) or y

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A construction
charle [14.2K]

Answer:

y=\frac{11}{20}x+6

Step-by-step explanation:

Given:

Two points are given

x = number of minutes

y = length of the lin

(x_{1},y_{1} ) ⇒ (0, 6)

(x_{2},y_{2} ) ⇒ (20, 17)

We need to find the equation that represents the relationship between x, y.

Solution:

Using slope formula to find the slope of the equation of the line.

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substitute (x_{1},y_{1} ) = (0, 6) and (x_{2},y_{2} ) = (20, 17) in above equation.

m=\frac{17-6}{20-0}\\m=\frac{11}{20}

So, slope of the line m = \frac{11}{20}

Using point slope formula.

(y-y_{1})=m(x-x_{1}) ------------(1)

Where, m = slope of the line

Substitute (x_{1},y_{1} ) ⇒ (0, 6) and m = \frac{11}{20} in equation 1.

(y-6)=\frac{11}{20} (x-0)

y-6=\frac{11}{20}x

Add 6 both side of the equation.

y-6+6=\frac{11}{20}x+6

y=\frac{11}{20}x+6

Therefore, the equation that represents the relationship between x and y is written as:

y=\frac{11}{20}x+6
