Answer:

For this case we can model the problem as a rectangle triangle.

 We know:

 Length of the hypotenuse

 Angle between the base of the triangle and the hypotenuse.

 We want to know:

 Length of the base.

 For this we use the following trigonometric relationship:

 cos (15) = \frac{x}{500}cos(15)=500x

 Clearing x we have:

 x = 500 * cos (15) x = 482.96x=500∗cos(15)x=482.96

 Rounding to the nearest tenth of a meter:

 x = 483.0 mx=483.0m

 Answer:

 The horizontal distance she has covered is:

 x = 483.0 mx=483.0m

Answer:

The tree is 28 feet in height.

Step-by-step explanation:

This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.

74 / x = 102/39           Cross Multiply

102x = 74*39              The inches as a unit cancel out.

102x = 2886               Divide by 102

x = 2886/102

x = 28.29 feet

Answer:

C

Step-by-step explanation:

Each input value can have only one output value for it to be a function. In other words, there should only be one y value for each x value. The only option that satisfies this is C.

Answer:

see below

Step-by-step explanation:

1. x-9=-17-simplifies to a single solution-one solution

2.x+4=4+x-same thing on each side-infinite solutions

3. 0.4x=0.4x+2-same variable coefficient plus a number-no solutions

4. 5x=5x-3-same as above-no solutions

5. 5x=2-variable on one side, constant on another-one solution

6. x-5=x-5-same thing on each side-infinite solutions

7.3x=3x-same thing as above-infinite solutions

8.8x-10=8x-same coefficient for each variable plus a constant-no solutions

Answer:

One solution:

x + 9 = -17

5x = 10

No solution:

0.4x = 0.4x +2

5x = 5x - 3

8x - 10 = 8x

Infinite solutions:

x + 4 = 4 + x

x - 5 = x - 5

3x = 3x

Step-by-step explanation:

x + 9 = -17

  - 9     -9

x = -26 (one solution)

x + 4 = 4 + x

  - 4   - 4

x = x (infinite solutions)

0.4x = 0.4x +2

-0.4x  -0.4x

0 = 2 (no solution)

5x = 5x - 3

-5x  -5x

0 = -3 (no solution)

5x = 10

/5   /5

x = 5 (one solution)

x - 5 = x - 5

 + 5       + 5

x = x (infinite solutions)

3x = 3x (infinite solutions)

8x - 10 = 8x

    + 10  + 10

8x = 8x + 10

-8x   -8x

0 = 10 (no solution)

We are given with an equation and need to find it's solution set also we are given with a condition that m ≠ {0, 1} . So , let's start ;

So we are given with :

[tex]{:\implies \quad \sf \dfrac{6}{m}+2=\dfrac{m+3}{m-1}}[/tex]

First , we will simplify the given Equation and then we will solve it . So , now taking LCM in LHS ;

[tex]{:\implies \quad \sf \dfrac{6+2m}{m}=\dfrac{m+3}{m-1}}[/tex]

Now , Cross Multiplying ;

[tex]{:\implies \quad \sf (m-1)(6+2m)=m(m+3)}[/tex]

[tex]{:\implies \quad \sf m(6+2m)-1(6+2m)=m^{2}+3m}[/tex]

[tex]{:\implies \quad \sf 6m+2m^{2}-6-2m=m^{2}+3m}[/tex]

Now , transposing whole RHS to LHS and collecting like terms ;

[tex]{:\implies \quad \sf (2m^{2}-m^{2})+(6m-2m-3m)-6=0}[/tex]

[tex]{:\implies \quad \sf m^{2}+m-6=0}[/tex]

Now , we will solve this by splitting the Middle term ;

[tex]{:\implies \quad \sf m^{2}+3m-2m-6=0}[/tex]

[tex]{:\implies \quad \sf m(m+3)-2(m+3)=0}[/tex]

[tex]{:\implies \quad \sf (m+3)(m-2)=0}[/tex]

So , now either , m+3 = 0 or m-2 = 0 . On simplification we will get , m = 2 , -3. So m = {-3, 2}

Hence Option 1) {-3, 2} is correct

Answer:

c > 1

Step-by-step explanation:

Given equation: [tex]x^2-2x+c=0[/tex]

General form of quadratic equation: [tex]ax^2+bx+c=0[/tex]

We can use the discriminant to determine the value of c for which the equation has no real roots.

[tex]b^2-4ac < 0\implies \textsf{no real roots}[/tex]

From the given equation:

Inputting these values into the discriminant formula:

[tex]\implies (-2)^2-4(1)(c) < 0[/tex]

[tex]\implies 4-4c < 0[/tex]

[tex]\implies 4 < 4c[/tex]

[tex]\implies 1 < c[/tex]

[tex]\implies c > 1[/tex]

Here

Discriminant must be less than 0

[tex]\\ \rm\Rrightarrow b^2-4ac<0[/tex]

[tex]\\ \rm\Rrightarrow (-2)^2-4(1)(c<0[/tex]

[tex]\\ \rm\Rrightarrow 4-4c<0[/tex]

[tex]\\ \rm\Rrightarrow 4(1-c)<0[/tex]

[tex]\\ \rm\Rrightarrow 1-c<0[/tex]

[tex]\\ \rm\Rrightarrow 1<c[/tex]

[tex]\\ \rm\Rrightarrow c>1[/tex]

The bat will fit in the box if the length of the bat is less than the interior diagonal of the box

Julian's bat will not fit inside the box

From the complete question, the dimension of the box is:

32 in by 6 in by 8 in

Start by calculating the diagonal (d) of the base of the box using the following Pythagoras theorem

[tex]d^2 = 6^2 + 8^2[/tex]

Next, calculate the length of the interior diagonal of the box.

[tex]L = \sqrt{32^2 + d^2\\[/tex]

This gives

[tex]L = \sqrt{32^2 + 6^2 + 8^2}[/tex]

Evaluate

[tex]L = 33.53[/tex]

The length of the bat (34 inches) is greater than the interior diagonal of the box (33.53 inches)

Hence, the bat will not fit inside the box

Answer: 8/7

Step-by-step explanation:

Step-by-step explanation:

Hopefully this helps you,
So if A= 70 degrees, C will also 70 degrees.
The parallelogram will always equal 360 degrees, so 70(2) = 140.
Then 360 - 140 = 220.
Then divide 220 by 2, so 220/2 = 110.
Therefore angles B and D are 110 degrees.
So your answer,
C = 70 degrees
B and D = 110 degrees

A horizontal line has slope = 0.

Answer:

1.[tex]y=2x+4[/tex]
2.[tex]y=1x+3[/tex]

Step-by-step explanation:

Given the following questions:

Question one:

Point A = (-1, 2) = (x1, y2)
m = 2

To find the answer we will use the formula to find the slope intercept, substitute the values and then solve for b.

[tex]y=mx+b[/tex]
[tex]m=2[/tex]
[tex]x=-1[/tex]
[tex]y=2[/tex]
[tex]2=2(-1)+b[/tex]
[tex]2\times-1=-2[/tex]
[tex]2=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]2+2=4[/tex]
[tex]4=b[/tex]
[tex]b=4[/tex]
[tex]y=2x+4[/tex]

The slope intercept form of the line that passes through (-1, 2) and has a slope of 2 is "y = 2x + 4."

Question two:

Point A = (-1, 2) = (x1, y1)
Point B = (2, 5) = (x2, y2)

To find the slope intercept form we must first find the slope using the formula to calculate slope or rise over run.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{5-2}{2--1}=\frac{3}{3}[/tex]
[tex]3\div3=1[/tex]
[tex]m=1[/tex]

Now that we have the slope, we will use the formula for slope intercept, substitute the values, then solve for b.

[tex]y=mx+b[/tex]
[tex]m=1[/tex]
[tex]y=2[/tex]
[tex]x=-1[/tex]
[tex]2=1(-1)+b[/tex]
[tex]1\times-1=-1[/tex]
[tex]2=-1+b[/tex]
[tex]-1+1=0[/tex]
[tex]2+1=3[/tex]
[tex]3=b[/tex]
[tex]b=1[/tex]
[tex]y=1x+3[/tex]

The line that passes through the points (4, -2) and (2, 5) in slope intercept form is indeed "y = 1x + 3."

Hope this helps.
