Step-by-step explanation:
Given
Equation of line is [tex]y=2x[/tex]
Equation of line with slope m and intercept c on Y-axis is
[tex]y=mx+c[/tex]
Comparing the given line with slope-intercept form
[tex]\Rightarrow m=2\ \text{and}\ c=0[/tex]
The slope is also equal to [tex]\tan \theta[/tex]
[tex]\Rightarrow \tan \theta =2\\\Rightarrow \theta =63.43^{\circ}[/tex]

Make a line that passes through the origin at an angle of [tex]63.43^{\circ}[/tex] with the x-axis.*ANSWER ASAP!! ITS FOR MY EXAM*
Matt drives 750 miles each month. He averages 21.5 MPG. If gas costs $3.15 per gallon, how much does he pay per month in gas?
a.) $75.15
b.) $100.88
c.) $109.88
Answers
Answer: c) $109.88
Step-by-step explanation: divide 750 by 21.5 to figure out how many gallons he would need and than multiply that by $3.15 to find out how much it would cost and you get $109.88
Answer:
109.88
Step-by-step explanation:
Divide 750 by 21.5. Then multiply the result by 3.15.
A tree is broken at a height of 7m from the ground and its top touches the ground at distance of 24m from the base of the tree. Find the original height of the tree. pls help with steps
Answers
then total height of tree=7+x
since it form a right angled triangle with base 24m and height 7m and hypotenuse be x
then by using Pythagoras theorem
(hypotenuse)^2=(base)^2+(height)^2
x^2=24^2+7^2
x^2=576+49
x^2=625
x=25
therefore height of tree =x+7=25+7=31
For which values of x will the rational expression below be undefined? Check
all that apply.
(x - 1)(x + 1)
X + 2
A. -1
B. 1
C. -2
D. 2
E. -5
F 5
Answers
Answer:
-2
Step-by-step explanation:
For the given expression to be undefined, this means that the denominator must be zero.
From the given expression, the denominator is x + 2
Equating this to zero;
x+2 = 0
Subtract 2 from both sides
x+2-2 = 0 -2
x = -2
Hence the value of x that makes it undefined is -2

Answer:
88
Step-by-step explanation:
X° + 116° = 180°(sum of opposite angle of a quadrilateral in circle is equal 180 °)
x°=180-116
x°=64°
therefore
A=(2(64)-40)
A=88°

Answer:
x = 3
Step-by-step explanation:
The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:
x(x -2)(x +3) -18 = 0
The attached shows x = 3 is the only real solution.
_____
We're not sure what "system of equations" is intended. Perhaps it is ...
y = 18
y = x(x -2)(x +3)
To create the expression we graphed, we effectively subtracted the first equation from the second.

Olivia buys cookies and apples at the store.
• She pays a total of $24.79.
• She pays a total of $4.75 for the cookies.
• She buys 4 bags of apples that each cost the same amount.
Answers
Because $24.79-4.75= $20.04
You said she bought 4 bags of apples each costing the same so now you divide $20.04 by 4 giving you $5.01

Complete Question:
State whether each set of hypothesis is valid for a statistical test and briefly explain why ?
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]
Answer:
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex] --- Valid
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex] --- Invalid
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex] --- Invalid
Step-by-step explanation:
For a test of hypothesis to be valid, the null hypothesis has to contain some form of equality i.e. [tex]=, \le,\ or\ \ge[/tex]
So, the above will be used to test for validity in the given tests of hypotheses.
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]
This is valid because the null hypothesis has an equality sign.
The null hypothesis is: [tex]H_0:\mu = 10[/tex]
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]
This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p \ne 0.5[/tex]
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]
This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p_1 <p_2[/tex]
