Answer:
y = -5x - 10
Step-by-step explanation:
-8-2 -10
____ = ___ = -5
3 - 1 2
Answer:
y = -5x + 7Step-by-step explanation:
Find the slope:
m = (- 8 - 2) / (3 - 1) = -10 / 2 = -5Use the point (1, 2) and find the equation:
y - 2 = -5(x - 1)y = -5x + 5 + 2y = -5x + 7The data given for a football kicked from the field follows a quadratic model, h(x) = - 3x2 + 18x + 7. Where h(t) is the height in feet and t is the in seconds. Using this model, what is the maximum height the ball will reach?
43 ft
7 ft
34 ft
17 ft
Answer:
C) 34
Step-by-step explanation:
use -b/2a to find the x value of the vertex (3)
then plug 3 into equation
- 3(3)² + 18(3) + 7
the answer is 34

3 dogs plus 5 cats cost $365. 5 dogs plus 3 cats cost $491. What is the cost of one cat?
Answer:
Solution given;
let dogs be d and cats be c.
according to the question
3 d +5 c =$365........[1]
5d+3c=$491.............[2]
By doing elimination method
multiplying equation 1 by 5 and equation 2 by 3 and subtracting
we get
15d+25c=$365*5
15d+9c=$491*3
- - -
____________
;16c=$352
c=[tex] \frac{352}{16} [/tex]=$22
the cost of one cat is $22.
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles
Complete question :
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is NOT yellow.
Answer:
Step-by-step explanation:
Total number of marbles :
Blue = 1 ; yellow = 6 ; red = 7 ; green = 4 ; purple = 6
Total = (1 + 6 + 7 + 4 + 6) = 24 marbles
Probability of selecting marble that is not yellow :
Number of marbles that aren't yellow / total number of marbles
Marbles that aren't yellow = 24 - 6 = 18
P(selecting a marble that isn't yellow) = 18 / 24 = 3/4
use the picture to write each ratio as a simplified fraction (how are you going to find the length of the third side?) show your thinking
Answer:
See belowStep-by-step explanation:
to figure out the ratios we must figure out the length of hypotenuse first to do so we can consider Pythagoras theorem given by
[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] \displaystyle \implies c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
substitute:
[tex] \displaystyle c = \sqrt{ {12}^{2} + {9}^{2} } [/tex]
simplify squares:
[tex] \displaystyle c = \sqrt{ 225 } [/tex]
simplify square root:
[tex] \displaystyle c = 15[/tex]
now recall that,
[tex] \displaystyle \sin( \theta) = \frac{opp}{hypo} [/tex][tex] \displaystyle\cos( \theta) = \frac{adj}{hypo} [/tex][tex] \displaystyle \tan( \theta) = \frac{opp}{adj} [/tex]the ratios with respect to angle w given by
[tex] \displaystyle \sin( W) = \frac{12}{15} = \frac{4}{5} [/tex][tex] \displaystyle \cos(W) = \frac{9}{15} = \frac{3}{5} [/tex][tex] \displaystyle \tan( W) = \frac{12}{9} = \frac{4}{3} [/tex]the following ratio with respect to angle X
[tex] \displaystyle \sin(X) = \frac{9}{15} = \frac{3}{5} [/tex][tex] \displaystyle \cos(X) = \frac{12}{15} = \frac{4}{5} [/tex][tex] \displaystyle \tan( X) = \frac{9}{12} = \frac{3}{4} [/tex]Which measurement can be used to describe the size of an angle

HELP IM GOING TO HAVE A MENTAL BREAKDOWN
Find the values of x and y that make these triangles congruent by the HL Theorem.
Answer:
x = 3 ; y=2
Step-by-step explanation:
to simplify the work we can build a system of two equations
2x+3 = 3y+3
x = y+1
we can now substitute the value of x in the first equation
2(y+1)+3 = 3y+3
2y + 2 + 3 = 3y+3
2y + 5 = 3y+3
y = 2
now we can subisitute the value of y in the first equation
x = 2 + 1 = 3
Verify
2(3)+3 = 6+3 = 9
3(2) + 3 = 6 + 3 = 9
3
2+1 = 3

Answer:
The probability that Tara will select a blue marble from each bag is [tex]\frac{2}{27}[/tex].
Step-by-step explanation:
Since there are 15 marbles in the first bag and 9 marbles in the second bag, that means there are a total of 135 different combinations of one marble from each bag. Since there are 5 blue marbles in the first bag and 2 blue marbles in the second bag, there are 10 different possible combinations of one blue marble from each bag. The probability that Tara will select a blue marble from each bag can be represented as [tex]\frac{10}{135}[/tex] or [tex]\frac{2}{27}[/tex].

Answer:
I would say not here D.
Step-by-step explanation:
Because I found the area of the base first *the square* which is 4 x 11 = 44 and the rectangles are 4 x 14= 56 x 2 since there are 2 rectangles is 112. Then the triangles are 11x14=154/2=77 x 2 since there are 2 triangles is 154. Then we add up all those numbers 44+112+154= 310 not 308 *C*.

Answer:
1: 233 m
2: 466 m
3: 241.87 m
4: 483.72
Step-by-step explanation:
The Pythagorean Theorem states that a^2 + b^2 = c^2, in which c is the hypotenuse (in this case, PQ and RS).
1: 105^2 + 208^2 = 54289, square root of 54289 = 233
2: Since the area of the triangle makes up half of the rectangle, multiply the area by 2 to get 466
3: 120^2 + 210^2 = 58500, square root of 58500 is 241.87
4: Multiply by 2 to get 483.72

What is the measure of X , in degrees?
Answer:
71°
Step-by-step explanation:
The angle of x and angle of 109, are supplementary, which means when added they are equal to 180 degrees.
109 + x = 180
x = 180 - 109
x = 71
Answer:
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40

Step-by-step explanation:
Andy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber needed was 62 feet. What was the percent error of Andy's estimation?
Answer:
17.74%
Step-by-step explanation:
The formula for percent error is given as:
|Estimated value - Actual value|/Actual value × 100
From the above question:
Estimated value = 73 feet
Actual value = 62 feet
Hence,
Percent error = |73 - 62|/62 × 100
= 11/62 × 100
= 17.741935484%
Approximately , percent error = 17.74%
Therefore, the percent error of Andy's estimation is 17.74%
