Answer:
see explanation
Step-by-step explanation:
The vertex of f(x) = x² is at (0, 0)
To find the vertex of g(x) = x² - 8x + 7 ← in standard form
The x- coordinate of the vertex is
= -
where a = 1 and b = - 8
= - = 4
substitute x = 4 into the equation for corresponding y- coordinate
y = 4² - 8(4) + 7 = 16 - 32 + 7 = - 9
The vertex of g(x) is at (4, - 9)
thus (0, 0) → (4, - 9) is 4 units right and 9 units down → option C
2x2x2
2x2=4
4x2=8
2x2x2 is 8 because you have 3, 2s
The area is 32 but not sure
sin(2Θ) = 2cosΘsinΘ
sinΘ=opposite/hypotenuse=8/17
adjacent = (17^2 - 8^2)^1/2 =15
sin(2Θ) = 2cosΘsinΘ = 2 *(15/17)*(8/17)= 240/289
opposite of 2Θ equals 240
hypotenuse of 2Θ equals 289
adjacent of 2Θ = (289^2 - 240^2)^1/2 = 161
cos(2Θ) = 161/289
tan(2Θ) = 240/161
Answer:
105ft per minute
Step-by-step explanation:
well, if he/she walks 7ft in 4s, then you divide 60/4. In which you get 15.
15•7=105
