Given four functions, which one will have the highest y-intercept?
FinnZ [79.3K]
Here are the four functions :
<span>1) Blake is tracking his savings account with an interest rate of 5% and a original deposit of $6.
</span>Equation : y = 0.05x + 6
y-intercept = (0,6)

2) <span>x           g(x)
    1            6
    2            8
    3           12
 y-intercept = (0,5)

3) T</span><span>he function h of x equals 4 to the x power, plus 3
    equation : y = 4^x + 3
y-intercept = (0,4)

4) </span><span>j(x) = 10(2)x
y-intercept = (0,1)

Best choice : f(x) has the highest y-intercept.</span>

4. Find the lateral area and surface area of the given prism.
scoundrel [369]

Answer:

<h2>Q4. S.A. = 752.28 m²</h2><h2>Q11. V = 384 ft³</h2>

Step-by-step explanation:

\bold{Q4}\\\text{We have}\\\text{two right triangles with legs a = 4m and b = 7m}\\\text{three rectangles}\ 7m\ \times 38m,\ 8.06m\ \times\ 38m\ \text{and}\ 4m\ \times\ 38m\\\\\text{The formula of an area of a right triangle:}\\\\A=\dfrac{ab}{2}\\\\\text{substitute:}\\\\A_1=\dfrac{(4)(7)}{2}=\dfrac{28}{2}=14\ m^2\\\\\text{The formula of an area of a rectangle}\ l\ \times w:\\\\A=lw\\\\\text{substitute:}\\\\A_2=(7)(38)=266\ m^2\\A_3=(8.06)(38)=306.28\ m^2\\A_4=(4)(38)=152\ m^2\\\\\text{The Surface Area:}

S.A.=2A_1+A_2+A_3+A_4\\\\S.A.=2(14)+266+306.28+152=752.28\ m^2

\bold{Q11}\\(look\ at\ the\ picture)\\\\\text{The formula of a volume of a pyramid:}\\\\V=\dfrac{1}{3}BH\\\\B-\text{area of a base}\\H-\text{height}\\\\\text{In the base we have the square. The formula of an area of a square with side a:}\\\\A=a^2\\\\\text{We have}\ a=12ft.\ \text{Substitute:}\\\\B=12^2=144\ ft^2\\\\\text{For}\ H\ \text{we need use the Pythagorean theorem:}\\\\H^2+6^2=10^2\\\\H^2+36=100\qquad\text{subtract 36 from both sides}\\\\H^2=64\to H=\sqrt{64}\\\\H=8\ m

\text{Substitute:}\\\\V=\dfrac{1}{3}(144)(8)=(48)(8)=384\ ft^3
