Answer:

Step-by-step explanRemember: logax=b⇒ab=x

in which "a" is the base of the log.

log4 (1/16) = 4^-2 = 1/4^2 = 1/16

4 to the power of -2 is equal to 1/16.

To answer this question, the equation in exponential form of "log4 (1/16) = -2" is " 4^-2 " (4 to the power of -2). :D

-3+1+10x= x+4<br> Solve the equation

tatuchka [14]

Answer:

x = 2/3 or 0.666...

Step-by-step explanation:

-3 + 1 + 10x = x + 4

-2 + 10x = x + 4

10x = x + 4 + 2

10x = x + 6

10x - x = 6

9x = 6

x = 6/9

x = 2/3 or 0.666...

(a) Name the minor arc __________ Name the major arc ___________

iragen [17]

Answer:

Part a) minor arc: XY; major arc: XVY

Part b) $248\°$

Part c) The tangent line is UV and the secant line is XY

Part d) $UV=6\sqrt{5}\ units$ or $UV=13.42\ units$

Step-by-step explanation:

Part a) we know that

The major arc is the larger arc joining two points on the circumference of a circle. Is an arc larger than a semicircle.

The sum of major and minor arcs is the whole circle, 360°

In this problem, possible major arcs are

VYX, VXY, XVY

and the corresponding minor arcs are

VX, VY, XY

Part b) we know that

The sum of major and minor arcs is the whole circle, 360°

Let

x------> measure minor arc

y-------> measure of major arc

$x+y=360\°$

we have

$x=112\°$

substitute

$112\°+y=360\°$

$y=360\°-112\°=248\°$

Part c) we know that

A tangent line intersects a circle at exactly one point.

In this problem

The tangent line is UV

A secant line intersects a circle in two points.

In this problem

The secant line is XY

Part d) we know that

The <u>Intersecting Secant Theorem</u> States: When two secant lines intersect each other outside a circle, the products of their segments are equal

$UV*UV = UX*UY$

$UV^{2} = 9*(9+11)$

$UV^{2} = 180$

$UV=\sqrt{180}\ units$

Simplify

$UV=6\sqrt{5}\ units$ or $UV=13.42\ units$

Researchers have noted a decline in cognitive functioning as people age (Bartus, 1990). However, the results from other research

kolbaska11 [484]

Complete Question

The complete question is shown on the first uploaded image

Answer:

Yes the researcher can conclude that the supplement has a significant effect on cognitive skill

$d = 0.5778$

The result of this hypothesis test shows that there is sufficient evidence to that the supplement had significant effect.The measure of effect size is large due to the large value of Cohen's d (0.5778 > 0.30 )

Step-by-step explanation:

From the question we are told that

The sample size is n=16

The sample mean is $M = 50.2$
